Detection of Drechslera avenae (Eidam) Sharif [Helminthosporium avenae (Eidam)] in Black Oat Seeds (Avena strigosa Schreb) Using Multispectral Imaging. [PDF]

Sensors (Basel), 2020
Conventional methods for detecting seed-borne fungi are laborious and time-consuming, requiring specialized analysts for characterization of pathogenic fungi on seed. Multispectral imaging (MSI) combined with machine vision was used as an alternative method to detect Drechslera avenae (Eidam) Sharif [Helminthosporium avenae (Eidam)] in black oat seeds (

Participation of Wild Species Genus Avena L. (Poaceae) of Different Ploidy in the Origin of Cultivated Species According to Data on Intragenomic Polymorphism of the ITS1-5.8S rRNA Region [PDF]

Plants
The possible origin of four cultivated species of the genus Avena of different ploidy and different subgenome composition (A. strigosa, A. abyssinica, A. byzantina, and A. sativa) from possible wild species was investigated.

Subtelomeric assembly of a multi-gene pathway for antimicrobial defense compounds in cereals [PDF]

Nature Communications, 2021
The genomic organization and origin of the avenacin biosynthetic gene cluster remain unknown. Here, the authors assemble the genome of diploid oat Avena strigosa, reveal the structure and organization of the consecutive genes, characterize the last two ...

A multilevel exploration of Avena strigosa diversity as a prelude to promote alternative crop. [PDF]

BMC Plant Biol, 2019
Sand oat (Avena strigosa Schreb.), one of the four cultivated species of the genus Avena, could be considered as another alternative crop. In gene banks 865 germplasm samples of this species have been preserved that have not been thoroughly investigated so far.

Mapping crown rust resistance in the oat diploid accession PI 258731 (Avena strigosa). [PDF]

PLoS One
Oat crown rust, caused by Puccinia coronata Corda f. sp. avenae Eriks. (Pca), is a major biotic impediment to global oat production. Crown rust resistance has been described in oat diploid species A. strigosa accession PI 258731 and resistance from this accession has been successfully introgressed into hexaploid A. sativa germplasm.

High-quality genome of allotetraploid Avena barbata provides insights into the origin and evolution of B subgenome in Avena. [PDF]

J Integr Plant Biol
A high‐quality genome sequence of the tetraploid wild oat Avena barbata provides crucial genetic information for the Avena B‐genome, allowing clarification of the evolutionary trajectories of the four subgenomes within Avena and identification of numerous key genes related to environmental adaptability, thus offering valuable resources for oat breeding

Phosphate system fertilization in no-tillage Oxisols: Effects of temporal, horizontal, and vertical distribution of available phosphorus in the soil. [PDF]

J Environ Qual
Abstract System fertilization enhances logistics and phosphorus (P) use efficiency, but its effects in high P‐export systems, particularly regarding fertilization timing, placement, and distribution, remain unclear. This study evaluated P fertilization timing (90, 45, and 0 days before winter crop sowing [DBS]), placement (banded vs.

Genetic dissection of crown rust resistance in oat and the identification of key adult plant resistance genes. [PDF]

Plant Genome
Abstract Crown rust (Puccinia coronata f. sp. Avenae Erikss.) poses a significant threat to oat production worldwide. The most effective strategy for managing this disease involves identifying, mapping, and deploying resistance genes to develop cultivars with enhanced resistance.
