Lignin is a complex polymer deposited in the cell wall of specialised plant cells, where it provides essential cellular functions. Plants coordinate timing, location, abundance and composition of lignin deposition in response to endogenous and exogenous
platuraMeigen andAtherigona orientalisSchiner have been reported as major pests of crops in the Brassicaceae, Poaceae, Alliaceae, Fabaceae, and Cucurbitaceae families; however, the latter is sporadically reported as a minor pest of onions in countries, such as the United States. Nocturnal insect p...
One of the clearer demonstrations of the importance of biotic interactions in host choice involves mutualism with ants. Atsatt (1981) has shown that lycaenid butterflies select hosts according to the probability of ant attendance on the plant; nutritionally superior hosts that lack ants are not ...
In France, the Rhone and the Rhine are two major rivers most impacted by human activities. They have been strongly modified by the construction of dams, by wastewater treatment plant inputs and by hydro-electrical facilities. Both rivers have previously been studied mainly for the most common he...
The two-component system (TCS) consists of histidine kinase (HK), histidine phosphate transfer protein (HP), and response regulatory factor (RR). It is one of the most crucial components of signal transduction in plants, playing a significant role in regulating plant growth, development, and re...
In an ecosystem, what is the role of phytoplankton? What are the main ecological roles of bacteria in the ecosystem? What are some of the biotic and abiotic phenomena that exist in the tundra? (a) What are abiotic factors? Give examples of the major abiotic factors that influence w...
The 52 significant markers identified under AS conditions had a major effect on the traits they are controlling as they explained more than 10% of the phenotypic variations (Table3and TableS5). The highest number of significant markers was identified for LA and KL in seedling and mature growth...
The mosaic structure of the forest-steppes is resulted from abiotic conditions, as well as the presence of herbivores and natural fires. The components of forest-steppes contribute differently to the overall conservation value of the whole landscapes due to the mosaic character. Forest patches can ...
Plants usually produce defence metabolites in non-active forms to minimize the risk of harm to themselves and spatiotemporally activate these defence metabolites upon pathogen attack. This so-called two-component system plays a decisive role in the chemi
Components of Ecosystem:An ecosystem comprises living and non-living organisms that interact to form a balanced structure in the environment. These components maintain the ecosystem's equilibrium by maintaining biological cycles and other activities....
