Despite progress in identifying ABA-related genes and pathways, the complete ABA regulatory network underlying seed traits remains unclear. This review synthesizes ABA functions across developmental stages and seedling establishment, emphasizing the LAFL hub and multi-gene control by ABI3, ABI4, and ABI5. It also analyzes complex crosstalk between ABA and other phytohormones, highlighting key challenges and future directions for improving seed vigor and longevity.","Journal of Advanced Research 35 (2022) 199–214  \nContents lists available at ScienceDirect  \nJournal of Advanced Research  \njournal [homepage: www. elsevier. com/locate/jare](homepage: www. elsevier. com/locate/jare)  \nUpdated role of ABA in seed maturation, dormancy, and germination Faiza Ali a, 1,2, Ghulam Qanmber a, 1,2, Fuguang Li a,b,2, ⇑, Zhi Wang a,b,2, ⇑  \na Zhengzhou Research Base, State Key Laboratory of Cotton Biology, Zhengzhou University, Zhengzhou 450001, China  \nb State Key Laboratory of Cotton Biology, Institute of Cotton Research, Chinese Academy of Agricultural Sciences, Anyang 455000, China  \nh i g h l i g h t s  \n􀀁 Functional ABA biosynthesis genes show specific roles for ABA accumulation at different stages of seed development and seedling establishment.  \n􀀁 De novo ABA biosynthesis during embryogenesis is required for late seed development, maturation, and induction of primary dormancy.  \n􀀁 ABA plays multiple roles with the key LAFL hub to regulate various downstream signaling genes in seed and seedling development.  \n􀀁 Key ABA signaling genes ABI3, ABI4, and ABI5 play important multiple functions with various cofactors during seed development such as degreening, desiccation tolerance, maturation, dormancy, and seed vigor.  \n􀀁 The crosstalk between ABA and other phytohormones are complicated and important for seed development and seedling establishment.  \ng r a p h i c a l a b s t r a c t  \na r t i c l e i n f o  \nArticle history:  \nReceived 25 December 2020 Revised 3 March 2021  \nAccepted 27 March 2021  \nAvailable online 31 March 2021  \nKeywords: Phytohormones Embryogenesis Desiccation tolerance  \nSeed development, Seedling establishment  \na b s t r a c t  \nBackground: Seed is vital for plant survival and dispersion, however, its development and germination are influenced by various internal and external factors. Abscisic acid (ABA) is one of the most important phytohormones that influence seed development and germination. Until now, impressive progresses in ABA metabolism and signaling pathways during seed development and germination have been achieved. At the molecular level, ABA biosynthesis, degradation, and signaling genes were identified to play important roles in seed development and germination. Additionally, the crosstalk between ABA and other hormones such as gibberellins (GA), ethylene (ET), Brassinolide (BR), and auxin also play critical roles. Although these studies explored some actions and mechanisms by which ABA-related factors regulate seed morphogenesis, dormancy, and germination, the complete network of ABA in seed traits is still unclear.  \nAim of review: Presently, seed faces challenges in survival and viability. Due to the vital positive roles in dormancy induction and maintenance, as well as a vibrant negative role in the seed germination of ABA, there is  \nPeer review under responsibility of Cairo University.  \n⇑ Corresponding authors at: No. 38, Huanghedadao, Anyang 455000, China (F.
