Variability in Functional Traits along an Environmental Gradient in the South African Resurrection Plant Myrothamnus flabellifolia

open access: yesPlants, 2022
Many desiccation-tolerant plants are widely distributed and exposed to substantial environmental variation across their native range. These environmental differences generate site-specific selective pressures that could drive natural variation in ...

LOSS OF DESICCATION TOLERANCE IN SEEDS OF TREE SPECIES DURING GERMINATION: THEORETICAL AND PRACTICAL IMPLICATIONS

open access: yesRevista Árvore, 2018
Understanding the loss of desiccation tolerance is of great importance in seed technology for its implications in the development of strategies for seed conservation and seedling production.

An Experimental Evolution Test of the Relationship between Melanism and Desiccation Survival in Insects. [PDF]

open access: yesPLoS ONE, 2016
We used experimental evolution to test the 'melanism-desiccation' hypothesis, which proposes that dark cuticle in several Drosophila species is an adaptation for increased desiccation tolerance.

Molecular responses to dehydration and desiccation in desiccation-tolerant angiosperm plants [PDF]

open access: yesJournal of Experimental Botany, 2018
Due to the ability to tolerate extreme dehydration, desiccation-tolerant plants have been widely investigated to find potential approaches for improving water use efficiency or developing new crop varieties. The studies of desiccation-tolerant plants have identified sugar accumulation, specific protein synthesis, cell structure changes, and increased ...

Induction of desiccation tolerance in desiccation sensitive Citrus limon seeds [PDF]

open access: yesJournal of Integrative Plant Biology, 2019
AbstractMany economically important perennial species bear recalcitrant seeds, including tea, coffee, cocoa, mango, citrus, rubber, oil palm and coconut. Orthodox seeds can be dried almost completely without losing viability, but so‐called recalcitrant seeds have a very limited storage life and die upon drying below a higher critical moisture content ...

ROS Accumulation as a Hallmark of Dehydration Stress in Primed and Overprimed Medicago truncatula Seeds

open access: yesAgronomy, 2022
Seed priming protocols implement incomplete imbibition phases, as well as physical, chemical or biological treatments, to activate pre-germinative metabolism and stress response, thus improving germination performances, seedling establishment and stress ...

Physiological, cellular and molecular aspects of the desiccation tolerance in Anadenanthera colubrina seeds during germination

open access: yesBrazilian Journal of Biology, 2017
During germination, orthodox seeds become gradually intolerant to desiccation, and for this reason, they are a good model for recalcitrance studies. In the present work, physiological, biochemical, and ultrastructural aspects of the desiccation tolerance
