1 Μαΐ 2022 · Plant aging can be caused by many factors, such as telomere depletion, genomic instability, loss of proteostasis, changes in intercellular interaction, desynchronosis, autophagy misregulation, epigenetic changes and others. Plants have developed a number of mechanisms to increase lifespan.
20 Ιουλ 2022 · When studied together by microfluidics coupled with time-lapse microscopy, isogenic BY4741 and W303 yeast cells show two different forms of aging: one with decreased ribosomal DNA silencing and...
23 Νοε 2012 · Here, the discussion considers recent research that suggests a cell biological mechanism that operates in animals, fungi and plants to link nutritional state, growth, deteriorative ageing and autophagy.
The remobilization of photoassimilates and nutrients (mainly carbohydrates but also amino acids and other compounds) through the phloem from source organs to sink organs is crucial for plant performance, leaf senescence, and productivity. These source sink. –.
15 Φεβ 2021 · In a recent study, a great diversity in aging patterns was observed by comparing mammals, nonmammalian vertebrates, invertebrates, vascular plants, and a green alga, showing increasing, constant, and decreasing mortality with aging, for both long- and short-lived species.
Plants have developed a number of mechanisms to increase lifespan. Among these mechanisms are gene duplication ("genetic backup"), the active work of telomerases, abundance of meristematic cells, capacity of maintaining the meristems permanently active and continuous activity of phytohormones.
