Grapevine rootstocks play a pivotal role in plant responses to water deficiency (WD); therefore, the selection of new genotypes is promising strategy for future agricultural managements aimed cope with climate changes. Recent studies reinforced central root system modulating WD responses, as it not only controls uptake and transport leaves, but also participates stress perception signalling sho...

intra-specific variations in apex development of two salt-tolerant cultivars (cross rowshan 11 (cr) and kharchia-65) and one salt-sensitive cultivar (ghods) of spring wheat (triticum aestivum l.) grown in sand culture at selected levels of salinity (0, 100, 200, and 300 mol m-3 nacl and cacl2 in 5:1 molar ratio) were studied. to determine the apex lengths and the number of spikelet primordi...

Effective innate and adaptive immune responses are essential for the control of hepatitis C virus (HCV) infection. Indeed, elimination of HCV during acute infection correlates with an early induction of innate and a delayed induction of adaptive immune responses. However, in the majority of acutely HCV-infected individuals, these responses are insufficient to clear the virus and persistence dev...

Natural killer (NK) cells are a subset of lymphocytes which play a crucial role in early innate immune response against infection and tumor transformation. Furthermore, they secrete interferon-γ (IFN-γ) and tumor necrosis factor (TNF) prompting adaptive immu-nity. NK cells distinguish the unhealthy cells from the healthy ones through an array of cell-surface receptors. Human NK cells use inhibi...

In the gene-for-gene hypothesis, Flor [19] proposed the existence of avirulence alleles of virulence genes, and that the virulence genes actively conditioned cultivar-specific virulence on hosts. Yet cultivar-specific virulence genes have not been found, and many of the avirulence (aŠr) genes cloned to date (over 40) do not appear to condition pathogenicity in general, virulence or anything els...

Genetic regulatory networks with adaptive responses are widely studied in biology. Usually, models consisting only of a few nodes have been considered. They present one input receptor for activation and one output node where the adaptive response is computed. In this work, we design genetic regulatory networks with many receptors and many output nodes able to produce delayed adaptive responses....

Carbon (C) and nitrogen (N) are two essential elements that influence plant growth and development. The C and N metabolic pathways influence each other to affect gene expression, but little is known about which genes are regulated by interaction between C and N or the mechanisms by which the pathways interact. In the present investigation, proteome analysis of N-efficient and N-inefficient Indi...

The effect of water deficit on stem reserve mobilization and sink activity in wheat (Triticum aestivum L.) cultivars, viz., C306 (drought tolerant) and PBW343 (drought sensitive) was studied. Drought was maintained in pot raised plants by withholding irrigation at 95 days after sowing (DAS), i.e. just five days before the initiation of anthesis. Drought induced a significant reduction in mean b...
