“…The molecular-genetic mechanisms underpinning the bean-anthracnose interaction are poorly understood, despite the mapping of numerous host resistance (R) genes and quantitative trait loci (QTL) controlling resistance [11, 30]. Differential gene expression between the compatible and incompatible interaction was reported by Fraire-Velazquez and Lozoya-Gloria [31], where the putative phenylalanine ammonia lyase ( PAL ) and chalcone synthase ( CHS ) genes were identified as up-regulated in resistant bean lines.…”

Bean (Phaseolus vulgaris) anthracnose caused by the hemi-biotrophic pathogen Colletotrichum lindemuthianum is a major factor limiting production worldwide. Although sources of resistance have been identified and characterized, the early molecular events in the host-pathogen interface have not been investigated. In the current study, we conducted a comprehensive transcriptome analysis using Illumina sequencing of two near isogenic lines (NILs) differing for the presence of the Co-1 gene on chromosome Pv01 during a time course following infection with race 73 of C. lindemuthianum. From this, we identified 3,250 significantly differentially expressed genes (DEGs) within and between the NILs over the time course of infection. During the biotrophic phase the majority of DEGs were up regulated in the susceptible NIL, whereas more DEGs were up-regulated in the resistant NIL during the necrotrophic phase. Various defense related genes, such as those encoding PR proteins, peroxidases, lipoxygenases were up regulated in the resistant NIL. Conversely, genes encoding sugar transporters were up-regulated in the susceptible NIL during the later stages of infection. Additionally, numerous transcription factors (TFs) and candidate genes within the vicinity of the Co-1 locus were differentially expressed, suggesting a global reprogramming of gene expression in and around the Co-1 locus. Through this analysis, we reduced the previous number of candidate genes reported at the Co-1 locus from eight to three. These results suggest the dynamic nature of P. vulgaris–C. lindemuthianum interaction at the transcriptomic level and reflect the role of both pathogen and effector triggered immunity on changes in plant gene expression.

“…In Himachal Pradesh, bean anthracnose is of common recurrence with wide pathogenic and molecular variability (Sharma et al 1994(Sharma et al , 1999Padder et al 2007Padder et al , 2008Sharma et al 2007) and local cultivars are susceptible to one or the other race of the pathogen (Kumar et al 1997;Pathania et al 2006). The pathogen causes losses both in terms of yield and quality in dry and vegetable type of bean (Pastor-Corrales and Tu 1989;Sharma et al 2008).…”

Bean anthracnose caused by Colletotrichum lindemuthianum is a serious seed borne disease. For devising an effective management strategy, the efficacy of different bioagents, viz. Trichoderma viride, Trichoderma harzianum, Trichoderma hamatum and Gliocladium virens conducted under in vitro and in vivo conditions revealed maximum inhibition of mycelial growth in dual culture (59.48%) and inverted plate (55.98%) with T. viride. All the bioagents overgrew the pathogen and the principal mechanism of mycoparisitism observed was coiling, brusting and disintegration of pathogen hyphae. Culture filtrate from T. viride was found best as it completely inhibited radial growth at 25 and 50% concentration and reduced the spore germination of test fungus significantly. However, lower concentrations of culture filtrate from all bioagents showed little effect on spore germination. Seed application of bioagents was found better as compared to soil application. A maximum increase in seed germination and inhibition of seed borne infection was observed with T. viride followed by T. harzianum under pot culture conditions. T. viride has the maximum potentiality to suppress the spore germination, mycelial growth, seed borne infection of C. lindemuthianum and increased seed germination when compared with the other biocontrol agents.

“…In India, most of the work on BCMV has been conducted in Himachal Pradesh, a North-western Himalayan state, where evaluations of over 100 virus isolates (unpublished data) have only revealed the presence of BCMV (Sharma et al 1999;Sharma 2000;Kapil et al 2005). Wide variation exists in the common bean gene pool in India which has not so far been exploited as compared to Andean and Mesoamerican bean gene pools (Pathania et al 2006). The phenotypic recombination of BCMNV and BCMV strains (Silbernagel et al 2001) indicates the likely appearance of more complex disease problems caused by these viruses in the future.…”

Evaluation of 397 common bean accessions of diverse origin revealed the presence of eVective sources of resistance against bean common mosaic potyvirus strains prevalent in Himachal Pradesh, a north-western Himalayan state of India. 21 accessions viz., KR 7, KR 225, KR 295, KRC 4, KRC 7, KRC 11, KRC 12, KRC 13, KRC 16, KRC 22, Amanda, Black Turtle Soup, Contender, Hans, Great Northern UI 123, Improved Tender Green 40031, Jubila, Kentucky wonder, Monroe, Premier and Sanilac, were found resistant to NL-1n and NL-7n strains. Some of the genotypes showed strain speciWc resistance. Pattern of inheritance studied in Hans, Contender, KRC 4 and KRC 22 of Indian origin against strain NL-1n revealed that single dominant gene governed the resistance in Hans and Contender whereas single recessive gene determined the resistance in KRC 22 and KRC 4. SCAR marker SW13 690 ampliWed a product of 690 bp in Hans and Contender, conWrmed the presence of I gene in these cultivars. The implications of above genes in breeding for programme for BCMV resistance are discussed.
