“…These findings might suggest new research directions to investigate the molecular mechanisms of chickpea Fusarium wilt resistance. These downstream mechanisms are still being elucidated through transcriptomics and metabolomics approaches, implicating the expression of antifungal metabolites, reactive oxidative species, cell-wall remodeling, and the salicylic acid signaling pathway [ 12 , 13 , 51 , 52 , 53 , 54 ], which can also be race-specific [ 55 ].…”

Chickpea (Cicer arietinum) is a major food legume providing high quality nutrition, especially in developing regions. Chickpea wilt (Fusarium oxysporum f. sp. ciceris) causes significant annual losses. Integrated disease management of Fusarium wilt is supported by resistant varieties. Relatively few resistance genes are known so there is value in exploring genetic resources in chickpea wild relatives. This study investigates the inheritance of Fusarium wilt resistance (race 2) in recombinant inbred lines (RILs) from a cross between a cultivated susceptible chickpea variety (Gokce) and a wild resistant Cicer reticulatum line (Kayat-077). RILs, parents, resistant and susceptible tester lines were twice grown in the greenhouse with inoculation and disease symptoms scored. DNA was extracted from dried leaves and individuals were single nucleotide polymorphism (SNP) genotyped. SNPs were placed on the reference chickpea genome and quantitative trait locus (QTL) mapping was performed. Significant QTL regions were examined using PulseDB to identify candidate genes. The results showed the segregation of Fusarium wilt resistance conforming to a single gene inheritance. One significant QTL was found at the start of chromosome 8, containing 138 genes, three of which were disease-resistance candidates for chickpea breeding.

Thaumatin‐like proteins (TLPs) are conserved proteins involved in the defense and stress responses of plants. Previous studies showed that several TLPs were accumulated in leaf apoplast in Ammopiptanthus mongolicus in winter, indicating that TLPs might be related to the adaptation to winter climate in A. mongolicus. To investigate the roles of TLPs in winter adaptation, we first analyzed the expression pattern of TLP genes in A. mongolicus and then focused on the biological function and regulation pathway of AmTLP25 gene. Several TLP genes, including AmTLP25, were upregulated during winter and in response to both cold and osmotic stress. Overexpression of the AmTLP25 gene led to an increased tolerance of transgenic Arabidopsis to freezing and osmotic stress. Furthermore, the elevated AmWRKY14 transcription factor during winter activated AmTLP25 gene expression by specifically binding to its promoter. It is speculated that the AmWRKY14 – AmTLP25 module contributes to the adaptation to temperate winter climate in A. mongolicus. Our research advances the current understanding of the biological function and regulatory pathway of TLP genes and provides valuable information for understanding the molecular mechanism of temperate evergreen broad‐leaved plants adapting to winter climate.
