BiP overexpression improves leaf water relations during droughts and delays drought-induced leaf senescence. However, whether BiP controls cellular homeostasis under drought conditions or simply delays dehydration-induced leaf senescence as the primary cause for water stress tolerance remains to be determined. To address this issue, we examined the drought-induced transcriptomes of BiP-overexpr...

To a word w, we associate the rational function Ψw =

Root anatomical responses to water deficit are diverse and regulation of water uptake strongly depends on plant anatomy. The ancestors of common bean (Phaseolus vulgaris L.) cultivars are the wild common beans. Because wild beans adapt and survive well in the natural environment, it is hypothesized that wild common bean roots are less affected than those of domesticated beans at low substrate w...

We consider the family of rational functions ψw = ∏ (xwi − xwi+1) indexed by words with no repetition. We study the combinatorics of the sums ΨP of the functions ψw when w describes the linear extensions of a given poset P . In particular, we point out the connexions between some transformations on posets and elementary operations on the fraction ΨP . We prove that the denominator of ΨP has a c...

in order to study the effects of conventional and conservation tillage with management residue on wheat physiological properties, a field experiment was conducted in 2013-2014 at mashhad agricultural and natural resources research center of razavi khorasan province. this experiment was carried out as split plot design based on a randomized complete block design with three replications. main plo...

This study aimed at evaluating the effects of culture media and environmental factors (temperature water potential (Ψw)) on growth pathogenic fungus Phytopythium vexans (de Bary) associated with root rot dieback disease in apple trees. Tomato agar, potato dextrose agar (PDA), soybean were most favourable for rapid mycelial growth, optimum recorded PDA medium. To determine conditions that promot...

Aluminum (Al)-induced decrease in leaf hydration has been associated with low gas exchange, especially stomatal conductance (gs). However, the mechanisms explaining these responses are unclear. Citrus limonia was exposed to 0 and 1480 μM Al nutrient solution for 90 days test whether gs plants is increased 9-cis-epoxycarotenoid dioxygenase (NCED) gene expression abscisic acid (ABA) biosynthesis....

Bushfire management which incorporates fire potential indices is still in its infancy Jamaica and the Caribbean. In this study three bushfire indices—Keetch–Byram Drought Index (KBDI), Vapour Pressure Deficit (VPD) Water Potential (Ψw)—are calculated for south-central where frequencies are highest. The skills of evaluated using their representation normalised climatology, monthly seasonal (Dece...

Cowpea (Vigna unguiculata (L.) Walp.) is a leguminous species widely cultivated in northern and northeastern Brazil. In the state of Pará, this crop still has low productivity due to several factors, such as soil fertility climatic adversity, especially water deficiency. Therefore, present study aimed at evaluating physiological parameters cowpea plants under different depths. The experiment wa...

Despite the importance of Artemisia annua L. as the only source of the anti-parasitic drug artemisinin, little is known on the effects of biotic and abiotic stress on artemisinin accumulation. Water deficit is the most limiting factor on plant growth, however it can trigger secondary metabolite accumulation, depending on the plant growth stage and intensity. A. annua cultivated in growth chambe...
