Dear Colleagues,

Postharvest fruits and vegetables are susceptible to suffering various abiotic stresses during transportation and processing, including temperature stress, light stress, air pollution, chemical contamination, mechanical injury, etc. Just like normal growing plants, when they encounter stress during growth, it will cause a series of changes in metabolic pathways and subsequently lead to various physiological and biochemical changes. Among them, secondary metabolism plays an important role in the process of resisting abiotic stresses. Therefore, regulating secondary metabolism is one of the most useful areas of study in terms of the postharvest quality and storage periods of postharvest fruits and vegetables as well as normal fruits and vegetables.

The objective of this Special Issue is to highlight the different innovative findings regarding postharvest fruit and vegetable preservation, food nutrition control, changes in the physiological metabolism of fruits and vegetables, and the regulatory mechanisms of secondary metabolism through collating selected publications on developments related to postharvest fruits and vegetables concerning scientific theories, agriculture, and food science. On this basis, the changes in secondary metabolite modification genes, such as glycosyltransferase, which can regulate the homeostasis of small molecules after suffering from stress, can be analyzed. We hope that this Special Issue will provide new perspectives for an improved understanding of the metabolic physiological regulation of postharvest fruits and vegetables.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.
