Identification of potential hosts plants of Cowpea aphid‐borne mosaic virus

Abstract

Brazil is the world's largest producer and consumer of passion fruit, with a plantation area of approximately 41,000 hectares and a production of 554,000 tons. The major states producing the fruit are Bahia, Ceará and Santa Catarina, with a production of approximately 170,000, 94,000 and 46,000 tons, respectively. Paraná is the eighth largest passion fruit producer in Brazil and is responsible for 3.6% of the national production that amounts to a revenue of 49.5 million reais (IBGE, 2017). Currently, one of the major phytosanitary issues associated with passion fruit crop production is the virus infestation that causes the hardening of the fruits. This disease is a limiting factor for the cultivation of the species in certain regions (Damatto

Characterization of Cucurbit Aphid-Borne Yellows Virus (CABYV) from Passion Fruit in Brazil: Evidence of a Complex of Species within CABYV Isolates

“…Both viruses have a wide range of host plants and can infect cultivated and non-cultivated plants of diverse plant families. CABMV can infect plants of the families Passifloraceae, Fabaceae, Cucurbitaceae, Solanaceae, Chenopodiaceae, Amaranthaceae, and Poaceae [ 50 , 51 , 52 , 53 ]. CABYV has a wide range of Cucurbitacea plants as hosts and can infect several other plant families, such as Brassicaceae, Asteraceae, Malvaceae, Fabaceae, Amaranthaceae, Chenopodiaceae, Papaveraceae, Lamiaceae, Portulacaceae, Solanaceae, and Passifloraceae [ 16 , 17 , 20 , 27 , 32 , 54 , 55 , 56 , 57 , 58 ].…”

Partial efficacy of early and temporary roguing to manage woodiness disease in pilot crops of passion fruit

“…None of the A. viridis , A. hybridus , A. spinosus , L. sibiricus or C. echinatus plants grown among CABMV‐infected passion fruit plants in Capivari, SP, was found to be naturally infected with CABMV, although A . viridis , L. sibiricus , C. echinatus and C. spectabilis were recently reported as potential hosts for an isolate of CABMV in the state of Paraná, when inoculated mechanically (Junco et al, 2021). The authors recommended that plants of these four species be removed from the neighbourhood of passion fruit orchards as they might act as CABMV inoculum source.…”

“…Therefore, we hypothesized that passion fruit plants, after the latent period of CABMV infection but before symptom expression (incubation period), could emit attractive olfactory cues for aphids present in the area. Aphids acquire CABMV (Junco et al, 2021).…”

“…In addition to plants of different Passiflora species, CABMV naturally infects other plants of families Fabaceae ( Arachis hypogea , Canavalia ensiformes , Canavalia rosea , Cassia hoffmannseggii , Crotalaria juncea , Desmodium sp., Glycine max , Phaseolus lunatus , Phaseolus vulgaris , Senna occidentalis and Vigna unguiculata ), Pedaliaceae ( Sesamum indicum ) and Acanthaceae ( Thunbergia alata ) (Kitajima, 2020). Junco et al (2021) reported experimental transmission of CABMV to slender amaranth ( Amaranthus viridis ), Siberian motherwort ( Leonurus sibiricus ), showy rattlepod ( Crotalaria spectabilis ) and southern sandbur ( Cenchrus echinatus ) and suggested that these species may serve as primary sources of virus inoculum in the field. No field or experimental evidence is available regarding the importance of these plants in the epidemiology of passion fruit woodiness disease in Brazil.…”

Infectivity Assays for Soybean and Cowpea Mosaic Viruses and Their Management

“…Morphologically, it consists of long elongated particles of length 670-750nm and diameter 12-15nm (Hesketh et al, 2017). The singlestranded RNA molecules that are positive sense are found in their genome of nearly 10,000 nucleotides (Junco et al, 2021). The viruses of potyviridae family destroy the parenchymatous cells and mechanically transmittable by infected plant extract (Banerjee et al, 2014).…”
