Special Issue Information

Dear Colleagues,

Potato, Solanum tuberosum L., is the leading vegetable crop in the world, and is important for global food security. However, potato is highly susceptible to two major abiotic stresses, heat stress and drought, which affect plant growth, development, and productivity, as well as tuber nutritive and processing qualities. Due to global climate change and the continuous rise in the Earth’s surface temperatures, the detrimental effects of heat and drought on potato are increasing. Recently, research efforts have been intensifying towards understanding the mechanisms associated with potato responses to high temperatures and/or water deficit that may lead to the development of new, tolerant potato varieties.

This Special Issue of Plants aims to provide an overview of current research and knowledge regarding potato heat and drought tolerance. We are pleased to invite researchers to submit papers that highlight potato physiological, biochemical, and molecular responses to heat and/or drought, genetic bases and mechanisms relevant to stress management, effects of biostimulants and plant elicitors, achievements by conventional and molecular breeding in the creation of tolerant genotypes, and other topics relevant to potato heat and/or drought tolerance. Submissions of original research articles, reviews, minireviews, and short communications are welcome.

Plants is pleased to announce a call for papers for a Special Issue that will comprise selected and extended plant-related papers that will be presented during the 4th International Conference on Plant Biology (23rd SPPS Meeting). The Conference will be held from 6–8 October 2022 in Belgrade, Serbia (http://www.dfbs.org.rs/en/welcome-message-from-the-organizing-commitee/). Contributors are welcome to submit original Special-Issue-related research and review articles on the topics covered during the meeting. Accepted manuscripts will receive a 20% discount on the article processing charge.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Most cultivated potatoes are tetraploid, and the tuber is the main economic part that is consumed due to its calorific and nutritional values. Recent trends in climate change led to the frequent occurrence of heat and drought stress in major potato-growing regions worldwide. The optimum temperature for tuber production is 15–20 °C. High-temperature and water-deficient conditions during the growing season result in several morphological, physiological, biochemical, and molecular alterations. The morphological changes under stress conditions may affect the process of stolon formation, tuberization, and bulking, ultimately affecting the tuber yield. This condition also affects the physiological responses, including an imbalance in the allocation of photoassimilates, respiration, water use efficiency, transpiration, carbon partitioning, and the source–sink relationship. The biochemical responses under stress conditions involve maintaining ionic homeostasis, synthesizing heat shock proteins, achieving osmolyte balance, and generating reactive oxygen species, ultimately affecting various biochemical pathways. Different networks that include both gene regulation and transcription factors are involved at the molecular level due to the combination of hot and water-deficient conditions. This article attempts to present an integrative content of physio-biochemical and molecular responses under the combined effects of heat and drought, prominent factors in climate change. Taking into account all of these aspects and responses, there is an immediate need for comprehensive screening of germplasm and the application of appropriate approaches and tactics to produce potato cultivars that perform well under drought and in heat-affected areas.
