LEAfing through literature: late embryogenesis abundant proteins coming of age-achievements and perspectives.

To deal with increasingly severe periods of dehydration related to global climate change, it becomes increasingly important to understand the complex strategies many organisms have developed to cope with dehydration and desiccation. While it is undisputed that late embryogenesis abundant (LEA) proteins play a key role in the tolerance of plants and many anhydrobiotic organisms to water limitation, the molecular mechanisms are not well understood. In this review, we summarize current knowledge of the physiological roles of LEA proteins and discuss their potential molecular functions.

The canonical RdDM pathway mediates the control of seed germination timing under salinity.

Plants respond to adverse environmental cues by adjusting a wide variety of processes through highly regulated mechanisms to maintain plant homeostasis for survival. As a result of the sessile nature of plants, their response, adjustment and adaptation to the changing environment is intimately coordinated with their developmental programs through the crosstalk of regulatory networks. Germination is a critical process in the plant life cycle, and thus plants have evolved various strategies to control the timing of germination according to their local environment.
