Tomato (Solanum lycopersicum) is considered an important crop, but local producers face difficulties in choosing the appropriate variety due to its diversity and ecological adaptability. In effort provide alternative option of varieties selection suitable varieties, this research was conducted evaluate comparative performance sixteen tomato (11 AVRDC lines, five check varieties) at Tangaro, Cat...

The defense response to several abiotic stresses has been compared in two tomato inbred lines issued from the same breeding program, one susceptible and the other resistant to Tomato yellow leaf curl virus (TYLCV) infection. The level of oxidative burst and the amounts of key regulatory stress proteins: pathogenesis-related proteins (PRs), heat shock proteins (HSPs) and mitogen-activated protei...

A variety of fresh market vegetables, including watermelon and tomato are economically important crops in Florida. Whitefly-transmitted Squash vein yellowing virus (SqVYV) was first identified in squash and watermelon in Florida in 2005 and shown to cause a severe decline of watermelon vines as crops approach harvest. Florida is most economically impacted by SqVYV, although the virus has been d...

The present work reveals the beneficial role of sodium nitroprusside (SNP; NO donor concentration: 50 and 100 µM) in mitigation water stress accompanied by a reduction viral disease incidence tomato plants subjected to deficit irrigation. were grown under two irrigation regimes: well-watered (WW; irrigated after depletion 55–60% available soil water) (WD; 85–90% seasons 2018 2019. results indic...

A functional capsid protein (CP) is essential for host plant infection and insect transmission in monopartite geminiviruses. We studied two defective genomic DNAs of tomato yellow leaf curl virus (TYLCV), Sic and SicRcv. Sic, cloned from a field-infected tomato, was not infectious, whereas SicRcv, which spontaneously originated from Sic, was infectious but not whitefly transmissible. A single a...
