The Solanaceae family includes some important vegetable crops, and they often suffer from salinity stress. Some miRNAs have been identified to regulate gene expression in plant response to salt stress; however, little is known about the involvement of miRNAs in Solanaceae species. To identify salt-responsive miRNAs, high-throughput sequencing was used to sequence libraries constructed from root...

Salt stress is a serious problem facing plant growth and development. Selenium (Se) could improve plant growth and reduced stress. Hence, the aim of this study was to determine whether the Se application could alleviate salinity stress negative effects on Melissa officinalis L. Different salinity levels in this research were control (0), 50, 100 and 200 mM. Simultaneously, sodium selenate (Se) ...

most plants encounter stress such as drought and salinity that adversely affect growth, development and crop productivity. the expression of the gene glutathione-s-transferases (gst) extends throughout various protective mechanisms in plants and allows them to adapt to unfavorable environmental conditions. gstf1 (the first phi gstfs class) gene expression patterns in the wheat cultivars mahuti ...

MicroRNAs (miRNAs), a class of small non-coding RNAs, recognize their mRNA targets based on perfect sequence complementarity. MiRNAs lead to broader changes in gene expression after plants are exposed to stress. High-throughput sequencing is an effective method to identify and profile small RNA populations in non-model plants under salt stresses, significantly improving our knowledge regarding ...

Piriformospora indica association has been reported to increase biotic as well as abiotic stress tolerance of its host plants. We analyzed the beneficial effect of P. indica association on rice seedlings during high salt stress conditions (200 and 300 mM NaCl). The growth parameters of rice seedlings such as root and shoot lengths or fresh and dry weights were found to be enhanced in P. indica-...

MicroRNAs (miRNAs) are a class of endogenous small RNAs with important roles in plant growth, development, and environmental stress responses. Ulmus pumila L., a deciduous broadleaved tree species of northern temperate regions, is widely distributed in central and northern Asia and has important economic and ecological value. With the spread and aggravation of soil salinization, salt stress has...

salt stress is a factor limiting crop growth and productivity around the world. developing salt tolerant cultivars using desired plant features has been considered as a way to cope with the problem. in this study, a factorial experiment was used in order to determine the effects of salt stress on stomatal length at abaxial and adaxial leaf surfaces, relative water content (rwc) and transpiratio...

To understand the cross-talk and specificity of the early responses of plants to salt and drought, we performed physiological and proteome analyses of Brassica napus seedlings pretreated with 245 mM NaCl or 25% polyethylene glycol (PEG) 6000 under identical osmotic pressure (-1.0 MPa). Significant decreases in water content and photosynthetic rate and excessive accumulation of compatible osmoly...

the effect of salinity was assessed on the activity of some major antioxidant enzymes i.e., superoxide dismutase (sod), peroxidase (pod), catalase (cat), in the seedlings’ roots or shoots of three winter canola (brassica napus l.) cultivars, colvert (tolerant), symbol (semi tolerant) and agat (susceptible). seedlings were treated with 0 (control), 50, 100 and 150 mm nacl for 24 h in hydropoic c...

Crop productivity continues to decline due to a wide array of biotic and abiotic stresses. Salinity is one of the worst abiotic stresses, as it causes huge losses to crop yield each year. Kinetin (Kn) has been reported as plant growth regulator since long, but its role in improving plant growth and food quality under saline conditions through mediating phytohormonal cross-talk is poorly studied...
