University students and educators from four universities have called for an expedited legislation on biotech crops under research and development in Uganda. This was during an inter-university dialogue on agricultural biotechnology, which was held at the School of Food Technology, Nutrition and Bioengineering Makerere University, Kampala on November 1, 2018. Students attending the event voiced the need for the National Biotechnology and Biosafety Bill to be passed by the parliament to enable Ugandan farmers access to improved biotech crops. 

"It is imperative that we do not just stop at discussing. Ugandan farmers urgently need this technology. Our political leaders need to pass enabling legislations to facilitate this," said Daniella Kagina, president of the Makerere University Debate Union. Dubbed as "Biotech Happy Hour", the event got many other students fired up, with compelling submissions in favor of modern biotechnology. Furthermore, the students asked that the discussion on agricultural biotechnology be taken further to the grassroots and special effort must be made to involve stakeholders who are skeptical of the technology.

The event, organized by Uganda Biosciences Information Center (UBIC), also featured a screening of the Food Evolution movie. The movie paints a picture of progress and navigates the thorny landscape of a heated global debate on agricultural biotechnology.

Over 80 participants appreciated the need to embrace modern agricultural biotechnology to address some of the most pressing challenges such as pests, diseases, and climate change. Furthermore, they pledged to engage their colleagues on this topic in a bid to further raise awareness and concretize support for the adoption of advancements in agriculture particularly in developing countries like Uganda.

In a related but separate event, farmers in Omoro district northern Uganda also called on their leaders to rally support for the delayed legislation on biotechnology. This was during a one-day biotechnology awareness workshop at Omoro District Council Hall on November 2, 2018, which brought together religious leaders, farmers, and local government representatives. The chief guest, Hon. Catherine Lamwaka, who is also Omoro district woman member of parliament promised to support the biotech bill and also present the farmers' views when the bill returns to parliament for debate this week.

PennState University researchers used rice seedlings to show that the stress of hotter temperatures may trigger a response in a plant's ribonucleic acid (RNA), which is a part of a cells' genetic messaging system, to manage this change in its environment.

The researchers studied over 14,000 different RNAs to look for changes in the RNA. Thus, they searched for changes in RNA's intricately folded structures that could signal acute heat stress. Since RNA is single-stranded, unlike the double-stranded DNA, it is able to fold back on itself and form more complex folds than DNA. They exposed two-week old rice seedlings to above normal temperatures for just ten minutes and compared with the control plants.

Results showed that the folds in the RNA of plants suffering from heat stress were looser than those in the control plants. The unfolding of the mRNA, a particular type of RNA, which transfers DNA instructions to the ribosome in a cell during the protein-making process, was also found to be correlated with a loss in the abundance of mRNA, suggesting that mRNA unfolding promotes its degradation, a method that cells use to regulate which genes express and when.

According to one of the researchers, Philip Bevilacqua, the results give hints on next steps for future research into more heat and drought resistant crops.

"So, if loss of structure results in loss of abundance and if that loss of abundance is not optimal, then you could imagine that we could change the sequences of the ends of the RNA, making them more stable, and, therefore, stabilize the production of those proteins," he said.

Asia and the Pacific

Scientists at the RIKEN Center for Sustainable Resource Science in Japan have found that the protein NGA1 is critical for plants to have normal responses to dehydration. In plants, dehydration response is regulated by the hormone abscisic acid (ABA). Successful rehydration requires accumulation of ABA during the early stages of dehydration, among other things. While scientists know how ABA does its work, they did not know much about how ABA begins to accumulate in response to dehydration stress. RIKEN scientist Hikaru Sato and his team screened 1,670 transgenic plant lines and performed a series of experiments to address this issue.

The team found a plant line with an overexpression of NGA with a chimeric repressor domain which resulted in reduced levels of the enzyme NCED3 during dehydration stress. This was very promising because plants need NCED3 to make ABA. The team hypothesized that NGA was a transcription factor that could control the production of NCED3, and ultimately the biosynthesis of ABA. They also found out that there is a whole family of NGA proteins, and showed that all of them bind to the region of the NCED3 gene that triggers its transcription.

The researchers then created transgenic plants for each member of the NGA family and found that NGA proteins are naturally found in different parts of plants, with different expression patterns during dehydration stress. The timing of NGA expression also varied among different plant lines which meant that not all of them function the same way during drought stress. From the mutants they created, they found that after withholding water until the plants withered, NGA1 mutants remained dried up and could not be revived through rehydration. All the other mutants could be rehydrated.

The USDA Foreign Agricultural Service organized two outreach events in Jakarta and Bogor on October 24 and 25, 2018 with the objective of advancing the public understanding and acceptance of modern biotechnology applications in agriculture. The events included lectures, collaborative ideas sessions and film screening of a Dutch documentary titled Well Fed, which were attended by a diverse group of stakeholders representing academia, government, and industry. A panel discussion on biotechnology and its status in Indonesia was conducted after the film showing.

The challenges in modern agri-biotech were discussed while laying out a path for continued engagement with policymakers and the public. It was concluded that outreach on biotech research and market access is vital since Indonesia has yet to allow the commercialization of GE crops. As part of the seminar, nine influential advocates were also identified, representing the scientific, farming, and research communities to serve as "Biotech Ambassadors". Dr. Mahalecthumy Arujanan of Malaysia Biotechnology Information Center and ISAAA's Dr. Rhodora Aldemita served as resource speakers in the two-day event.

The Philippines remain as Asia's biotechnology leader, according to the USDA Foreign Agricultural Service-Global Agricultural Information Network Report on agricultural biotechnology. The Philippines is the first Asian country to allow the planting of GM crop and is moving towards developing a regulatory framework for GE animals. In 2016, the original GE plant regulations (Department of Agriculture Administrative Order No. 8) was changed to the Joint Department Circular (JDC), which led to the slow processing of biosafety applications. According to the GAIN report, such delay in approvals may affect U.S. trade as well as the country's biotech leadership status in the region.

House Deputy Speaker Sharon Garin called for the passing of House Bill 7926 or the Modern Biotechnology Act of 2018, which promoted the safe and responsible use of modern biotech and for the establishment of the Biotechnology Authority of the Philippines that will serve as the policy-making body on biotech in the country.

Scientists from The University of Edinburgh have discovered a gene that could help develop disease-resistant crops. The scientists studied how plants produce nitric oxide when they are under attack from bacteria or viruses. Nitric oxide accumulates in plant cells and triggers a response from the plant's immune system.

The research team used Arabidopsis to study the genes that were triggered as nitric oxide levels rose. They found that a previously unknown gene – called SRG1 – is rapidly activated by nitric oxide and is also triggered during bacterial infection. Further studies showed that SRG1 activates the plant's defense mechanism by limiting the activity of genes that suppress the immune response. They also found that nitric oxide regulates immune response, which ensures that the plant's defense system does not over-react.

Plant communities and animals have typically performed better than monocultures. The mechanisms for this, however, have been a mystery for a long time. Biologists at the University of Zurich (UZH) have now identified the genetic cause of these mechanisms.

Two UZH researchers, Samuel Wüst and Pascal Niklaus, addressed this question by combining modern genetic and ecological approaches. They used systematic crosses of varieties of Arabidopsis plants, which were grown in pots in different combinations. A few weeks later, the researchers weighed the resulting biomass, which allowed them to compare the growth of the plants. As expected, pots with mixtures of different crosses were indeed more productive on average.

The researchers related the yield gain in mixed communities to the genetic makeup of the crosses. The genetic map they obtained helped them in identifying parts of the genome that made the combination of plants good mixed teams. They found that even the smallest genetic differences between plants were enough to increase their combined yield.

Pineapple is the second most important fruit crop next to banana. Besides its economic benefits, it is also a model species for Crassulacean acid metabolism pathway of photosynthesis in plants. An available genetic transformation method is required to further improve and study this plant. However, Agrobacterium-mediated transformation in pineapple suffer from low success rate, requiring researchers to find other ways to genetically modify this crop.

Researcher Yuan Chin from Fujian Agriculture and Forestry University in China and colleagues developed a simple protoplast isolation method that can be used for genetic transformation of pineapple. The protoplasts were isolated from cultured pineapple leaves. They tested the isolated protoplast for transient expression of proteins AtJAZ3 and AtMYC2 through PEG-mediated transformation. Results showed suitability of the method for studying protein localization and interaction. The researchers concluded that this method can also be used with genomic sequencing data to study molecular control of pineapple plant growth.

Unusual oils like hydroxy fatty acids (HFAs) are valuable in the chemical industry. They are largely produced in seeds of castor bean and lesquerella. However, the mass production of these plants is hindered by challenges such as difficulty in weed control and hazardous compounds also produced in these plants. Thus, researchers Niranjan Aryal and Chaofu Lu of Montana State University in the US engineered a gene from castor bean to oilseed Camelina to produce large amounts of HFAs.

The researchers expressed the gene RcPLCL1 from castor bean in Camelina via Agrobacterium-mediated transformation. To determine the oil content of the transgenic plants, the researchers extracted oil from the Camelina seeds using a modified Blight and Dyer method. Results showed increased HFA production and improved germination rate of Camelina seeds.

New Breeding Technologies

Important fruit crops apple and grapevine are subjects for crop improvement by conferring biotic and abiotic stress tolerance through traditional breeding and modern biotechnology. As approvals for field testing and commercialization have been limited in most crops, researcher Yuriko Osakabe from Tokushima University in Japan and colleagues explore genome editing to genetically improve apple and grapevine.

In their article in Nature, the group of researchers described two protocols, namely, plasmid-mediated genome editing and direct delivery of CRISPR-Cas9 ribonucleoproteins for genome editing of apple and grapevine. They transformed CRISPR-Cas9 components into protoplasts and verified mutations produced by the system. Results showed high efficiency and accuracy of the system in the two fruit crops, taking 2-3 weeks for genetic transformation of the CRISPR-Cas9 system and more than three months for plant regeneration and verification of the genome edits.

CRISPR-Cas9-mediated gene editing is enabled by the same methods as the production of genetically modified organisms. The only difference is that the transferred DNA sequence is sorted out of the plant at the end of the experiment, making the plant transgene-free. However, researcher Roman Jerala of National Institute of Chemistry in Slovenia and colleagues say that the insertion of the transgene at the earlier part of the experiment can cause unwanted mutations. Also, further expression of the transgene in the plant can cause off-target mutations. Therefore, the team proposed a method to skip transgene production in gene editing.

The team transformed Cas9 enzymes and guide RNA sequence with ribonucleoprotein into plant protoplasts using PEG-mediated transformation. Results showed up to 25 percent mutation frequency in genes FRI and PDS in the said species. They also observed positive correlation between amount of CRISPR components and mutation rate. The team aims to target other genes and study edited protoplast regeneration in the future.

Beyond Crop Biotech

Cases of Alzheimer's disease (AD), the most common form of dementia, is mostly sporadic, making it difficult for scientists to determine how the disease starts and develops. Notably, researcher Carlos Pascual-Caro from University of Extremadura in Spain and colleagues pave a step forward into finding a cure for the disease by discovering a gene linked to Alzheimer's.

In their article published in Journal of Molecular Medicine, they described the discovery of the STIM1 gene and how CRISPR helped in verifying its function and mechanism. By analyzing brain tissues from deceased AD patients and normal patients, researchers found deficiency in STIM1 in AD patients. Through CRISPR, the researchers discovered that deletion of the gene results to reduced transport of calcium ions through the plasma membrane, which causes the cell to die.
