Early transcriptional response in Solanum sp. during drought stress conditions. Solanum

Cultivated tomato Solanum lycopersicum (Slyc) is sensitive to water shortage, while the wild relative Solanum peruvianum L. (Sper), an herbaceous perennial small shrub, can grow under water scarcity and soil salinity environments. The plastic S. peruvianum can modify the plant architecture when suffering drought, rechanging leaf organs; however, the early events that trigger the acclimation and improve these morphological changes are unknown. In this work, a transcriptomic approach has been used to understand the physiological processes that differentiate the response to drought stress during the early phase in both species.

栽培番茄（Solanum lycopersicum，简称Slyc）对水分亏缺敏感，而其野生近缘种秘鲁番茄（Solanum peruvianum L.，简称Sper）为多年生草本小灌木，可在缺水及土壤盐渍化环境中生长。具有表型可塑性的秘鲁番茄在遭遇干旱胁迫时可调整植株构型，改变叶片器官；但目前尚不明确触发其胁迫驯化进程、促成此类形态变化的早期事件。本研究采用转录组学（transcriptomic）方法，旨在解析两个物种在干旱胁迫早期阶段的差异化响应生理过程。
