Abstract

Fleshy Fruit (FF) ripening is regulated by multiple hormones, which can be categorized into two groups, i.e., the positive signals acting to promote FF ripening and the negative signals acting to suppress FF ripening. Ethylene (ET) and abscisic acid (ABA) are two predominant positive signals respectively controlling climacteric (CL) and non-climacteric (NC) FF ripening, whereas auxin (IAA) is the predominant negative signal controlling both FF growth and ripening. Functioning of these hormones is initiated by an alteration of the hormonal levels, which is referred to as the process of Hormonal Signal Production (HSP) in FF development and ripening. While the hormonal regulation of FF ripening has been extensively studied and reviewed, knowledge of HSP has never been summarized and discussed. The purpose of this review is to summarize and discuss the triggering mechanism of HSP. We first summarize the physiological, biochemical and molecular bases of HSP for three crucial hormones, ET, ABA, and IAA, including hormonal metabolism, transport and reciprocal regulation of HSP among different hormones, we then summarize and discuss the recent discoveries on the mechanism of cellular signal transduction of HSP. Finally, we propose several viewpoints to facilitate comprehension of the future research endeavors.

肉质果实成熟过程中显性激素信号产生的触发机制。

肉质果实（Fleshy Fruit， FF）成熟受多种激素调控，可分为促进FF成熟的积极信号和抑制FF成熟的消极信号两类。乙烯（ET）和脱落酸（ABA）分别是控制FF成熟期（CL）和非成熟期（NC）成熟的主要正信号，而生长素（IAA）是控制FF生长和成熟的主要负信号。这些激素的功能是由激素水平的改变启动的，这被称为FF发育和成熟过程中的激素信号产生（HSP）过程。虽然激素对FF成熟的调控已经被广泛的研究和回顾，但关于热休克蛋白的知识从未被总结和讨论过。本文就HSP的触发机制进行综述和探讨。本文首先综述了热休克蛋白对三种关键激素ET、ABA和IAA的生理生化和分子基础，包括热休克蛋白在不同激素之间的激素代谢、转运和相互调节，然后总结和讨论了热休克蛋白细胞信号转导机制的最新发现。最后，我们提出了几个观点，以促进对未来研究工作的理解。

期刊介绍： Aims Molecular Horticulture aims to publish research and review articles that significantly advance our knowledge in understanding how the horticultural crops or their parts operate mechanistically. Articles should have profound impacts not only in terms of high citation number or the like, but more importantly on the direction of the horticultural research field. Scope Molecular Horticulture publishes original Research Articles, Letters, and Reviews on novel discoveries on the following, but not limited to, aspects of horticultural plants (including medicinal plants): ▪ Developmental and evolutionary biology ▪ Physiology, biochemistry and cell biology ▪ Plant-microbe and plant-environment interactions ▪ Genetics and epigenetics ▪ Molecular breeding and biotechnology ▪ Secondary metabolism and synthetic biology ▪ Multi-omics dealing with data sets of genome, transcriptome, proteome, metabolome, epigenome and/or microbiome. The journal also welcomes research articles using model plants that reveal mechanisms and/or principles readily applicable to horticultural plants, translational research articles involving application of basic knowledge (including those of model plants) to the horticultural crops, novel Methods and Resources of broad interest. In addition, the journal publishes Editorial, News and View, and Commentary and Perspective on current, significant events and topics in global horticultural fields with international interests.
