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 کاملGuard-cell signalling for hydrogen peroxide and abscisic acid.
Guard cells can integrate and process multiple complex signals from the environment and respond by opening and closing stomata in order to adapt to the environmental signal. Over the past several years, considerable research progress has been made in our understanding of the role of reactive oxygen species (ROS) as essential signal molecules that mediate abscisic acid (ABA)-induced stomatal clo...

متن کاملAbscisic acid-induced hydrogen peroxide is required for anthocyanin accumulation in leaves of rice seedlings.
The role of hydrogen peroxide (H(2)O(2)) in abscisic acid (ABA)-induced anthocyanin accumulation in detached and intact leaves of rice seedlings was investigated. Treatment with ABA resulted in an accumulation of anthocyanins in detached rice leaves. Dimethylthiourea, a chemical trap for H(2)O(2), was observed to be effective in inhibiting ABA-induced accumulation of anthocyanins. Inhibitors of...
