Calcium ion (Ca2+) is a ubiquitous second messenger that transmits various internal and external signals including stresses and, therefore, is important for plants' response process. Calcineurin B-like proteins (CBLs) are one of the plant calcium sensors, which sense and convey the changes in cytosolic Ca2+-concentration for response process. A search in(More)
Nerium indicum [Family:Apocynaceae] is commonly known as Arali [Tam] found throughout India, and has been used in the treatment of cancer, cardiotonic, leprosy and skin diseases. Plant parts such as root, bark and leaves are used. The present study is therefore undertaken to analyse its phyto chemical constituents in solvents like Benene, Chloroform and(More)
Calcium signaling plays an important role in adaptation and developmental processes in plants and animals. A class of calcium sensors, known as Calcineurin B-like (CBL) proteins sense specific temporal changes in cytosolic Ca(2+) concentration and regulate activities of a group of ser/thr protein kinases called CBL-interacting protein kinases (CIPKs).(More)
Numerous plants and fungi produce mannitol, which may serve as an osmolyte or metabolic store; furthermore, mannitol also acts as a powerful quencher of reactive oxygen species (ROS). Some phytopathogenic fungi use mannitol to stifle ROS-mediated plant resistance. Mannitol is essential in pathogenesis to balance cell reinforcements produced by both plants(More)
In the present study, we have evaluated the comparative biochemical defense response generated against Alternaria alternata and its purified toxins viz. alternariol (AOH), alternariol monomethyl ether (AME), and tenuazonic acid (TeA). The necrotic lesions developed due to treatment with toxins were almost similar as those produced by the pathogen,(More)
