The involvement of ER calcium in abiotic stress tolerance
… plants exhibited better salt and osmotic tolerance, increased survival in soil under intermittent drought conditions, longer root growth, higher chlorophyll content, and higher total seed production compared to GFP transgenic plants and control plants. One member of the CIPK …

Effects of vermicomposted spent mushroom compost on growing medium characteristics, plant growth, yield and abiotic stress tolerance
… compost increased plant growth and reduced plant stress under conditions of cold stress, but not salinity or heat stress. The addition of 20% vermicompost to cold-stressed plants increased plant growth by an average of 30% and increased chlorophyll fluorescence by an average of 21%. Compared to …

XvGoIS, a galactinol synthase is transcriptionally upregulated under water deficit : the role of raffinosaccharides in abiotic stress tolerance in the resurrection plant Xerophyta viscosa (Baker)
… to genetically manipulate maize for increased abiotic stress tolerance, we have isolated and identified a number of genes from the resurrection plant Xerophyta viscosa (Baker) that are differentially expressed during water deficit. A cDNA was isolated from a library constructed from the leaves …

Characterisation of galactinol synthase II (XvGolSII) from the resurrection plant Xerophyta viscosa (Baker)
… and cope for extended periods with extreme abiotic stresses such as dehydration and cold stress. It is therefore of great interest to understand and elucidate the various molecular mechanisms which are specifically regulated in response to abiotic stress by identifying genes and proteins …

Structure and Mechanism of Hormone Perception and Signal Transduction by Abscisic Acid Receptors
… acid (ABA) is a vital plant hormone that confers abiotic stress tolerance. ABA acts through inhibition of certain members of the type 2C protein phosphatase (PP2C), resulting in activation of the SNF1-related kinases (SnRKs) that positively transduce the ABA signal. The identity of ABA receptors …

The role of the BHLH038 transcription factor in the regulation of osmotic and drought stress responses in Arabidopsis thaliana
The most important abiotic stress affecting agriculture worldwide is drought. In order to ensure food supply for the expanding world population two critical tasks must be undertaken; maintenance of crop yield as well as the increase of yield potential. Plants have built up a complex stress response …

Assessing wild barley germplasm in multiparent and advanced backcross populations for mapping, gene discovery, and improvement of malting barley
… alleles for several disease resistance and abiotic stress tolerance traits, and due to its extensive diversity, it is a key target for expanding the limited diversity of cultivated breeding germplasm. Therefore, our aim was to create and characterize populations that incorporate diverse …

Influence of plant species, location, and seasonality on rhizosphere bacterial communities in freshwater wetlands
… functions, including development and growth and abiotic stress tolerance. Rhizosphere microbial communities have been shown to vary according to differences in wetland vegetation. Owing to the complexity of factors influencing soil microbial community structure, a greater knowledge of the …

Characterization of the Role of miR156-SPL12 Regulatory Module in Root Architecture and Stress Response in Medicago sativa (alfalfa)
… various aspects of plant development and stress response by silencing a group of SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE (SPL) transcription factors. The Hannoufa lab previously showed that transgenic alfalfa (Medicago sativa L.) plants overexpressing miR156 display increased nodulation, …

The functional analysis of XhLEA3-2 - a LEA_4 from the resurrection plant, Xerophyta humilis
… the molecular mechanisms of desiccation tolerance are only somewhat understood, and considerable investigation is still required. Xerophyta humilis is a monocotyledonous resurrection plant in which one of the responses to extreme water loss is the upregulation of several Late …

Analysis of the sltA (stzA) gene and its orthologues in Aspergillus nidulansand other filamentous fungi
… with the encoded transcription factor regulating tolerance to cations, DNA-damaging agents and high arginine concentrations. The similar severe sensitivity of a sltA1 mutant (GO281) and stzA deletion mutants to these stresses indicated that the premature termination codon in sltA1 represents a …

Herbicide resistance in kochia and wheat: the loss and gain of weed control tools for wheat production
… invaded many settings of the American West. Its abiotic stress tolerance, tumble seed dispersion mechanism, and ability to outcross allow it to invade new areas and maintain genetic diversity for selection to act on. In a study reported here, I identify the genetic basis of resistance to the …

Characterization of tomato root-endophytic fungi and analysis of their effects on plant development, on fruit yield and quality and on interaction with the pathogen Verticillium dahliae
… them promote plant growth and confer increased abiotic-stress tolerance and disease resistance. According to such possible effects on host plants, it was aimed to isolate and to characterize native fungal root endophytes from tomato (Lycopersicon esculentum Mill.) and to analyze their effects on …
