Domestication and breeding processes for developing modern wheat plants from diverse wild relatives and landraces have had unintended effects of loss of genetic diversity. This reduction in genetic variation undermines the ability of modern wheat cultivars to tolerate environmental stresses such as drought. Wheat wild relatives possess untapped genetic potential for tolerating abiotic stress, especially drought. Yet, their morpho-physiological adaptation and drought stress resilience mechanisms remain underexplored.

野生小麦亲缘种与在灌溉和雨养田间条件下生长的驯化小麦的干旱响应比较


从不同的野生亲缘种和地方品种中培育现代小麦植物的驯化和育种过程产生了遗传多样性丧失的意想不到的影响。这种遗传变异的减少削弱了现代小麦品种耐受干旱等环境胁迫的能力。小麦野生近缘种具有耐受非生物胁迫（尤其是干旱）的未开发遗传潜力。然而，它们的形态生理适应和干旱胁迫恢复机制仍未得到充分探索。
