Abstract
Environmental stresses have major impacts on the morphological, physiological, and biochemical processes of plants. Among these stresses, drought is the major one which greatly restricts crop productivity globally. When challenged by drought, plants promote the expression of ABA biosynthesis genes which results in ABA accumulation. Increase in ABA level promotes stomatal closure to increase plant’s adaptative response to drought stress. To handle and restrain the negative impact of drought stress, it is important to understand how plants respond to drought and the involvement of ABA in plant adaptation to drought stress at a molecular level. Under drought stress, ABA biosynthesis is the most significant event to protect plants from the dehydration stress. ABA biosynthesis is a complicated process that is mainly regulated by ABA biosynthetic enzymes. This review highlights the recent advancements in ABA biosynthesis and its involvement in plant adaptation to drought stress to improve their growth and development under water-deficient conditions.
环境胁迫对植物的形态、生理和生化过程有重大影响。在这些胁迫中，干旱是严重制约全球作物生产力的主要胁迫。面对干旱的挑战，植物会促进 ABA 生物合成基因的表达，从而导致 ABA 的积累。ABA 水平的提高会促进气孔关闭，从而增强植物对干旱胁迫的适应性反应。为了应对和抑制干旱胁迫的负面影响，了解植物如何应对干旱以及 ABA 在分子水平上参与植物对干旱胁迫的适应非常重要。在干旱胁迫下，ABA 的生物合成是保护植物免受脱水胁迫的最重要事件。ABA 生物合成是一个复杂的过程，主要由 ABA 生物合成酶调控。本综述重点介绍 ABA 生物合成的最新进展及其在植物适应干旱胁迫过程中的参与，以改善植物在缺水条件下的生长和发育。
期刊介绍：
Journal of Plant Biology, an official publication of the Botanical Society of Korea, is an international journal devoted to basic researches in biochemistry, cellular biology, development, ecology, genetics, molecular biology, physiology, and systematics of plants.
The Journal publishes the following categories of paper:
Original articles -- For publication in Journal of Plant Biology the manuscript must provide a significant new contribution to our understanding of plants. All areas of plant biology are welcome. No limit on the length, but a concise presentation is encouraged.
Reviews -- Invited by the EiC.
Brief Communications -- Concise but independent report representing significant contribution to plant science.
The Botanical Society of Korea was founded on November 30, 1957 to promote studies, disseminate and exchange information on the field of plant biology. The first issue of The Korean Journal of Botany, the official publication of the society, was published on April 1, 1958. It was published twice a year, but quarterly from 5th volume in 1962. In 1994, it was renamed to Journal of Plant Biology and published in English since 1996. The journal entered its 50th year of publication in 2007.
