Abstract

A majority of plants possess stages in their life cycle at which specific tissues, mainly components of reproductive organs (mature pollen, seed) and dormant buds, can survive severe water loss. What is remarkable about resurrection plants is the ability of vegetative tissues (root, shoot, stem, leaves) to tolerate dehydration of the tissues and then return as functional units on rehydration. This phenomenon made resurrection plants exciting targets for molecular analysis of the poikilohydric ability and drought tolerance. Large-scale isolation of drought stress associated genes with unknown biological roles requires thorough functional analysis. Despite of the genetic and physiological complexity of desiccation tolerance, there are already examples where outcomes of targeted studies in resurrection plants are going to be directly utilized to engineer crop plants genetically. Here we show that conventional genetic transformation techniques, via in vitro plant regeneration systems, still represent an unavoidable part of the high-throughput technology chain of molecular breeding.
