伍教授，你的要求不太清楚。I corrected you english based on my own understanding. My research is so much different from yours. It may not make sense to you. Please do not feel insulted if I over do. Hope this helps. Good luck with your grant application. ,:}VbQ:3I

Lepidium latifolium belongs to Brassicaceae, and is a relative to both Arabidopsis and Thellungiella halophila. It is a plant with broad spectrum stress tolerancse. It has higher salt tolerant than llungiella salsuginea, and resistant to many other traumatic environments, such as chilliness and drought. In Northern America, it is classified as a flood-tolerant and invasive species, nevertheless, it is widely distributed in salty and dehydrated soils in China. The mechanism of salt resistance of llungiella salsuginea has been extensively studied. Current understandings believe it is related to the constitution of many stress-related genes. The molecular mechanism of salt and other stress resistance of T. halophila is generally considered relating to a set of constitutively expressed REDOX genes, such as SOD, POD,and P5CS etc. The roots of Lepidium latifolium can differentiate Na+ and K+ more efficiently than that of Arabidopsis. The stress profile of L. latifolium is very similar to T. halophila, however, the underlying molecular mechanism of L. latifolium is still unknown. Is there any common pathways/mechanisms shared by these high stress resistance plants? And if this common pathway/mechanism does exist, is it relevant to other plants without morphological and structural spcieation/differentiation? Answering these questions are of significant importance in understanding universal stress tolerance. Based on our current knowledge of salt resistance physiology and Arabidopsis and Thellungiella genome and transcriptsome, we propose to invest the comparative transcriptsome and genome of L. latifolium. Specifically, we will clone some stress tolerant genes. This may genetically improve salt and other stress tolerance of crops in Brassicaeae.
