Effects of Rate of Drying, Life History Phase, and Ecotype on the Ability of the Moss Bryum Argenteum to Survive Desiccation Events and the Influence on Conservation and Selection of Material for Restoration [PDF]

Frontiers in Ecology and Evolution, 2019
Desiccation stress is frequently experienced by the moss Bryum argenteum and can influence survival, propagation and niche selection. We attempted to disentangle the interacting factors of life history phase (five categories) and rate of desiccation ...

Regulatory dynamics distinguishing desiccation tolerance strategies within resurrection grasses [PDF]

Plant Direct, 2022
Desiccation tolerance has evolved recurrently in grasses using two unique strategies of either protecting or dismantling the photosynthetic apparatus to minimize photooxidative damage under life without water (anhydrobiosis).

Life on the dry side: a roadmap to understanding desiccation tolerance and accelerating translational applications [PDF]

Nature Communications
To thrive in extreme conditions, organisms have evolved a diverse arsenal of adaptations that confer resilience. These species, their traits, and the mechanisms underlying them comprise a valuable resource that can be mined for numerous conceptual ...

Metabolite Profiling in Green Microalgae with Varying Degrees of Desiccation Tolerance [PDF]

Microorganisms, 2022
Trebouxiophyceae are microalgae occupying even extreme environments such as polar regions or deserts, terrestrial or aquatic, and can occur free-living or as lichen photobionts.

Sex Differences in Desiccation Tolerance Varies by Colony in the Mesic Liverwort Plagiochila porelloides [PDF]

Plants, 2022
Water scarcity, a common stress factor, negatively impacts plant performance. Strategies to cope with it, such as desiccation tolerance, are becoming increasingly important to investigate.

The Orthodox Dry Seeds Are Alive: A Clear Example of Desiccation Tolerance [PDF]

Plants, 2021
To survive in the dry state, orthodox seeds acquire desiccation tolerance. As maturation progresses, the seeds gradually acquire longevity, which is the total timespan during which the dry seeds remain viable. The desiccation-tolerance mechanism(s) allow

Bacterial hydrophilins promote pathogen desiccation tolerance. [PDF]

Cell Host Microbe, 2022
Acinetobacter baumannii is a leading cause of hospital-acquired infections, where outbreaks are driven by its ability to persist on surfaces in a desiccated state. Here, we show that A. baumannii causes more virulent pneumonia following desiccation and profile the genetic requirements for desiccation. We find that desiccation tolerance is enhanced upon

Desiccation Tolerance of Epiphytic Macrolichens in an Evergreen Temperate Rain Forest (Alerce Costero National Park, Chile) [PDF]

Plants
The Valdivian region has a temperate rainy climate with differences in rainfall throughout the year. This heterogeneity results in periods of summer drought that expose the poikilohydric epiphytes to desiccation.

LEA motifs promote desiccation tolerance in vivo. [PDF]

BMC Biol, 2021
Abstract Background Cells and organisms typically cannot survive in the absence of water. However, some animals including nematodes, tardigrades, rotifers, and some arthropods are able to survive near-complete desiccation.

Profiling of phenolic compounds in desiccation‐tolerant and non‐desiccation‐tolerant Linderniaceae [PDF]

Phytochemical Analysis, 2020
AbstractIntroductionCraterostigma plantagineum and Lindernia brevidens are resurrection plants, so these plants can tolerate desiccation of their vegetative tissues. Different components and mechanisms contribute to desiccation tolerance and secondary plant metabolites, like phenolic compounds, may play a role during these processes.ObjectivesSecondary
