摘要

本研究主要分析了不同干旱胁迫下向日葵杂种子叶和根系的表型性状(跨大田和室内试验)和转录变化。通过比较耐、敏感基因型中脱氢基因(DHNs)在干旱条件下的表达水平，以及实验室和田间筛选中生理反应的相关性，建立了一套高效、易于管理的向日葵幼苗试验测试系统。因此，在诱导水分胁迫下差异表达的DHNs基因(Rab18-like, Xero1和COR47-like)可以作为植物干旱存活评估的一个步骤，从而改善植物耐缺水胁迫育种计划中的预筛选试验。

Accumulation of Dehydrin Transcripts Correlates with Tolerance to Drought Stress in Sunflower

Present study was focused on the analyses of phenotypic traits (across field and laboratory trials) and transcriptional changes in cotyledons and roots of sunflower hybrids, exposed to different levels of drought stress. By comparing the level of dehydrins genes (DHNs) expression in tolerant and sensitive genotypes as response to drought and of the correlations between physiologic responses in laboratory and field screening, an efficient and easily manageable experimental test system for sunflower seedlings was established. Thus, DHNs genes (Rab18-like, Xero1 and COR47-like) differentially expressed under induced hydric stress could be used as a proceeding for estimation of plant drought survival, hence, improving the pre-screening trials in the breeding programs aimed on plant tolerance to water-deficit stresses.

期刊介绍： The Journal ROMANIAN AGRICULTURAL RESEARCH is an “open access” one, which publishes original articles, short communications, presenting new scientific results – theoretical, experimental and technical – on plant breeding and genetics, physiology, biotechnology, mineral nutrition and plant protection, in field crops. Reviews on up-to date subjects and recent research, preferably from Eastern Europe, may also be published.
