Abstract:
Millets stand out as a sustainable crop with the potential to address the issues of food insecurity and malnutrition. These small-seeded, drought-resistant cereals have adapted to survive a broad spectrum of abiotic stresses. Researchers are keen on unravelling the regulatory mechanisms that empower millets to withstand environmental adversities. The aim is to leverage these identified genetic determinants from millets for enhancing the stress tolerance of major cereal crops through genetic engineering or breeding. This review sheds light on transcription factors (TFs) that govern diverse abiotic stress responses and play role in conferring tolerance to various abiotic stresses in millets. Specifically, the molecular functions and expression patterns of investigated TFs from various families, including bHLH, bZIP, DREB, HSF, MYB, NAC, NF-Y and WRKY, are comprehensively discussed. It also explores the potential of TFs in developing stress-tolerant crops, presenting a comprehensive discussion on diverse strategies for their integration.
摘要:
小米作为可持续作物脱颖而出,有可能解决粮食不安全和营养不良问题。这些小种子,抗旱谷物已经适应了广泛的非生物胁迫。研究人员热衷于阐明使小米能够承受环境逆境的监管机制。目的是通过基因工程或育种利用来自小米的这些鉴定的遗传决定因子来增强主要谷物作物的胁迫耐受性。这篇综述揭示了转录因子(TFs),这些转录因子控制着不同的非生物胁迫反应,并在赋予小米对各种非生物胁迫的耐受性中发挥作用。具体来说,研究了来自不同家族的TFs的分子功能和表达模式,包括bHLH,bZIP,DREB,HSF,MYB,NAC,NF-Y和WRKY,进行了全面的讨论。它还探讨了TFs在开发耐胁迫作物中的潜力,全面讨论了不同的整合策略。
