Plants will die quickly if nitrogen is not sufficient. Nitrogen is most important to the plants in the vegetative phase when they are growing fast. During flowering, nitrogen levels can be decreased, but not entirely eliminated. Plants often show a nitrogen deficiency during the middle to the en...
Although P is abundant in the soil, plants can only absorb its inorganic forms such as phosphate (Pi), which has poor mobility. In Arabidopsis, the root tip is the major site in sensing Pi deficiency. Several Arabidopsis mutants, including pdr2, lpi, and lpr, have been isolated and shown...
The association between plants and arbuscular mycorrhizal fungi (AMF) affects plant performance and ecosystem functioning. Recent studies have identified AMF-associated bacteria as cooperative partners that participate in AMF–plant symbiosis: specific endobacteria live inside AMF, and hyphospheric bacteria ...
Reduced risk for positive soil-feedback on seedling regeneration by invasive trees on a very nutrient-poor soil in Seychelles Invasive plants sometimes alter habitat conditions so as to promote further invasion, either by the same or by other non-native species. Such positive feed... C Kueffer...
Collectively, the uptake by plants of nutrient elements is directed by multiple transporters, many of which transport more than one nutrient type. For example, although the iron-regulated transporter (Irt) is induced primarily by Fe deficiency, it transports Fe, Mn, Cu, Zn and possibly other ...
plants. N-deficient plants showed the most sensitive response; levels of some phenolic acids increased in N-deficient plants. In particular, levels of p-coumaric acid and ferulic acid in tops increased noticeably under N deficiency. Addition of Si in the medium decreased sinapic acid level in ...
Shoot growth and P and K uptake of the plants were promoted by the presence of hairs at all growth stages. Differences between genotypes were greater on loam than on sand until tassel emergence, presumably as additional exploitation by hairs is more relevant in loam. Compensation for the absence...
Riboflavin, a yellow, water-soluble organic compound that occurs abundantly in whey (the watery part of milk) and in egg white. An essential nutrient for animals, it can be synthesized by green plants and by most bacteria and fungi. The greenish yellow f
Generally, the spectral responses of plants to environmental conditions that impede growth show increased reflectance in the visible (380–720 nm) or infrared (720–1500 nm) range [2]. For instance, Masoni et al. (1996) investigated the impact of Fe, S, Mg, and Mn deficiency on the ...
