Oryza officinalis 是水稻遗传改良的一种可利用的外来供体。对代表性稻种组的比较表明，野生稻和栽培稻亚种。粳稻具有相似的耐寒潜力。通过比较每个物种的转录网络，解决了不同或相似的遗传机制参与每个物种的低温反应的可能性。共同的转录组特征表明了相同的代谢、激素和防御状态，从而支持了总体相似性。然而，O. officinalis 维持了一个复杂的冷响应油菜素类固醇调节的 BES1 网络，该网络在 O. sativa 中似乎已破碎。 BES1-网络对于通过保护光合机制和维持气孔孔径、氧化防御和渗透调节来整合生长相关反应与生理调节和防御具有潜在的重要作用。等效的生理过程在水稻中发挥作用，但其遗传机制受到 ABA 依赖性、DREB 依赖性和/或与 BES1 解偶联的氧化介导网络的直接控制。虽然O. officinalis 和O. sativa 代表了长期的物种形成和驯化，但它们的耐寒潜力相当，涉及相同的生理过程，但具有不同的遗传网络。 BES1-网络代表了 O. officinalis 的一个新属性，在多样化或补充栽培种质中的其他机制方面具有潜在的应用。
Oryza officinalis is an accessible alien donor for genetic improvement of rice. Comparison across a representative panel of Oryza species showed that the wild O. officinalis and cultivated O. sativa ssp. japonica have similar cold tolerance potentials. The possibility that either distinct or similar genetic mechanisms are involved in the low temperature responses of each species was addressed by comparing their transcriptional networks. General similarities were supported by shared transcriptomic signatures indicative of equivalent metabolic, hormonal, and defense status. However, O. officinalis has maintained an elaborate cold-responsive brassinosteroid-regulated BES1-network that appeared to have been fragmented in O. sativa. BES1-network is potentially important for integrating growth-related responses with physiological adjustments and defenses through the protection of photosynthetic machinery and maintenance of stomatal aperture, oxidative defenses, and osmotic adjustment. Equivalent physiological processes are functional in O. sativa but their genetic mechanisms are under the direct control of ABA-dependent, DREB-dependent and/or oxidative-mediated networks uncoupled to BES1. While O. officinalis and O. sativa represent long periods of speciation and domestication, their comparable cold tolerance potentials involve equivalent physiological processes but distinct genetic networks. BES1-network represents a novel attribute of O. officinalis with potential applications in diversifying or complementing other mechanisms in the cultivated germplasm.
