Soybean [Glycine max (L.) Merrill] production plays a key role in the world economy. However, billions of dollars are lost yearly due to abiotic and biotic. Drought is considered one of the worst scourges of agriculture and the most serious cause of yield loss. The molecular biological studies of soybean for drought stress are behind compared to the studies of Arabidopsis and rice. In this study, molecular markers were established for soybean drought stress response. To reduce damage from drought stress, plants express several genes for stress tolerance and accumulates high intracellular levels of osmoprotectant compounds. These compounds include prolin and proline-rich protein, dehydrin, galactinol and raffinose. Molecular markers for drought stress resistant genes, including genes that encode these compounds, were constructed and gene expression was analyzed by RT-PCR. Soybean RNA samples were isolated from leaflets which were submitted to 30 min and 90 min of cellular dehydration. Results from RT-PCR showed that genes such as dehydrins, galactinol synthase, heat shock proteins and abscisic stress ripening-like protein were up-regulated after drought stress. These molecular markers might be useful to grasp the damage situation for drought stress in the field. |
