Special Issue Information

Dear Colleagues,

The potato is the fourth largest food crop in the world after wheat, rice and corn. It has rich nutritional value, high yield and strong adaptability. However, with the increase in extreme weather throughout the world, potato cultivation is faced with nutrient stress, drought, high temperature, low temperature and heavy metal and other abiotic or biological stresses. At the same time, the inappropriate storage of tubers will reduce the breeding rate of seed potatoes and the value of commercial potatoes. Therefore, it is necessary to study the physiological and molecular biological mechanism of the potato in response to abiotic stress and tuber storage. This Special Issue welcomes research on the physiology, molecular aspects and genetics of potato cultivation and storage, including fertilizer utilization, nutrient stress, abiotic stress and biotic stress response, the safe storage of tubers, postharvest physiology, etc.

Sucrose phosphate synthase (SPS), a crucial rate-limiting enzyme that catalyzes the synthesis of precursors of sucrose, plays an indispensable role in the regulation of seed potato vigor. Nonetheless, the genes that encode SPS in potato have not undergone complete analysis, and the primary genes responsible for the regulation of seed potato vigor have not been screened and identified. In this study, four StSPS family members were identified by comparing the potato genome database with homologous proteins. Using bioinformatics, the physicochemical properties, subcellular localization, sequence structure, conserved motifs, and phylogenetics of StSPS were analyzed. The expression levels of StSPS in different potato tissues, from dormancy to sprouting in the seed potato tubers, were measured via qRT-PCR. The expression data from the potato genome database and previous transcriptome and proteome studies of dormancy to sprouting were also compared. After combining the analysis of SPS enzyme activity in diverse tuber tissues and the correlation analysis between multiple varieties with different dormancy periods and the expression of StSPS1, the primary gene StSPS1 that might regulate seed potato vigor was identified. This study set a theoretical and experimental groundwork for further verification and clarification of the regulatory function of StSPS1 in alterations in seed potato vigor. Full article

With the intensifying global warming trend, extreme heat and drought are becoming more frequent, seriously impacting potato yield and quality. To maintain sustainable potato production, it is necessary to breed new potato varieties that are adaptable to environmental changes and tolerant to adversity. Despite its importance, there is a significant gap in research focused on the potential mechanisms of potato resistance to abiotic stresses like drought and high temperatures. This article provides a comprehensive review of the recent research available in academic databases according to subject keywords about potato drought tolerance and high temperature tolerance with a view to providing an important theoretical basis for the study of potato stress mechanism and the selection and breeding of potato varieties with drought and high-temperature resistance. The suitable relative soil moisture content for potato growth and development is 55% to 85%, and the suitable temperature is 15 °C to 25 °C. The growth and development of potato plants under drought and high-temperature stress conditions are inhibited, and plant morphology is altered, which affects the process of potato stolon formation, tuberization and expansion, ultimately leading to a significant reduction in potato tuber yields and a remarkable degradation of the market grade of tubers, the specific gravity of tubers, and the processing quality of tubers. In addition, stress also adversely affects potato physiological and biochemical characteristics, such as reduction in root diameter and leaf area, decrease in net photosynthetic rate of leaves, production of reactive oxygen species (ROS), and increase in membrane lipid peroxidation. In addition, various types of genes and transcription factors are involved in the response to drought and heat at the molecular level in potato. This paper illustrates the effects of stress on potato growth and development and the molecular mechanisms of potato response to adversity in detail, which is intended to reduce the damage caused by drought and high temperature to potato in the context of global warming and frequent occurrence of extreme weather to ensure potato yield and quality and to further safeguard food security.
