However, the related studies on the potato OASTL gene family (StOASTL) have not been reported. In the present study, we identified 11 members of the StOASTL gene family, conducting a thorough analysis encompassing chromosome distribution, protein physicochemical properties, gene structure, protein-conserved motifs, and gene replication events.

Overexpression of in Potato Enhances Tolerance to Drought Stress.

Calcium-dependent protein kinases (CDPKs), which are activated by transient changes in the Ca concentration in plants, are important for various biological processes, such as growth, development, defense against biotic and abiotic stresses, and others. Mannitol is commonly used as an osmotic regulatory substance in culture medium or nutrient solutions to create water-deficit conditions. Here, we cloned the potato ( L.

Overexpression of Potato Gene in Tobacco Enhances the Transgenic Plant Tolerance to Drought Stress.

PYR/PYL/RCAR proteins are abscisic acid (ABA) receptors that play a crucial role in plant responses to abiotic stresses. However, there have been no research reports on potato PYL so far. In this study, a potato gene named was identified based on transcriptome data under drought stress.

The Truncated Peptide AtPEP1 Has the Same Function as AtPEP1 in Inhibiting Primary Root Growth and Triggering of ROS Burst.

Currently, the widely used active form of plant elicitor peptide 1 (PEP1) from is composed of 23 amino acids, hereafter AtPEP1, serving as an immune elicitor. The relatively less conserved N-terminal region in AtPEP family indicates that the amino acids in this region may be unrelated to the function and activity of AtPEP peptides. Consequently, we conducted an investigation to determine the necessity of the nonconserved amino acids in AtPEP1 peptide for its functional properties.

Thiamethoxam Application Improves Yield and Drought Resistance of Potatoes ( L.).

(1) Background: Potato is the most important tuber crop in the world that can contribute to food security. However, the crop has been shown to be sensitive to drought and its yields decline significantly during successive periods of stress. Drought triggers a number of responses in potato, ranging from physiological changes to fluctuations in growth rates and yields.

Comprehensive Characterization of the C3HC4 RING Finger Gene Family in Potato ( L.): Insights into Their Involvement in Anthocyanin Biosynthesis.

The C3HC4 RING finger gene (RING-HC) family is a zinc finger protein crucial to plant growth. However, there have been no studies on the RING-HC gene family in potato. In this study, 77 putative s were identified in the potato genome and grouped into three clusters based on phylogenetic relationships, the chromosome distribution, gene structure, conserved motif, gene duplication events, and synteny relationships, and -acting elements were systematically analyzed.

Foliar Application of Chelated Sugar Alcohol Calcium Improves Photosynthesis and Tuber Quality under Drought Stress in Potatoes ( L.).

Drought stress is a major threat to sustainable crop production worldwide. Despite the positive role of calcium (Ca) in improving plant drought tolerance in different crops, little attention has been paid to its role in mitigating drought stress in potatoes. In the present study, we studied the effect of foliar chelated sugar alcohol calcium treatments on two potato cultivars with different drought responses applied 15 and 30 days after limiting soil moisture.

Integrated transcriptomic and metabolomic analysis revealed altitude-related regulatory mechanisms on flavonoid accumulation in potato tubers.

Not least because it is adaptable to a variety of geographies and climates, potato (Solanum tuberosum L.) is grown across much of the world. Pigmented potato tubers have been found to contain large quantities of flavonoids, which have various functional roles and act as antioxidants in the human diet.

Evolutionary Analysis of Family Genes and Their Overexpression in Transgenic Tobacco Improve Drought Tolerance.

Sucrose non-ferment 1-related protein kinase 2 (SnRK2) is a highly conserved protein kinase in plants that plays an important role in regulating plant response to drought stress. Although it has been reported in some plants, the evolutionary relationship of potato SnRK2s and their function in drought resistance have not been systematically analyzed. In this study, molecular characteristic analysis showed that 8 StSnRK2s were distributed on six chromosomes, coding proteins were divided into three subgroups, and StSnRK2s clustered in the same subgroup had similar conserved motifs and domains.
