“…In northwestern Mexico the disease is diagnosed based on the plant's symptoms. Chickpea wilt has been detected in 60% of the soils of La Costa de Hermosillo, Sonora, while in Sinaloa losses of 20% have been recorded (Manjarrez-Sandoval et al, 2004) and losses of 10 to 90% have been reported for other countries (Landa et al, 2006;Sharma and Muehlbauer, 2007).…”

Problem statement:Mexico is the third largest producer and exporter of chickpea (Cicer arietinum), with the states of Sinaloa and Sonora accounting for 70 and 20% of Mexico's production, respectively. The most damaging disease affecting this species is caused by Fusarium oxysporum f.sp. Ciceris (FOC), which causes losses of up to 60% in Sonora. The objective of this study was to isolate and characterize the phenotype and genetics of FOC collected from affected chickpea plants in northwestern Mexico and to identify the abiotic factors that allow it to develop. Approach: Sampling focused on affected plants from 12 crops in Sonora and Sinaloa. Based on 355 isolated strains, using Polymerase Chain Reaction (PCR) 161 were positive for FOC. Results: Of the 161 strains, 91 were identified as races previously recorded for the Americas: Yellowing (R0 (41%), R1B/C (15%) and wilting (R5 (14%) and R6 (28%) reflecting the symptoms observed in the areas sampled. The other 70 isolates could be nonpathogenic, or could be races yet to be recorded for the Americas. Conclusion: Morphological variability in FOC was high in the main chickpea producing regions in northwestern Mexico and was not a function of the physical and chemical properties of the soil, nor of the geographic location of the cropfields. This is the first report of races of FOC in Mexico.

“…Ninety-four RILs out of total one hundred and twenty-five F 9 :F 10 RILs were randomly chosen to construct a molecular map and locate the QTLs associated with Fusarium wilt resistance. JG62 is an early wilting genotype highly susceptible to Foc races 1 to 5 (Sharma & Muehlbauer 2007), while WR315 is resistant to them. During the year 2010 plant materials were propagated in the glasshouse at UAS (Dharwad) and genomic DNA was isolated from young leaves as per the procedure of Doyle and Doyle (1990).…”

“…Later several studies on inter-and intraspecific recombinant inbred line (RIL) populations revealed that the resistance genes (foc1 and foc3, foc4 and foc5) against Fusarium wilt races 1, 3, 4 and 5 are organized in two adjacent resistance gene clusters on Linkage Group II (LG II). These two gene clusters are flanked by sequence-tagged microsatellite (STMS) markers GA16 and TA96 (foc1-foc4 cluster) and TA96 and TA27 (foc3-foc5 cluster), respectively (Winter et al 2000;Sharma & Muehlbauer 2007;Cobos et al 2009;Gowda et al 2009;Halila et al 2009). Halila et al (2009) located foc 0 2 /foc 0 2 in a region where genes for resistance to wilt races 1, 2, 3, 4 and 5 have previously been reported using data from two mapping populations (CA2139/JG62 and CA2156/JG62).…”

Patil B.S., Ravikumar R.L., Bhat J.S., Soregaon C.D. (2014): Molecular mapping of QTLs for resistance to early and late Fusarium wilt in chickpea. Czech J. Genet. Plant Breed., 50: 171-176.A molecular map of chickpea was constructed using F 9 :F 10 recombinant inbred lines from an intraspecific cross between Fusarium wilt susceptible (JG 62) and resistant (WR 315) genotypes. A total of 23 markers with LOD scores of > 3.0 were mapped on the recombinant inbred lines (RILs). Twenty sequence tagged microsatellites (STMSs) and three amplified fragment length polymorphisms (AFLPs) covered 300.2 cM in five linkage groups at an average inter-marker distance of 13 cM. Early and late wilting due to Fusarium infection was recorded in RILs at 30 and 60 DAS, respectively. There was a significant variation among RILs for wilt resistance for both early and late wilting. QTLs associated with early (30 days after sowing (DAS)) and late (60 DAS) wilting are located on LG II. The flanking markers for these QTLs were the same as those of previous reports. Five STMS markers located on LG II of reference map (interspecific) were mapped on LG II of the present map (intraspecific) with minor changes in the order of markers indicating the conservation of these genomic regions across the Cicer species.

“…In a different study, a candidate gene Ln controlling leaflet and seed number per pod was cloned with a combination of MBC and association study (Fang et al 2013). The cloning and characterisation of Fusarium wilt resistance genes using MBC was demonstrated for chickpea (Huettel et al 2002;Sharma and Muehlbauer 2007). Efforts are under way to clone genes from within a drought tolerance QTL region in chickpea (Thudi 2013).…”

“…In common bean, TorresFranklin et al (2008) cloned the gene glutathione reductase (dtGR), a drought stress-responsive gene. Other stress-related genes have been identified and cloned with the above approaches in crop legumes including soybean, chickpea and cowpea (Sharma and Muehlbauer 2007;França et al 2008;Fang et al 2013). Some examples are shown in Table 4.…”

Abstract. Legumes are important food crops worldwide, contributing to more than 33% of human dietary protein. The production of crop legumes is frequently impacted by abiotic and biotic stresses. It is therefore important to identify genes conferring resistance to biotic stresses and tolerance to abiotic stresses that can be used to both understand molecular mechanisms of plant response to the environment and to accelerate crop improvement. Recent advances in genomics offer a range of approaches such as the sequencing of genomes and transcriptomes, gene expression microarray as well as RNA-seq based gene expression profiling, and map-based cloning for the identification and isolation of biotic and abiotic stressresponsive genes in several crop legumes. These candidate stress associated genes should provide insights into the molecular mechanisms of stress tolerance and ultimately help to develop legume varieties with improved stress tolerance and productivity under adverse conditions. This review provides an overview on recent advances in the functional genomics of crop legumes that includes the discovery as well as validation of candidate genes.
