1. Introduction to Bacterial Anhydrobiosis: A General Perspective and the Mechanisms of Desiccation-Associated Damage

Author:

Subject:
drought tolerance,   etc   ; air; anhydrobiosis;     Show all 3 Subjects
Abstract:
... Anhydrobiosis is the ability of selected organisms to lose almost all water and enter a state of reversible ametabolism. Such an organism dries up to a state of equilibrium with dry air. Unless special protective mechanisms exist, desiccation leads to damage, mainly to proteins, nucleic acids, and membrane lipids. A short historical outline of research on extreme dehydration of living organisms an ...

drought tolerance,   etc   ; Chromolaena odorata; allelopathy; evolution;     Show all 4 Subjects
Abstract:
... Invasive plants usually occur in limited areas in their native range but may spread into diverse environments in non-native ranges. Therefore, besides increasing competitive ability, evolution may also increase the tolerance of invading plants to environmental stress. In our previous study, we found that evolution facilitates invasive Chromolaena odorata by increasing the allelopathic effect. In t ...

Abstract:
... Self-rooted apple stocks are widely used for the production of apples worldwide. However, self-rooted apple stocks are weak due to shallow roots and poor grounding, resulting in poor drought resistance. Therefore, it is essential to understand the molecular mechanisms to develop self-rooted apple stock cultivars with drought resistance. We reported that MdFLP, an R2R3-MYB transcription factor, dir ...

Abstract:
... Microphylls, simple leaves with a single vein and no leaf gap, are the typical lycophyte leaves. However, Selaginella schaffneri has complex veins. Structural features and phylogeny associated with this unusual venation have remained unknown. We studied the leaf, venation, spore structures, and phylogeny of S. schaffneri, with S. erythropus as a typical Selaginella for comparison. Leaf veins of bo ...

Abstract:
... To date, very little research on drought tolerance has been conducted at the seedling stage in winter wheat. In this study, two types of traits, namely tolerance and recovery traits, associated with drought tolerance were scored in biparental mapping population (BPP) and association mapping population (A-set). The results of this study revealed no or weak significant correlation between the two ty ...

Abstract:
... Frequent droughts induced by climate warming have caused increasing impacts on the vegetation of the Loess Plateau (LP). However, the effects of drought on vegetation are highly dependent on when the drought occurs and how long it lasts during the growing season. Unfortunately, most of the existing drought indices ignore the differences in the drought effects on different vegetation growth stages. ...

Tropical dry forests are environmentally complex ecosystems with highly heterogeneous water availability, such that distinctive plant communities are found in contrasting habitats in close proximity to each other. This leads to the question of how resource heterogeneity has led to functional heterogeneity among communities. One hypothesis is that the main trade‐offs and the size of the functional ...

Colleters are secretory structures that protect meristems and developing organs from dehydration and attack by herbivores or pathogens. Colleters are common in Gentianaceae; however, there is little research from an anatomical ...
