Abscission is a process that allows plants to shed unwanted organs. Plants can use abscission as a defense mechanism to shed leaves that are heavily infected with pathogenic bacteria. By shedding infected leaves, plants completely eliminate the bacteria from the plant body, thus preventing further ...
One reason for lack of a negative effect was that leaves were not dropped until miners had pupated in the leaf. The other reason is reduced parasitism; since parasitoids did not search fallen leaves, abscission actually decreased mortality due to these natural enemies. Overall, our results ...
Abscission is a process that allows plants to shed tissues or organs via cell separation, and occurs throughout the life cycle. Removal of leaves through the use of chemical defoliants is very important for mechanical harvesting of cotton (Gossypium hirsutum). However, our knowledge of the molecu...
China has experienced an unprecedented increase in nitrogen deposition over recent decades, threatening ecosystem structure, functioning, and resilience. However, the impact of elevated nitrogen deposition on the date of foliar senescence remains widely

Herbivore induced plant defence, however, does not appear to occur in Eucalyptus [33] but see [34]. Increased consumption of leaves, or compensatory feeding, is often observed in herbivorous insects as a response to plants grown under e[CO2]—this is to com- pensate for the dilution of ...
abscission zone of the petiole and stem. ) To form a concentration gradient to regulate the process of leaf abscission. Leaf fall generally occurs in the next stage of leaf senescence. In Arabidopsis, auxin can regulate leaf senescence by regulating the expression of IAA29 and WRKY57. In ...
Nutrient resorption from senescing leaves is a strategy for internal nutrient recycling during plant growth1that reduces dependence on the soil nutrient supply2. Previous studies show that leaf nutrient resorption efficiency, which is the proportion of nutrients withdrawn before leaf abscission, is closely...
