Purification, substrate specificity, and N-terminal amino acid sequence analysis of a beta-lactamase-free penicillin amidase from Alcaligenes sp.
(SPRINGER, 2004-08)A β-lactamase-free penicillin amidase from Alcaligenes sp. active against various β-lactams was purified to homogeneity. The enzyme can hydrolyze penicillin G to 6-amino penicillanic acid (6-APA) and furnish penicillin G ... -
Homodimeric Alkaline Phosphatase Located at Helicoverpa armigera Midgut, a Putative Receptor of Cry1Ac Contains alpha-GaINAc in Terminal Glycan Structure as Interactive Epitope
(AMER CHEMICAL SOC, 2009-04)Helicoverpa armigera causes massive yield loss of various crops globally. Bacillus thuringiensis coded Cry1Ac toxin is effective against the pest. Through the present investigation, an alkaline phosphatase type putative ... -
Effectiveness of garlic lectin on red spider mite of tea
(TAYLOR & FRANCIS LTD, 2008-09)Red spider mite (Oligonychus coffeae) is one of the major pests of tea and damages 5-15% of the total crop every year. Mannose binding 25 kDa lectins (ASAI, Allium sativum bulb agglutinin I and ASAII, A. sativum bulb ... -
Cre/lox system to develop selectable marker free transgenic tobacco plants conferring resistance against sap sucking homopteran insect
(SPRINGER, 2008-10)A binary expression vector was constructed containing the insecticidal gene Allium sativum leaf agglutinin (ASAL), and a selectable nptII marker gene cassette, flanked by lox sites. Similarly, another binary vector was ... -
A Molecular Insight into the Early Events of Chickpea (Cicer arietinum) and Fusarium oxysporum f. sp ciceri (Race 1) Interaction Through cDNA-AFLP Analysis
(AMER PHYTOPATHOLOGICAL SOC, 2009-11)Wilt of chickpea caused by Fusarium oxysporum f. sp. ciceris is one of the most severe diseases of chickpea throughout the world. Variability of pathotypes of F. oxysporum f. sp. ciceris and breakdown of natural resistance ... -
Tissue specific expression of potent insecticidal, Allium sativum leaf agglutinin (ASAL) in important pulse crop, chickpea (Cicer arietinum L.) to resist the phloem feeding Aphis craccivora
(SPRINGER, 2009-08)The phloem sap-sucking hemipteran insect, Aphis craccivora, commonly known as cowpea aphid, cause major yield loss of important food legume crop chickpea. Among different plant lectins Allium sativum leaf agglutinin (ASAL), ...
