Plant stress memory
WebJul 26, 2024 · The shoot apical meristem is crucial for the growth of the organs above ground. Researchers led by Bernd Mueller-Roeber at the Max Planck Institute of Molecular Plant Physiology and the University of Potsdam have investigated how the shoot apical meristem responds to heat stress and found that it develops a stress memory. WebThe definition of plant stress memory implies that some sort of information persists in the plant after the stimulus removal and recovery period, influencing its subsequent response.

WebFeb 23, 2024 · When a naïve plant is exposed to a first drought stress (S1), the plant acquires a stress memory in the form of the histone mark H3K4me3 keeping the chromatin in a permissive state. However, S1 is followed by a period of recovery (R) during which the plant decides either to retain the memory and remain in a primed sate or to reset [ 12 ].
WebMar 7, 2024 · The findings, published in Nature Plants, explain a mechanism of how plants 'remember' the stress from a previous attack, and that this long-term memory is encoded in a family of 'junk DNA'... WebSuch stresses that plants remember and prime themselves for are drought, excessive light, oxidative stress, abscisic acid, and cold and warm climates. [8] Memories are formed in …
WebMar 19, 2024 · Plants are continuously exposed to stress conditions, such that they have developed sophisticated and elegant survival strategies, which are reflected in their phenotypic plasticity, priming capacity, and memory acquisition. WebMar 5, 2024 · Stressful environmental conditions, including heat stress (HS), are a major limiting factor in crop yield. Understanding the molecular mechanisms of plant stress memory and resilience is important for engineering more resistant plants and improving crop yield. To study how the different gene regulatory layers change upon repeated HS …
WebApr 11, 2024 · This unusual memory of the environment is unique to plants and distinct from how animals pass a genetic trait like eye color or height from one generation to the next. Lacking the ability to run away or seek shelter, plants must adapt to the elements to survive. Stressors such as drought or extreme temperatures induce a stress response that ...
