Pamela Ronald (UC Davis) Part 2: Engineering Disease and Flood Resistant Rice Strains

http://ibioseminars.org/lectures/global-health-a-energy/pamela-ronald/pamela-ronald-part-2.html In Part 2, Ronald describes work from her lab that led to the discovery of a plant sensor of conserved microbial signatures called XA21. Subsequent discoveries in other laboratories revealed that mammals carry very similar receptors called TOLL-like receptors.The XA21 receptor recognizes a sulfated peptide conserved across a broad class of bacteria. Ronald's group has shown that the biological function of this molecule is to facilitate bacterial cell-cell communication. Ronald also describes exciting work that resulted in the development of rice strains that will survive and bear crop even after extended periods of submergence; a huge help to rice farmers in flood prone regions of the world.
