After 10 years of large scale, international research, a group of scientists has finally assembled the wheat genome to its most complete and contiguous state. Assembling the genome took a total ...Wed, 15 Nov 2017 17:00:00 +0800EuropeDiscovery Brings Scientists One Step Closer to Crops with Twice the Yieldshttp://www.isaaa.org/kc/cropbiotechupdate/article/default.asp?ID=15966Scientists from Wageningen University and Research have found natural genetic variation for photosynthesis in plants and are unravelling it to the DNA level. Led by Mark Aarts and Jeremy Harbinson, the research team has shown that thale cress has various genes involved in adaptation to the changes in the amount of light to which plants are exposed....Wed, 15 Nov 2017 17:00:00 +0800EuropeSarcotoxin IA Gene from Flesh Fly Confers Enhanced Resistance to Citrus Canker in Sweet Orangehttp://www.isaaa.org/kc/cropbiotechupdate/article/default.asp?ID=15970Citrus canker caused by Xanthomonas citri subp. Citri (Xcc), is a serious disease in citrus-producing areas. While different levels of resistance to the disease have been reported, they are not sufficient to provide disease control. Overexpression of antibacterial genes is a potential way to increase plant resistance.
