Coordinate Gene Response to Salt Stress in Lophopyrum elongatum.
Lophopyrum elongatum is a highly salt-tolerant relative of wheat. A previous study showed that the abundance of a number of mRNA species is enhanced or reduced in the roots of the L. elongatum x Triticum aestivum amphiploid by salt stress. Eleven genes with enhanced expression in the roots of salt-stressed L. elongatum plants have been cloned as cDNAs. The clones were used as probes to characte...
متن کاملThe salt stress-inducible protein kinase gene, Esi47, from the salt-tolerant wheatgrass Lophopyrum elongatum is involved in plant hormone signaling.
Protein kinases play a central role in signal transduction in all organisms and to study signal transduction in response to salt stress we have identified and characterized a gene encoding a protein kinase that is induced by salt stress and abscisic acid (ABA) in the salt-tolerant wild wheatgrass Lophopyrum elongatum (Host) A. Love. The product of the early salt stress-induced gene, Esi47, was ...
متن کاملOn the evolution of the adaptation of Lophopyrum elongatum to growth in saline environments.
Most species of the genus Lophopyrum Löve (Agropyron Geartn.) grow in saline environments and are more tolerant of saline stress than the species of the related genus Triticum L. A 56-chromosome amphiploid from the cross Triticum aestivum cv. Chinese Spring x Lophopyrum elongatum exceeded Chinese Spring in salt tolerance, measured as plant dry-matter production and seed yield in solution cultur...
متن کاملResponse of Two Indica Rice Varieties to Salt Stress
Salinity is one of the most challenging problems that adversely affects growth and development of plants. Therefore, understanding of the mechanisms that enable plants to adapt to salinity stress will ultimately help in the selection of stress tolerant cultivars for exploiting saline soils. The main objective of this study was to examine the effects of NaCl on some physiological and biochemic...
متن کاملTHE RESPONSE OF FOLIAR PROTEINS IN TWO WHEAT (TRITICUM AESTIVUM) CULTIVARS TO SALT STRESS
Effect of various NaCl treatments (0, 50, 100, 200, and 300 mM) at different growth and development stages (tillering, boot swellen, flowering and anthesis) in two wheat cultivars (Ghods: salt – sensitive, Boolani: salt – resistant) on SDS-PAGE electrophoretic pattern of leaf proteins was studied under greenhouse conditions. Generally, in response to salinity treatments, the decrease in protein...
