Tomato seeds subjected to osmo-priming show fast and more uniform germination. However, osmo-priming reduces seed longevity, which is a complex seed physiological attribute influenced by several mechanisms, including response to stress. Thus, to have new insights as to why osmo-primed tomato seeds show a short life span, we performed a transcript analysis during their priming. For that, we performed gene expression studies of the heat-shock protein family genes that were previously reported to be associated with the enhancement of longevity in primed tomato seeds. Physiological assays of germination, vigour and longevity tests were used to support the data. The results show that the short life span of osmo-primed tomato seeds is related to the decrease in the expression of transcripts associated with response to stress during the priming treatment. These results are important because they add information regarding which seed longevity mechanisms are impacted by the priming treatment. In parallel, it will allow the use of these genes as markers to monitor longevity in osmo-primed tomato seeds.

番茄种子中的 Osmo 引发下调与应激反应相关的基因并导致寿命缩短
经渗透引发的番茄种子显示出快速和更均匀的发芽。然而,osmo-priming 会降低种子寿命,这是一种复杂的种子生理特性,受多种机制影响,包括对压力的反应。因此,为了对为什么 osmo 引发的番茄种子显示出短寿命有新的见解,我们在它们的引发过程中进行了转录分析。为此,我们对热休克蛋白家族基因进行了基因表达研究,这些基因先前被报道与增强番茄种子的寿命有关。发芽、活力和寿命测试的生理测定被用来支持数据。结果表明,osmo 引发的番茄种子寿命短与引发处理期间与应激反应相关的转录物表达减少有关。这些结果很重要,因为它们添加了有关哪些种子寿命机制受引发处理影响的信息。同时,它将允许使用这些基因作为标记来监测 osmo-primed 番茄种子的寿命。
