Abstract

Vitamin C, also referred to as ascorbic acid (AsA), is recognized for its capacity to cure and avert scurvy, and it is crucial for regular human growth and development. In various crops, AsA participates in stress response mechanisms mediated by abscisic acid and has been discovered to have a crucial function in the morphogenesis, growth, development, and production of male gametes in plants. GDP-D-mannose 3′,5′-epimerase (GME) is essential in the synthesis of vitamin C. Our research identified 91, 83, 51, and 46 genes, respectively, found in G. barbadense (GbGMEs), G. hirsutum (GhGMEs), G. arboretum (GaGMEs), and G. raimondii (GrGMEs). Plants resulting from VIGS infection with GhGME31D clearly showed yellowing, water loss and wilting of leaves and black spots on stems. Measurement of MDA and AsA levels indicated that the plants were more damaged. This indicates that AsA has a substantial impact on plant growth and development.

从 GME 基因家族对棉花碱胁迫的影响中发现 GhGME31D 可调控 AsA 的激活

维生素 C 又称抗坏血酸（AsA），因其能够治疗和避免坏血病而被公认，对人体的正常生长和发育也至关重要。在各种作物中，AsA 参与脱落酸介导的应激反应机制，并被发现在植物的形态发生、生长、发育和雄性配子的产生中具有重要功能。我们的研究发现，在 G. barbadense（GbGMEs）、G. hirsutum（GhGMEs）、G. arboretum（GaGMEs）和 G. raimondii（GrGMEs）中分别发现了 91、83、51 和 46 个基因。VIGS 感染 GhGME31D 后的植株明显出现叶片变黄、失水和枯萎，茎上出现黑斑。MDA 和 AsA 水平的测量结果表明，植物受到的损害更大。这表明 AsA 对植物的生长和发育有很大影响。

期刊介绍： ESEU is an international journal, focusing primarily on Europe, with a broad scope covering all aspects of environmental sciences, including the main topic regulation. ESEU will discuss the entanglement between environmental sciences and regulation because, in recent years, there have been misunderstandings and even disagreement between stakeholders in these two areas. ESEU will help to improve the comprehension of issues between environmental sciences and regulation. ESEU will be an outlet from the German-speaking (DACH) countries to Europe and an inlet from Europe to the DACH countries regarding environmental sciences and regulation. Moreover, ESEU will facilitate the exchange of ideas and interaction between Europe and the DACH countries regarding environmental regulatory issues. Although Europe is at the center of ESEU, the journal will not exclude the rest of the world, because regulatory issues pertaining to environmental sciences can be fully seen only from a global perspective.
