Cold-adapted yeasts were isolated from soil samples collected in Tibet and evaluated as potential biocontrol agents against blue mold (Penicillium expansum) of pear fruit in cold storage. YC1, an isolate identified as Rhodotorula mucilaginosa, was found to exhibit the greatest biocontrol activity among the different isolates that were screened. A washed cell suspension of YC1 exhibited the best biocontrol activity among three different preparations that were used in the current study. A concentration of 10(8) cells/ml reduced the incidence of decay to 35 %, compared to the control where decay incidence was 100 %. A higher intracellular level of trehalose and a higher proportion of polyunsaturated acids present in YC1, was associated with increased the tolerance of this strain to low temperatures, relative to the other strains that were evaluated. The increased tolerance to low temperature allowed the YC1 strain of yeast to more effectively compete for nutrients and space in wounded pear fruit that had been inoculated with spores of P. expansum and placed in cold storage. The present study demonstrated the ability to select cold-adapted yeasts from cold climates and use them as biocontrol agents of postharvest diseases of fruit placed in cold storage.

“…In the fructose and mannose metabolism, as well as glycolysis/gluconeogenesis pathways, the 6-phosphofructokinase 1 (PFK1) coordinating the photosynthetic carbon flow into sucrose and starch biosynthesis [ 71 ] was upregulated in Pvgstu3–3.4 under DT at 48 h. Another enzyme involved not only in glycolysis/gluconeogenesis but also in pyruvate metabolism responsible for increased pyruvate is pyruvate kinase, which was increased in Pvgstu3–3.4 line under combined DT treatment. Pyruvate kinase has been found to be increased during mild stress [ 72 ] and during heat stress in fungus Metarhizium robertsii as the first line of defense [ 73 ]. The conversion of pyruvate to acetyl-CoA in the chloroplasts is the start of the fatty acid biosynthesis, such as Triacylglycerol (TAG), which are linked to plant stress response (Lu et al 2020).…”

Drought and heat stresses are major factors limiting crop growth and productivity, and their effect is more devastating when occurring concurrently. Plant glutathione transferases (GSTs) are differentially expressed in response to different stimuli, conferring tolerance to a wide range of abiotic stresses. GSTs from drought-tolerant Phaseolus vulgaris var. “Plake Megalosperma Prespon” is expected to play an important role in the response mechanisms to combined and single heat and drought stresses. Herein, we examined wild-type N. tabacum plants (cv. Basmas Xanthi) and T1 transgenic lines overexpressing the stress-induced Pvgstu3–3 and Pvgstu2–2 genes. The overexpression of Pvgstu3–3 contributed to potential thermotolerance and greater plant performance under combined stress. Significant alterations in the primary metabolism were observed in the transgenic plants between combined stress and stress-free conditions. Stress-responsive differentially expressed genes (DEGs) and transcription factors (TFs) related to photosynthesis, signal transduction, starch and sucrose metabolism, osmotic adjustment and thermotolerance, were identified under combined stress. In contrast, induction of certain DEGs and TF families under stress-free conditions indicated that transgenic plants were in a primed state. The overexpression of the Pvgstu3–3 is playing a leading role in the production of signaling molecules, induction of specific metabolites and activation of the protective mechanisms for enhanced protection against combined abiotic stresses in tobacco.

“…Cold stress or low-temperature stress, classified as chiling stress (0-15°C) (Wang et al 2016) and freezing stress (<0°C) (Trischuk et al 2006), is another important abiotic stress which hinders the metabolic processes in plants which affects the growth and development and reduces the yield as well as the quality of vegetable crops (Ding et al 2019). Vegetable crops grown in tropical and subtropical climates experience serious freezing injury, even the freezing conditions prevail for a short duration.…”

Vegetables are an important component of human nutrition that encompasses great species diversity and are very sensitive to unpredictable climatic changes. In recent decades, there has been an increase in the frequency of events like drought, flooding, high-temperature, low temperature, salinity and changes of atmospheric CO2 or ozone level which considerably affect morphological, physiological and biochemical changes in the plants. The occurrences of these types of abiotic stresses lead to membrane damage, oxidative burst, reduction of chlorophyll content and photosynthesis rate which ultimately affect the yield and quality of vegetable crops. The adoption of appropriate crop management practices and climate-resilient cultivars would help immensely in dealing with the adverse impacts of abiotic stresses. Alteration in planting dates, advanced irrigation technology, moisture-saving methods, use of plant growth regulators, use of plant growth promoting rhizobacteria, grafting technology, use of climate resilient cultivars and protected cultivation-like management practices can reduce the impact and intensity of abiotic stress enhance the production as well. Overall in this review, we have summarized the adverse effects of abiotic stresses that are induced by climate change and management strategies that enable to overcome the ill effects and sustain the production of vegetable crops.
