Abscisic acid enhances resistance to Alternaria solani in tomato seedlings.
The plant hormone abscisic acid (ABA) is an important regulator in many aspects of plant growth and development, as well as stress resistance. Here, we investigated the effects of exogenous ABA application on the interaction between tomato (Solanum lycopersicon L.) and Alternaria solani (early blight). Foliar spraying of 7.58 μM ABA was effective in reducing disease severity in tomato plants. P...
متن کاملEffect of Some Essential Oils for Limiting Early Blight (alternaria Solani) Development in Potato Field
The fungicidal effect of some essential oils against Alternaria solani one of the species that cause early blight of potato was evaluated under in vitro and field conditions. Effect of carnation, caraway, thyme oils and the chemical fungicide Ridomil MZ 72 at various concentrations on mycelial growth of A. solani was tested. Carnation oil had the strongest and most extensive inhibitory effect o...
متن کاملCurrent Status of Early Blight Resistance in Tomato: An Update
Early blight (EB) is one of the dreadful diseases of tomato caused by several species of Alternaria including Alternaria linariae (which includes A. solani and A. tomatophila), as well as A. alternata. In some instances, annual economic yield losses due to EB have been estimated at 79%. Alternaria are known only to reproduce asexually, but a highly-virulent isolate has the potential to overcome...
متن کاملMicroarray analyses during early stage of the tomato/Alternaria solani interaction.
Tomato early blight is an important threat and it has capacity to reduce the production in all major tomato producing areas. Molecular mechanism underlying the resistance against this is not well known. Therefore we studied this system to search the possible mechanism of resistance, which includes pathogenesis related protein, and pathways and transcription factors, which are responsible for re...
متن کاملgenetic diversity of alternaria alternata causal agent of early blight of tomato in khuzestan province using ssrs marker
introduction: the early blight of tomato caused by alternaria alternata is one of the most important and destructive diseases in khuzestan province. study genetic structure of a. alternata populations provides different levels of information in the management of early blight disease in tomato farms. short sequence repeat (ssr) markers were used to determine the genetic structure and estimate ge...
