摘要

摘要:棉子糖家族寡糖(Raffinose family oligosaccharides, RFOs)是蔗糖的α-半乳糖衍生物，在植物中普遍存在，并在调节植物对各种非生物胁迫的反应中发挥关键作用。rfo在植物籽粒/果实或营养部位积累到很高水平，通常与可储存性、干燥性或耐寒性有关。最近的研究也揭示了rfo在种子萌发、植物发育和生物抗逆性中的调节作用。本文综述了植物中rfo的代谢、转运和进化及其在生理上的重要性。最近的研究强调了rfo在植物发育和胁迫反应中的普遍重要性。

Raffinose Family Oligosaccharides: Crucial Regulators of Plant Development and Stress Responses

Abstract Raffinose family oligosaccharides (RFOs), the α-galactosyl derivatives of sucrose, are nearly ubiquitous in Plantae, and they have been demonstrated to play pivotal roles in regulating plant responses to various abiotic stresses. RFOs accumulate to high levels in plant kernels/fruits or vegetative parts and are commonly associated with storability and desiccation or cold tolerance. Recent studies have also revealed the regulatory roles of RFOs in seed germination, plant development, and biotic stress resistance. Here, we provide an overview of the metabolism, transport, and evolution of RFOs as well as their physiological importance in plants. Recent research highlights the general importance of RFOs in plant development and stress response.

期刊介绍： Critical Reviews in Plant Sciences focuses on presenting in-depth and up-to-date reviews of timely and/or cutting-edge subjects in the broad discipline of plant science, ranging from molecular biology/biochemistry through the areas of cell biology, plant pathology and physiology, genetics, classical botany, and ecology, to practical agricultural applications. Articles in the journal provide an up-to-date literature base for researchers and students, pointing the way towards future research needs. The journal is also a significant source of credible, objective information to aid decision makers at all levels.
