Low pH, aluminum (Al) toxicity, and low phosphorus (P) often coexist and are heterogeneously distributed in acid soils. To date, the underlying mechanisms of crop adaptation to these multiple factors on acid soils remain poorly understood. In this study, we found that P addition to acid soils could stimulate Al tolerance, especially for the P-efficient genotype HN89. Subsequent hydroponic studi...

The genome sequence of Streptomyces coelicolor A3(2) contains more than 50 genes coding for putative lipolytic enzymes. Many studies have shown the capacity of this actinomycete to store important reserves of intracellular triacylglycerols in nutrient depletion situations. In the present study, we used genome mining of S. coelicolor to identify genes coding for putative, non-secreted esterases/...

Plant salt tolerance is associated with a high rate of root growth. Although growth governed by cell wall and apoplastic pH, the relationship between these factors in elongation zone under salinity stress remains unclear. Herein, we assess pH- expansin-dependent extensibility, expansin expression salt-sensitive (Yongliang-15) -tolerant (JS-7) cultivars stress. A six-day 80 mM NaCl treatment sig...

An acid tolerance response (ATR) has been demonstrated in Listeria monocytogenes and Salmonella enterica serovar Typhimurium in response to low pH poised (i.e., adapted) with acetic or lactic acids at 20 degrees C and modeled by using dynamic differential equations. The ATR was not immediate or prolonged, and optimization occurred after exposure of L. monocytogenes for 3 h at pH 5.5 poised with...

Although water and land pollution are very dangerous, air pollution has its own peculiarities due to its transboundary dispersion of pollutants over the entire world. In any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. In the present study, Air pollution tolerance index was calculated for var...

There is an increasing interest in the cultivation of wild edible plants (WEP) consideration their quality attributes and salt tolerance, which makes these species good candidates for cascade cropping systems (CCS). In systems, saline effluents from a salt-sensitive donor crop are used to irrigate receiving with greater tolerance. The objective this study was evaluate two WEP species, Picris hi...

Patients with pulmonary hypertension (PH) associated left heart disease usually have a complex comorbidity status and postcapillary component of PH. The presence identification combined post-/precapillary PH in cohort patients is reflected the more pronounced structural functional right ventricular changes due to higher vascular resistance. post-/ precapillary reduced exercise tolerance phenoty...

Synechocystis sp. strain PCC 6803 grows photoautotrophically across a broad pH range, but wild-type cultures reach a higher density at elevated pH; however, photoheterotrophic growth is similar at high and neutral pH. A number of PSII mutants each lacking at least one lumenal extrinsic protein, and carrying a second PSII lumenal mutation, are able to grow photoautotrophically in BG-11 medium at...

The use of yeasts tolerant to acid (low pH) and salt stress is of industrial importance for several bioproduction processes. To identify new candidate genes having potential roles in low-pH tolerance, we screened an expression genomic DNA library of a multiple-stress-tolerant yeast, Issatchenkia orientalis (Pichia kudriavzevii), for clones that allowed Saccharomyces cerevisiae cells to grow und...
