“…Heat-shock protein genes like HSP17.7 [ 18 ] and Heat Shock Cognate 70 are reported to confer heat tolerance in potatoes [ 19 , 20 ]. Transcription factors like CAPSICUM ANNUUM PATHOGEN FREEZING TOLERANCE PROTEIN 1 ( CaPF1 ) [ 21 ], C-REPEAT BINDING FACTOR 1 ( CBF3 ) [ 22 ], and ETHYLENE RESPONSE FACTOR ( StERF94 ) [ 23 ] have been associated with heat tolerance in potatoes through transgenic studies. Certain genes, such as SELF PRUNING 6A ( StSP6A ), TERMINAL FLOWER-1 ( StTFL1 ), POTATO HOMEODOMAIN 1 ( StPOTH1 ), BEL1-LIKE PROTEIN ( StBEL5 ), micro-RNA ( miR172 ), POTATO MADS BOX 1 ( POTM1 ), CYCLING DOF FACTOR ( StCDF ), STIP1 HOMOLOGY AND U-BOX CONTAINING PROTEIN ( StTUB19 and StTUB7 ), ABA RESPONSIVE ELEMENT(ABRE) BINDING FACTOR ( StABF2 and StABF4 ), have been identified as positive regulators of tuberization and are potential candidates for overexpression to confer heat tolerance in potato clones.…”

Heat stress during the potato growing season reduces tuber marketable yield and quality. Tuber quality deterioration includes external (heat sprouts, chained tubers, knobs) and internal (vascular discoloration, hollow heart, internal heat necrosis) tuber defects, as well as a reduction in their specific gravity and increases in reducing sugars that result in suboptimal (darker) processed products (french fries and chips). Successfully cultivating potatoes under heat-stress conditions requires planting heat-tolerant varieties that can produce high yields of marketable tubers, few external and internal tuber defects, high specific gravity, and low reducing sugars (in the case of processing potatoes). Heat tolerance is a complex trait, and understanding its genetic basis will aid in developing heat-tolerant potato varieties. A panel of 217 diverse potato clones was evaluated for yield and quality attributes in Dalhart (2019 and 2020) and Springlake (2020 and 2021), Texas, and genotyped with the Infinium 22 K V3 Potato Array. A genome-wide association study was performed to identify genomic regions associated with heat-tolerance traits using the GWASpoly package. Quantitative trait loci were identified on chromosomes 1, 3, 4, 6, 8, and 11 for external defects and on chromosomes 1, 2, 3, 10, and 11 for internal defects. Yield-related quantitative trait loci were detected on chromosomes 1, 6, and 10 pertaining to the average tuber weight and tuber number per plant. Genomic-estimated breeding values were calculated using the StageWise package. Clones with low genomic-estimated breeding values for tuber defects were identified as donors of good traits to improve heat tolerance. The identified genomic regions associated with heat-tolerance attributes and the genomic-estimated breeding values will be helpful to develop new potato cultivars with enhanced heat tolerance in potatoes.

“…Zhao et al [ 10 ] reported that NAC , MYB , WRKY , homeobox-leucine zipper ( HD-ZIP ) and basic leucine-zipper ( bZIP ) were closely related to the response to PEG osmotic stress in Jerusalem artichoke. In potato, Charfeddine et al [ 17 ] revealed that overexpression of StERF94 improved the tolerance of transgenic plants to drought, heat, and combined stresses. However, the DEGs and responding mechanism of kohlrabi under water deficit induced by osmotic stress have not been reported.…”

Osmotic stress is a condition in which plants do not get enough water due to changes in environmental factors. Plant response to osmotic stress is a complex process involving the interaction of different stress-sensitive mechanisms. Differentially expressed genes and response mechanisms of kohlrabi have not been reported under osmotic stress. A total of 196,642 unigenes and 33,040 differentially expressed unigenes were identified in kohlrabi seedlings under polyethylene glycol osmotic stress. AP2/ERF, NAC and eight other transcription factor family members with a high degree of interaction with CAT and SOD antioxidant enzyme activity were identified. Subsequently, 151 AP2/ERF genes were identified and analyzed. Twelve conserved motifs were searched and all AP2/ERF genes were clustered into four groups. A total of 149 AP2/ERF genes were randomly distributed on the chromosome, and relative expression level analysis showed that BocAP2/ERF genes of kohlrabi have obvious specificity in different tissues. This study lays a foundation for explaining the osmotic stress resistance mechanism of kohlrabi and provides a theoretical basis for the functional analysis of BocAP2/ERF transcription factor family members.
