Rice BRITTLE CULM 5 (BRITTLE NODE) is Involved in Secondary Cell Wall Formation in the Sclerenchyma Tissue of Nodes
Several brittle culm (bc) mutants known in grasses are considered excellent materials to study the process of secondary cell wall formation. The brittle phenotype of the rice bc5 (brittle node) mutant appears exclusively in the developed nodes, which is distinct from other bc mutants (bc1, 2, 3, 4, 6 and 7) that show the brittle phenotype in culms and leaves. To address the defects of the rice ...
متن کاملCharacterization of an a-Amylase with Broad Temperature Activity from an Acid-Neutralizing Bacillus cereus Strain
Bacillus sp. GUF8, isolated from acidic soil samples of a tea farm was identified as Bacillus cereus, based on 16S rDNA sequencing and standard bacterial identification methods. Following optimization of enzyme production, the resulting α-amylase was purified by acetone precipitation and ion exchange chromatography. Consequently, thermostability and kinetic parameters of the purified enzyme wer...
متن کاملEffect of Heat Stress on Amylase Activity in Chalky and Translucent Rice Genotypes
Occurrence of chalkiness is a major problem as it is an important parameter in determining the quality of rice grains. High temperature during the grain filling period results in loose packing starch granules that could be due to the involvement of starch degrading enzymes i.e., amylases. Therefore, two rice genotypes viz., PAU 3699-13-2-1-1 and PR122 were sown at two different dates. Thirty-da...
متن کاملAmylase inhibitory activity of some macrolichens in Mazandaran province, Iran
Introduction: α-amylase is a major form of amylase found in humans and other mammals. It is the special key enzyme involved in carbohydrates breakdown. Inhibition of this enzyme could be used in treatment of diabetes. In this study, the effect of ten Iranian macrolichens on alpha amylase were tested. Methods: Different concentrations of the extracts (25, 50 and 75 mg/ml) were incubated wi...
متن کاملAmylase activity in human bile.
The mean amylase level in 42 human bile samples was 154 IU/l and there was no significant difference in the amylase activity of 32 paired serum and bile samples. Estimation of the amylase thermolability of bile showed it to be similar to that of serum. This suggests that the amylase activity in bile may have filtered through the liver from the hepatic circulation rather than refluxed from the p...
