چکیده
Abstract: The objective of this work was to evaluate the inheritance resistance Cowpea aphid-borne mosaic virus (CABMV) in cowpea (Vigna unguiculata). study performed between parental genotypes IT85F-2687 (resistant) and 'BR-14 Mulato' (susceptible), generating F1, F2, F7 populations backcrosses with both genotypes. CABMV inoculated on plants from all generations, which were then evaluated through visual inspection description characteristic symptoms. A chi-square test after phenotypic classification plants. segregation proportion 1:3 (resistant:susceptible) population F2 1:1 accepted, showing a recessive monogenic inheritance.

RT-PCR Detection of Seedborne Cowpea aphid-borne mosaic virus in Peanut
In 1995, Cowpea aphid-borne mosaic virus (CABMV) of the family Potyviridae was reported to infect peanut (Arachis hypogaea L.) in Brazil (6). Leaf symptoms consisted of ring spots and blotches, and virus incidence was high when peanut was intercropped with cowpea (Vigna unguiculata (L.) Walp. subsp. unguiculata). CABMV was seed transmitted at approximately 0.15% in peanut and 6% in cowpea (6) a...
متن کاملRhizobacteria-mediated resistance against the blackeye cowpea mosaic strain of bean common mosaic virus in cowpea (Vigna unguiculata).
BACKGROUND The present study investigated the effect of seven Bacillus-species plant-growth-promoting rhizobacteria (PGPR) seed treatments on the induction of disease resistance in cowpea against mosaic disease caused by the blackeye cowpea mosaic strain of bean common mosaic virus (BCMV). RESULTS Initially, although all PGPR strains recorded significant enhancement of seed germination and se...
متن کاملNext-Generation Sequencing Reveals the First Complete Genome Sequence of Cowpea aphid-borne mosaic virus from Uganda
We present here the first complete genome sequence of Cowpea aphid-borne mosaic virus (CABMV) isolated from cowpea in Uganda and compare it with five CABMV complete genome sequences from Brazil (2), India (2), and Zimbabwe (1). It most resembled the genomes of two Brazilian isolates (MG-Avr and BR1) and one Indian isolate (RR3).
متن کاملRNAi-derived transgenic resistance to Mungbean yellow mosaic India virus in cowpea
Cowpea is an important grain legume crop of Africa, Latin America, and Southeast Asia. Leaf curl and golden mosaic diseases caused by Mungbean yellow mosaic India virus (MYMIV) have emerged as most devastating viral diseases of cowpea in Southeast Asia. In this study, we employed RNA interference (RNAi) strategy to control cowpea-infecting MYMIV. For this, we generated transgenic cowpea plants ...
متن کاملIsolation and characterization of tubular structures of cowpea mosaic virus.
Tubular structures involved in the cell-to-cell movement of cowpea mosaic virus (CPMV) were partially purified from infected cowpea protoplasts to identify the structural components. A relatively pure fraction could be obtained by differential centrifugation and this was analysed by PAGE and immunoblotting. Besides the movement protein (MP) and capsid proteins (CP) of CPMV, no other major infec...
