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 کاملEST-derived SSR markers from defined regions of the wheat genome to identify Lophopyrum elongatum specific loci.
Lophopyrum elongatum, a close relative of wheat, provides a source of novel genes for wheat improvement. Molecular markers were developed to monitor the introgression of L. elongatum chromosome segments into hexaploid wheat. Existing simple sequence repeats (SSRs) derived from genomic libraries were initially screened for detecting L. elongatum loci in wheat, but only 6 of the 163 markers teste...
متن کاملAnalysis of the Thinopyrum elongatum Transcriptome under Water Deficit Stress
The transcriptome of Thinopyrum elongatum under water deficit stress was analyzed using RNA-Seq technology. The results showed that genes involved in processes of amplification of stress signaling, reductions in oxidative damage, creation of protectants, and roots development were expressed differently, which played an important role in the response to water deficit. The Th. elongatum transcrip...
