... 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 ...
droughttolerance, 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 ...
droughttolerance, etc ; apples; cultivars; transcription (genetics); transcription factors; Show all 5 Subjects
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:
... 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 ...
droughttolerance, etc ; climate; drought; mountains; phenology; vegetation; China; Show all 7 Subjects
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. ...

Abstract:
... Droughts are a frequent natural phenomenon that has amplified globally in the 21st century and are projected to become more common and extreme in the future. Consequently, this affects the progress of drought indices and frameworks to categorize drought conditions. Several drought-related indices and variables are required to capture different features of complex drought conditions. Therefore, we ...

Abstract:
... In Central Russia, the area of possible effective use of raspberry varieties and their productivity and production values are determined by the plant tolerance to a complex of adverse environmental factors. In this regard, the introduction of new varieties and hybrids should be accompanied by analyzing not only their productivity, but also their winter hardiness and drought resistance. In this pap ...

Abstract:
... The genetic architectures of agronomic and yield-related traits are expected to involve multiple loci that are unlikely all to segregate for alternative alleles in a single biparental population. Therefore, the identification of quantitative trait loci (QTL) that are expressed in diverse genetic backgrounds of multiple bi-parental populations provides evidence about both background-specific and co ...

Abstract:
... 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 ...

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 ...
