| 英文简介 | Soil salinity is the major environmental factor limiting plant growth and productivity. Plant genetic engineering is recognized as an important way in improving the capacity of plant salt tolerance, developing and utilizing salinization land. Studying the salt-resistant mechanism and screening related genes of halophytes is the premise to do such jobs. Reaumuria trigyna is an endangerd small shrub native to the Eastern Alxa-Western Ordos area. This dicotyledonous recretohalophyte has superior ability to tolerate the stress imposed by saline soil environment. Since the transcriptome sequencing of R. trigyna was done, it could be considered as a reference species of recrehalophytes with detailed genomic information. According to our previous studies, ion excretion of R. trigyna via the multicellular salt glands plays vital role in its response to salinity, but little is known about the mechanisms underlying the unique adaption strategy. Based on the tanscriptome sequencing data, this project will 1) precisely separate and collect the salt glands of R. trigyna by using laser capture microdissection technology; 2) identify the unigenes associated with ion transport and vesicular transport in salt glands through hybridization with the small-scale microarray; 3) select 2-3 genes closely related to salt secretion, and transform them into Arabidopsis genome to analyze their functions; 4)investigate the net ion fluxes of individual salt gland in the leaves of R. trigyna under different treatments, such as plant hormone and stress signal molecule. The research conducted above will laid a foundation for further improvement and clarification of the salt-secreted mechanisms in this species and other recretohalophytes and will provide theoretical and practical proof for exploration of the excellent stress-resistant genes of R. trigyna. |
