Abstract

The present study was carried out for the development of the water stress wheat cultivars with higher grain yield by studying the genetic basis of crucial morphological traits. Nine wheat genotypes were grouped into six lines and three testers and these parents were crossed line x tester fashion.

Key words: Cyanide ion, Methyl violet, Scanometry, Color space.

Abstract

In this study, the application of new and simple single drop scanometric method was described for determination of cyanide as alternative for visible spectrophotometric method. Cyanide ion reacts with the methyl violet and causes a decrease in the color intensity of solution.

Key words: Improved rice genotypes, Stem borers, Infestations, Deadhearts.

Abstract

Globally, rice production is limited by abiotic and biotic factors. Of the insect pests attacking rice, the stalk-eyed fly is the most abundant. Major rice growing districts in Uganda are affected, and varieties grown by farmers are susceptible. The objective of this study was to identify sources of resistance to stalk-eyed flies among improved rice genotypes in Uganda.

Keywords: NaCl stress, root proteome, two-dimensional electrophoresis, wheat.

Abstract

Salinity is the most important abiotic stress that adversely affects the quality and quantity of crops, in which 20% of the world’s irrigated agricultural lands are affected by salinity. Wheat is the oldest and the first crop used for bread making for human nutrition. To investigate the response of wheat root to NaCl stress, a susceptible, Arta, and resistance, Bam, wheat varieties were grown under both non-stress and stress conditions. Stress plants were exposed to 250 mM of NaCl based on a completely randomized design with four replications. Proteins were extracted from root and proteomic analysis was performed by two-dimensional polyacrylamide gel electrophoresis. Proteome profile of root in susceptible variety lead to the identification of 21 differentially changed protein spots compare with 49 spots of tolerant variety. The regulatory changed proteins belong to stress-responsive proteins and others related processes including metabolism and energy; scavenging of reactive oxygen species and detoxifying; protein translation, processing and degradation; cell wall-related proteins; Amino acid metabolism and hormone-related proteins; signal transduction network; cytoskeleton; transcription-related proteins.
