Plant growth and phenolic compounds in the rhizosphere soil of wild oat (Avena fatua L.)
The objectives of this study were to determine the pattern of dry matter (DM) accumulation and the evolution of phenolic compounds in the rhizosphere soil from tillering to the ripe seed stages of wild oat (Avena fatua L.), a widespread annual grassy weed. Plants were grown under controlled conditions and harvested 13 times during the growing season. At each harvest, shoot and root DM and pheno...
متن کاملMechanisms of oat (Avena sativa L.) acclimation to phosphate deficiency
Background Deficiency of available forms of phosphorus is common in most soils and causes reduction of crop plants growth and yield. Recently, model plants responses to phosphate (Pi) deficiency have been intensively studied. However, acclimation mechanisms of cereals like oat (Avena sativa L.), to low Pi stress remains not fully understood. Oat plants have been usually cultured on poor soils, ...
متن کاملHormonal Regulation of alpha-Amylase Gene Transcription in Wild Oat (Avena fatua L.) Aleurone Protoplasts.
The time of appearance and relative amounts of alpha-amylase mRNA in wild oat (Avena fatua L.) aleurone protoplasts incubated with 1 micromolar gibberellin A(4) (GA(4)) were closely correlated with the amounts of alpha-amylase enzyme secreted by the protoplasts. In the absence of GA(4), or when protoplasts were incubated with 25 micromolar abscisic acid (ABA) together with 1 micromolar GA(4) no...
متن کاملA SNP genotyping array for hexaploid oat (Avena sativa L.)
Recognizing a need in cultivated hexaploid oat (Avena sativa L.) for a reliable set of reference SNPs, we have developed a 6K BeadChip design containing 257 Infinium I and 5,486 Infinium II Page 1 of 32 The Plant Genome Accepted paper, posted 06/19/2014. doi:10.3835/plantgenome2014.03.0010
متن کاملDiscrimination of the closely related A and D genomes of the hexaploid oat Avena sativa L.
A satellite DNA sequence, As120a, specific to the A-genome chromosomes in the hexaploid oat, Avena sativa L., was isolated by subcloning a fragment with internal tandem repeats from a plasmid, pAs120, that had been obtained from an Avena strigosa (As genome) genomic library. Southern and in situ hybridization showed that sequences with homology to sequences within pAs120 were dispersed througho...
