The major mineral elements taken up from the soil by plant life are N, P, S, K, Ca and Mg, but Na and Cl, which have less specific functions, are included in the context of contributions by other speakers. In this paper no consideration is given, except in passing, to N because ...
important role in generating the variation needed to adaptation of various stressors and/or proliferation of TEs is triggered by stressful events. Although a clear causal and or mechanistical role of TEs in adaptation, like in many other systems is still lacking28,29, it is clear TEs have had...
3d). At higher magnification, Fe was found to be mainly located at the periphery of sieve elements (Fig. 3e). This periphery is probably the apoplast of phloem, because the LPR2 responsible for this Fe deposition is a cell wall-resident protein. Since the phloem vasculature was difficult ...
Secondary X-rays generated by the interaction of electrons with various elements in the specimen may be used for electron microprobe analysis. High voltage electron microscopy (HVEM) has two advantages, the increased voltage shortens the wavelength of the electrons (and therefore increases resolving ...
In brief, it may be stated that life, and in particular human life, is sensitive to even very small changes in certain critical elements. Among these, a well-established case is that of ultraviolet radiation penetration to the surface, which, as discussed in section 2.3.1, depends on the ...
The manifold cellular and physiological effects of large genomes may be a function of selection on the major components that contribute to genome size, such as transposable elements and gene duplication. To understand the nature of selection on these genomic components, both population-genetic and ...
New Chinese style, a new style that ingeniously combines traditional Chinese elements with modern simple style, shows the uniqueness, inclusiveness and fashion of Chinese traditional culture because of the coexistence of ancient charm and new ideas at the moment when western aesthetics are popular. Thi...
Fructose can be defined as the simple monosaccharide that can be found in many plants. It is directly absorbed by the body during digestion. It is sweeter than glucose. It is used as an added sugar in many food items.Answer and Explanation: ...
The dating technique that was used does have its intrinsic limitations, as the turnover of repetitive elements in plants is relatively rapid. For example, in Nicotiana spp., there is near-complete genome turnover of repetitive elements in as little as five million years39, and for O. sativa...
Drastic changes in vegetation structure caused by exceeding ecological thresholds have fueled the interest in tropical forest responses to climate and land-use changes. Here, we examine the potential successional trajectories experienced by the largest dry tropical forest region in South America, driven ...
