In evaluating the germination and growth of seed resources 322 cultivars cowpea (Vigna unguiculata), we found development yellow symptoms on ~50% cotyledons 10 cultivars. RNA-Seq analysis total RNA extracted from symptomatic indicated that were infected with bean common mosaic virus (Potyvirus phaseovulgaris, BCMV), which is a member family Potyviridae able to seed-transmit progeny plants. One BCMV isolates identified in was BCMV(Vu06), cultivar #6. During BCMV(Vu06)-infected plants, there no systemic newly developing leaves, but coat protein detected both leaves flowers. Thus, #6 plant latently BCMV(Vu06). There significant difference dry matter weight above-ground parts between BCMV(Vu06)-latently non-infected However, plants had late flower bud formation longer life slightly lower yield than The 1,000-seed frequency seeds harvested same as those Taken together, latent infection BCMV(Vu6) modulates balance vegetative reproductive lifespan may provide an advantage for its survivability over generations. BCMV(Vu06) might have established mutual symbiotic relationship during their interaction.
