Subject:
biotechnology; climate change; drought; drought tolerance; genome; genomics; water holding capacity
Abstract:
... Climate change necessitates increased stress resilience of food crops. We describe four potential solutions, with emphasis on a relatively novel approach aiming at true tolerance of drought rather than improved water-holding capacity of crops, which is a common approach in current breeding and genome editing efforts. Some Angiosperms are known to tolerate loss of 95% of their cellular water, witho ...

Abstract:
... Resurrection plants have an extraordinary ability to survive extreme water loss but still revive full metabolic activity when rehydrated. These plants are useful models to understand the complex biology of vegetative desiccation tolerance. Despite extensive studies of resurrection plants, many details underlying the mechanisms of desiccation tolerance remain unexplored. To summarize the progress i ...

The desiccation tolerant “resurrection plant” Myrothamnus flabellifolia Welw. is distributed throughout southern Africa and is vicariantly separated between arid Namibia and the comparatively mesic South Africa where it is subjected to contrasting climate regimes. Our earlier study indicated ...

Abstract:
... Resurrection plants are a polyphyletic group of angiosperms which display true desiccation tolerance (DT) - the ability to survive near complete loss of cellular water for extended periods while recovering metabolic competence upon watering. This is achieved by employing tailored protection behaviours depending on the relative state of (de)hydration. Recent work has raised interest in desiccation- ...

Abstract:
... Desiccation tolerance has evolved recurrently across diverse land plant lineages as an adaptation for survival in regions where seasonal rainfall drives periodic drying of vegetative tissues. Growing interest in this phenomenon has fueled recent physiological, biochemical, and genomic insights into the mechanistic basis of desiccation tolerance. Although, desiccation tolerance is often viewed as b ...
