Longevity and ageing in plants and plant organs 来自 Springer 喜欢 0 阅读量: 20 作者: E Wangermann 摘要: Many nineteenth century biologists interested themselves in the problems of ageing and rejuvenation. These problems are difficult to study because it is not easy to separate the effects ...
CONSTITUTION: A method for delaying senescence of plants comprises transforming plants with a gene encoding a protein having the amino acid sequence set forth in SEQ ID NO: 2, wherein the gene is ORE8 gene having the nucleotide sequence set forth in SEQ ID NO: 1; the ORE8 gene is ...
Unmanipulated flowers remained open for ~10 days, while hand-pollinated flowers closed earlier (~7 days), indicating that these flowers are subject to pollination-induced senescence. In 2002, pollen removal was rapid (~70% of pollen was removed in the first 2 h of anthesis), while female ...
then stays low and relatively constant (i.e., prime-age stage) and finally starts to increase. The age when mortality starts to increase is the age at the onset of senescence or aging,
The signal molecules generated in plants by the LOXs-pathway are involved in a variety of functions, including growth and development, seed germination, response to biotic and abiotic stresses, wounding, fruit ripening, senescence, cell death, and the biosynthesis of the stress-response phytohormones...
senescence or aging, and the intensity of the increase in the mortality rate with age is defined by the rate of senescence or aging. Males and females can differ in longevity in various ways. For instance, males and females can differ in the annual adult mortality (b), the age at the ...
Senescence and Grain Yield under Field Conditions Longevity of leaves directly influences grain yield of wheat (Triticum aestivum L.), but is greatly diminished by environmental stresses. The objective of ... M Benbella,GM Paulsen - 《Agronomy Journal》 被引量: 157发表: 1994年 Scientific Basis ...
In any root segment death of the cortex cells preceeded that of the stele. At the late grain filling stage all laterals along the main root exhibited advanced senescence, but stainable nuclei were seen in the root tissues of the basal part of 1st order laterals (both cortex and stele) ...
Our understanding of the process of autophagy and its role in health and diseases has grown remarkably in the last two decades. Early work established auto
Survival data plotted for the three cultures approached the typical sigmoid or semirectangular curve characteristic of an animal population having a senescence. Longevity was variable, and depended upon sex, culture, and holding conditions. Greatest longevity was demonstrated by male weevils from Mexico ...
