Tomato 26S Proteasome subunit RPT4a regulates ToLCNDV transcription and activates hypersensitive response in tomato
Involvement of 26S proteasomal subunits in plant pathogen-interactions, and the roles of each subunit in independently modulating the activity of many intra- and inter-cellular regulators controlling physiological and defense responses of a plant were well reported. In this regard, we aimed to functionally characterize a Solanum lycopersicum 26S proteasomal subunit RPT4a (SlRPT4) gene, which wa...
متن کاملIntestinal dipeptide hydrolase activities in undernourished children.
Kumar, V., Ghai, 0. P., and Chase, H. P. (1971). Archives of Disease in Childhood, 46, 801. Intestinal dipeptide hydrolase activities in undernourished children. Intestinal dipeptide hydrolase enzymes cleave dipeptides into amino acids. In 8 undernourished children with diarrhoea, mean intestinal mucosal glyclyl-proline hydrolase activity was reduced 40%, valyl-proline hydrolase activity 38%, a...
متن کاملProfiling serine hydrolase activities in complex proteomes.
Serine hydrolases represent one of the largest and most diverse families of enzymes in higher eukaryotes, comprising numerous proteases, lipases, esterases, and amidases. The activities of many serine hydrolases are tightly regulated by posttranslational mechanisms, limiting the suitability of standard genomics and proteomics methods for the functional characterization of these enzymes. To faci...
متن کاملComparisons of Peptide hydrolase activities in cereals.
Carboxypeptidase activity (hydrolysis of N-carbobenzoxy-l-phenylalanyl-l-alanine) is high in a number of temperate zone cereals, originating in Asia Minor (wheat, barley, oats, wild oats, rye, triticale) compared to other cereals originating in central America or Asia (maize, sorghum, rice). However, endopeptidase activity (hydrolysis of azocasein or hemoglobin) is relatively much higher in the...
متن کاملAbscisic 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...
