Battle to Save the US Citrus Industry Hinges on Consumer Acceptance of GM Food |
 The battle to save the multi-billion dollar citrus industry in the U.S. from the incurable disease called Huanglongbing or HLB, has prompted scientists to explore the possibility of breeding genetically modified (GM) trees that are resistant to the disease. However, given the controversy over the safety of GM food, scientists need to know whether producers will adopt this technology and whether shoppers will buy and consume GM citrus fruit. A recent study has some encouraging answers.

Transgene-Free Genome Editing in Tomato and Potato Plants Using CRISPR-Cas9 Cytidine Base Editor |
 Plant scientists are now using genome editing tools to explore on gene function and develop crops for improvement of traits. One of the technical challenges in using such tools is to efficiently induce precise and predictable targeted point mutations for crop breeding. Thus, new additional tools have been developed such as cytidine base editors (CBEs), which are CRISPR-Cas9 derived tools used to direct cytidine to thymine base conversion. In dicots, the most stable genomic integration of CRISPR-Cas9 is through Agrobacterium-mediated transformation. However, elimination of the foreign DNA may be hard to accomplish, particularly in vegetatively propagated plants.
