“…Although the plants had not been inoculated, several studies reveal that the high levels of identity with CABMV observed in the Brazilian isolates suggested that most PWD cases reported in Brazilian passion fruit were caused by CABMV, (Nascimento et al, 2006;Pinto et al, 2008;Cerqueira-Silva et al, 2008;Nicolini et al, 2012;Santos et al, 2015a;Carvalho, 2019) thus implicating CABMV as the cause of the disease and consequent economic losses in Brazil.…”

The woodiness disease induced by the Cowpea aphidborne mosaic virus (CABMV) is regarded as a limiting factor for passion fruit production. We estimated genetic parameters for resistance and agronomic performance-related traits and selected genotypes resistant to CABMV in segregating populations of passion fruit. The experiment was a randomized-block design with four replicates, consisting of six full-sibling first backcross genotype families, in which 319 genotypes were evaluated. The disease symptoms were evaluated based on spontaneous occurrence of CABMV, using a scale of scores in young leaves, plant and fruits. Based on these scores, we estimated the area under the disease progress curve (MAUDPC). Agronomic traits were also assessed: fruit weight per plant and number of fruits per plant. The variance components and genetic value of each genotype were estimated for each variable via mixed models. The MAUDPC values ranged from 401.25 to 1192.5, indicating considerable genetic variability. The high individual narrow-sense heritability value for the MAUDPC trait (0.95) indicates the possibility of genotypic selection within CABMV-resistant families. For the production-related traits, even ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 20 (1): gmr18668 S.C. Preisigke et al. 2 with low heritability values, it was possible to obtain genetic gains in individual selection, which ranged from 4.99 to 6.24% for fruit weight and 22.64 to 28.70% for number of fruits. The genotypes chosen to compose the next backcross generation should be selected based on resistance to CABMV, which is the main objective of the program, since agronomic traits can be recovered from backcrosses. Of the 30 individuals ranked for CABMV tolerance, genotypes 501, 506, and 597 were selected to compose the next generation of backcrosses. These had the lowest values for MAUDPC.

“…and common bean (Phaseolus vulgaris L.), have been reported. Those with the most predominance in the field are cucumber mosaic virus (CMV) (Eiras et al 2004), cowpea aphid-borne mosaic virus (CABMV) (Nicolini et al 2012), cowpea severe mosaic virus (CPSMV) (Abreu et al 2012) and cowpea mild mottle virus (CPMMV) (Lamas et al 2017). There are, however, few reports of viruses infecting lima bean (Carvalho et al 2015), possibly because lima bean is mainly cultivated by small farmers and has less economic importance than cowpea and common bean.…”

Lima bean plants showing mosaic and leaf distortion symptoms, similar to those induced by viruses, were observed in several production areas in the states of Ceará and Piauí, Northeastern Brazil. The aim of this study was to identify RNA genome viruses that infect lima bean. Field research was conducted from 2017 to 2018. Fifty-five symptomatic samples were randomly collected from seven properties in five municipalities and tested by RT-PCR and DNA sequencing with specific or universal primers for two viruses and two virus groups. Four virus species were identified: cucumber mosaic virus (CMV), cowpea mild mottle virus (CPMMV), cowpea aphid-borne mosaic virus (CABMV) and cowpea severe mosaic virus (CPSMV), which had infection levels of 21.8, 52.7, 47.2, and 1.8%, respectively, as well as double and triple infections. The CMV isolates belonged to subgroup IA. The CPMMV isolates had high nucleotide identity with CPMMV isolates from Brazil, USA and Mexico. The CABMV isolates showed moderate nucleotide identity with Brazilian isolates. Only one sample was infected with CPSMV. This is the first record of CPMMV and CPSMV naturally infecting lima bean. Approaches to virus control are discussed.

“…Passion fruit is a fruit crop cultured in Brazil, that is also affected by virus diseases which have adversely affected its production and expansion (FISCHER;KIMATI;RESENDE, 2005;NICOLINI et al, 2012). Several virus species have already been identified causing disease on passion fruit in Brazil and species from the genus Potyvirus have been considered to be responsible for the most important problems (LIMA et al, 2015;MACIEL et al, 2009).…”

-P a s s i on f r u i t ( Passiflora edulis) and cowpea (Vigna unguiculata) are two agricultural crops of considerable economic importance in Northeastern Brazil. Fruit woodiness caused by isolates of Cowpea aphid-borne mosaic virus biotype P (CABMV-P) is the most important virus disease that occurs on passion fruit in Brazil and the biotype cowpea (CABMV-C) is responsible for the most common and important virus disease of cowpea in Northeastern Brazil. The objective of the present research was to determine the biological relationships between isolates of biotype CABMV-C obtained from cowpea (CABMV-CFor and CABMV-CBv) and isolates of biotype CABMV-P obtained from passion fruit (CABMV-PMild and CABMV-PSevere) in common hosts. In host range studies involving 25 plant species only Canavalia ensiformis and Macroptilium lathyroides were shown to be common systemic hosts for all virus isolates. Cross protection studies were developed between CABMV-PMild and CABMV-PSevere in passion fruit and between CABMV-PSevere and CABMV-CFor in C. ensiformis. Unilateral cross protection was detected between CABMVPSevere and CABMV-CFor in C. ensiformis, but CABMV-PMild did not cross protect passion fruit against CABMVPSevere.
