Infection by Sugarcane yellow leaf virus (ScYLV) causes severe leaf symptoms in sugarcane (Saccharum spp.) hybrids, which indicate alterations in its photosynthetic apparatus. To gain an overview of the physiological status of infected plants, we evaluated chlorophyll a fluorescence and gas exchange assays, correlating the results with leaf metabolic surveys, i.e., photosynthetic pigments and carbohydrate contents. When compared to healthy plants, infected plants showed a reduction in potential quantum efficiency for photochemistry of photosystem (PSII) and alterations in the filling up of the plastoquinone (PQ) pool. They also showed reduction in the CO2 net exchange rates, probably as a consequence of impaired quantum yield. In addition, reductions were found in the contents of photosynthetic leaf pigments and in the ratio chlorophyll a/chlorophyll b (chla/chlb). Carbohydrate content in the leaves was increased as a secondary effect of the ScYLV infection. This article discusses the relation of virus replication and host defense responses with general alterations in the photosynthetic apparatus and in the metabolism of infected plants.

  La caña de azúcar es uno de los cultivos industriales importantes a nivel mundial y es afectado por diversas enfermedades virales, incluido el sugarcane yellow leaf virus (SCYLV). En México este virus se ha detectado basado en sintomatología y °Brix; sin embargo, el diagnóstico basado en estos parámetros no es concluyente. El objetivo del estudio fue detectar la presencia y distribución del SCYLV en zonas cañeras del Occidente de México (Colima, Jalisco y Nayarit) y determinar el origen filogenético de un aislado de Colima. El trabajo se desarrolló en el Campo Experimental Tecomán durante 2013-2014. Se aisló el RNA total a partir de hojas colectadas y se realizaron las RT-PCR con oligonucleótidos específicos para SCYLV. Se analizaron 233 muestras y la incidencia de plantas portadoras del SCYLV fue 14.6%, afectando a los híbridos CP 72-2086, Mex 69-290 y Atemex 96-40. El análisis BLAST mostró que la secuencia parcial CP de Colmex-317 (512 pb) es homóloga con secuencias de Brasil, China, India, Kenia y USA, además comparte porcentajes de identidad superior a 99% con otras secuencias provenientes de varios países. El análisis filogenético de Colmex-317 con secuencias parciales y genomas completos del SCYLV aislados de diversas partes del mundo reveló que el aislado mexicano pertenece al genotipo de Brasil (BRA) y se agrupó con secuencias de Brasil, China, Kenia y Sudáfrica. Sin embargo, es necesario evaluar un mayor número de aislados y secuencias de mayor longitud para determinar si el genotipo BRA es el único presente en México.
