Grain quality and status of oats (Avena sativa L.) during storage

The Spectrum of Major Seed Storage Genes and Proteins in Oats (Avena sativa)

BACKGROUND The oat seed storage proteins are mainly composed of two classes: the globulins and avenins. Among the major cereals, the globulins are the major seed protein class in rice and oats, and along with the higher protein content of oats is the basis for the relative higher nutrition content in oats compared to the other cereals. The second major class of oat seed proteins is the avenins;...

Identification of Oats (Avena sativa L.) Cultivars by Seed and Seedling Protein Electrophoresis

Soluble proteins were extracted from seed and seedlings of eleven oats cultivars to analyze the protein profile through SDS PAGE method. In seed protein electrophoresis totally 14 bands were observed, in these six bands were common to all cultivars. Based on the seed protein banding pattern two of these cultivars were differentiated easily. The unique band at Rf value 0.151 was common for all c...

Chiasma frequency, distribution and terminalization in hexaploid oats (Avena sativa L.)

Chiasma counting has been regarded as the most straightforward method of scoring the total number of crossing-over events in the genome. In organisms in which genetic analysis is difficult or impossible to perform, it is a good estimator of the level of genetic recombination. In this paper we evaluated the chiasma frequency and distribution at diakinesis of twelve Brazilian oat varieties (Avena...

Subcellular Localization of Proteases in Developing Leaves of Oats (Avena sativa L.).

The distribution and subcellular localization of the two major proteases present in oat (Avena sativa L. cv Victory) leaves was investigated. Both the acidic protease, active at pH 4.5, and the neutral protease, active at pH 7.5, are soluble enzymes; a few percent of the enzyme activity was ionically bound or loosely associated with organellar structures sedimenting at 1000g. On the average, 16...
