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...

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...

Assessment of Tri- and Hexavalent Chromium Phytotoxicity on Oats (Avena sativa L.) Biomass and Content of Nitrogen Compounds

The purpose of this study was to determine the effect of soil contamination with tri- and hexavalent chromium and soil application of compost, zeolite, and CaO on the mass of oats and content of nitrogen compounds in different organs of oats. The oats mass and content of nitrogen compounds in the crop depended on the type and dose of chromium and alleviating substances incorporated to soil. In ...
