El virus rayado fino del maíz en Venezuela [Zea mays]

Maize rayado fino virus (MRFV) was isolated in Venezuela from plants showing dwarfing and parallel leaf stripes along the veins. The virus particles are isometric with 33 um in diameter and became separated in two bands by sucrose density gradient which indicates that there are differences in their...

Se aisló el virus rayado fino del maiz (MRFV) en Venezuela, de plantas que mostraban enanismo y rayas paralelas a lo largo de las nervaduras de las hojas. Se encontró que las particulas del virus son isométricas, de 33 um de diámetro, y se les separó en dos bandas por medio del gradiente de densidad de la sacarosa, lo que indica que tienen diferencias en sus contenidos de úcido nucléico. El virus reaccionó positivamente contra el antisuero preparado con MRFV de Costa Rica y virus rayado fino colombiano de maiz (MRFCV). Se observó una transmisión persistente del virus mediante Dalbulus maidis y el hecho de que Peregrinus maidis no fue capaz de transmitir la enfermedad. Se encontraron partículas del virus en el citoplasma y vacuolas de secciones de células infectadas. La enfermedad parece prevalecer en altitudes de 400 m en Venezuela, en contraste con Costa Rica y Colombia donde se ha manifestado sobre los 1000 m 2023-10-23T16:24:37Z 2023-10-23T16:24:37Z 1980-10 Artículo https://repositorio.catie.ac.cr/handle/11554/12294 openAccess en Turrialba; Vol. 30, no. 4 4 páginas application/pdf Instituto Interamericano de Cooperación para la Agricultura (IICA)
