2018-12-8 · Concepts related to stress memory Environmental changes can occur episodically or in a cyclic way over days seasons and years. Hence like animals plants are repeatedly exposed to different types of stresses and a previous stress exposure can alter their biochemical physiological and transcriptional responses to a subsequent event.
MEMORY MECHANISMS Plant memory is often characterized by heightened molecular re-sponses upon exposure to a subsequent stress which can be composed of an enhanced response (for instance hyperinduction of transcrip-tion Fig. 2A blue line) a more efficient response or a more rapid response. Several molecular mechanisms underpinning plant memory

2021-3-31 · Plant Stress Memory and Role of GABA and Calcium. During drought plants make use of a signaling molecule that they received from animals and which enables them to limit their loss of water. These molecules enable them to remember how dry each day was and creates a plant stress memory. Prof. Rainer Hedrich a plant scientist at Julius
The incomplete or selective reprogramming throughout the plant genome during gametogenesis and fertilization can explain the stochastic nature of the transgenerational inheritance of stress memory in plants observed in some studies (Molinier et al. 2006 Pecinka et al. 2009).

2018-12-8 · A previous stress exposure may result in a faster or stronger response when plants are challenged again by a stress event. This capacity of plants to "remember" a past stress and to respond in a different way to multiple stress exposures is called memory response. Despite the mechanisms promoting the plant memory response to abiotic stresses are not completely elucidated a growing
