Adaptation Responses of Dioecious and Hermaphroditic Tree Species to Abiotic Stress

Molecular and physiological responses to abiotic stress in forest trees and their relevance to tree improvement.

Abiotic stresses, such as drought, salinity and cold, are the major environmental stresses that adversely affect tree growth and, thus, forest productivity, and play a major role in determining the geographic distribution of tree species. Tree responses and tolerance to abiotic stress are complex biological processes that are best analyzed at a systems level using genetic, genomic, metabolomic ...

Root Development and Abiotic Stress Adaptation

As soon as plants became independent from homogeneous aquatic environments, root-like organs were developed. The interface between land and water bodies was probably the medium for the earliest land plants. Taking into account that those ancestral root-like organs did not face problems of water and nutrient acquisition, they were probably rather simple. As the earliest plants colonized this med...

Abiotic Stress Signaling and Responses in Plants

As sessile organisms, plants must cope with abiotic stress such as soil salinity, drought, and extreme temperatures. Core stress-signaling pathways involve protein kinases related to the yeast SNF1 and mammalian AMPK, suggesting that stress signaling in plants evolved from energy sensing. Stress signaling regulates proteins critical for ion and water transport and for metabolic and gene-express...

Abiotic Stress in Plants and Metabolic Responses

Plant Responses to Simultaneous Biotic and Abiotic Stress: Molecular Mechanisms.

Plants are constantly confronted to both abiotic and biotic stresses that seriously reduce their productivity. Plant responses to these stresses are complex and involve numerous physiological, molecular, and cellular adaptations. Recent evidence shows that a combination of abiotic and biotic stress can have a positive effect on plant performance by reducing the susceptibility to biotic stress. ...
