    Abstract Drought is a severe environmental constraint, causing a significant reduction in crop productivity across the world. Salicylic acid (SA) is an important plant growth regulator that helps plants cope with the adverse effects induced by various abiotic stresses. The current study investigated the potential effects of SA on drought tolerance efficacy in two barley (Hordeum vulgare) genotypes, namely BARI barley 5 and BARI barley 7. Ten-day-old barley seedlings were exposed to drought stress by maintaining 7.5% soil moisture content in the absence or presence of 0.5, 1.0 and 1.5 mM SA. Drought exposure led to severe damage to both genotypes,… More >

    Phyton-International Journal of Experimental Botany, Vol.91, No.6, pp. 1153-1164, 2022, DOI:10.32604/phyton.2022.019520

    Abstract Agrobacterium-mediated transformation has been widely used in plants. However, the mechanism in plant cells’ response to Agrobacterium infection was very complex. The mechanism of the determinants in host cell remains obscure, especially in barley, which is recalcitrant for Agrobacterium-mediated transformation. In the present study, microspore-derived embryogenic calli (MDEC) from barley elite cultivar were employed as unique subjects to characterize the mechanisms during the Agrobacterium infection process. Hua 30 MDEC can be successfully infected by Agrobacterium. RNA-sequencing at different infection points (0, 2, 6, 12, 24 hpi) was performed. The average expressional intensity of the whole genomics increased from 0 to… More >

    BIOCELL, Vol.45, No.6, pp. 1673-1685, 2021, DOI:10.32604/biocell.2021.016316

    Abstract RAV (Related to ABI3/VP1) transcription factors are unique members of the AP2-ERF superfamily with AP2 and B3 domains and play important roles in the regulation of seed germination, plant growth, and stress response. In the study, 7 RAV genes, named HvRAVs, were identified in barley based on the available genome sequences. While five of the seven HvRAVs were located on chromosome 3, HvRAV5 and HvRAV7 were located on chromosome 1 and 4, respectively. Six of the predicted HvRAVs were intron-less, except HvRAV2, which had one intron. HvRAV proteins have shown basic, instable, and hydrophilic properties. The AP2 domain specific RAYD… More >

    Phyton-International Journal of Experimental Botany, Vol.87, pp. 183-190, 2018, DOI:10.32604/phyton.2018.87.183

    Abstract Changes in root architecture are a strategy used by plants to explore the soil for available resources. The presence of beneficial microorganisms in the rhizosphere as well as plant growth regulators can cause changes in root development and promote the availability of water and nutrients. The effect of microorganisms or growth regulators on plant growth has been tested, but little is known about the effect they have on the architecture of the root of Hordeum vulgare L. Therefore the objective of this study was to evaluate the effect of the application of Rhizoglomus intraradices, Azospirillum brasilense, quercetin and epibrassinolide, alone… More >
