Historical contingencies modulate the adaptability of Rice yellow mottle virus.

PLoS Pathogens, 2012
The rymv1-2 and rymv1-3 alleles of the RYMV1 resistance to Rice yellow mottle virus (RYMV), coded by an eIF(iso)4G1 gene, occur in a few cultivars of the Asiatic (Oryza sativa) and African (O. glaberrima) rice species, respectively.

Fine mapping of two grain chalkiness QTLs sensitive to high temperature in rice

Rice, 2021
Background Grain chalkiness is one of important factors affected rice grain quality. It is known that chalkiness is affected by the high temperature during the seed filling period.

Allele mining unlocks the identification of RYMV resistance genes and alleles in African cultivated rice

BMC Plant Biology, 2020
Background Rice yellow mottle virus (RYMV) is a major rice pathogen in Africa. Three resistance genes, i.e. RYMV1, RYMV2 and RYMV3, have been previously described.

Genetic Diversity and Phenotypic Variation in an Introgression Line Population Derived from an Interspecific Cross between Oryza glaberrima and Oryza sativa. [PDF]

PLoS ONE, 2016
The introduction of closely related species genomic fragments is an effective way to enrich genetic diversity and creates new germplasms in crops. Here, we studied the genetic diversity of an introgression line (IL) population composed of 106 ILs derived

Oryza sativa cv. Nipponbare and Oryza barthii as Unexpected Tolerance and Susceptibility Sources Against Schizotetranychus oryzae (Acari: Tetranychidae) Mite Infestation

Frontiers in Plant Science, 2021
Cultivated rice (Oryza sativa L.) is frequently exposed to multiple stresses, including Schizotetranychus oryzae mite infestation. Rice domestication has narrowed the genetic diversity of the species, leading to a wide susceptibility.

Morpho-agronomic evaluation of Oryza glaberrima accessions and interspecific O. sativa × O. glaberrima derived lines under drought conditions

AFRICAN JOURNAL OF AGRICULTURAL RESEEARCH, 2012
Two dry-season field experiments were conducted at AfricaRice research station in Benin to identify drought tolerant rice genotypes from a range of genetic resources: in 2006 using 202 backcross-inbred interspecificOryza sativa ´ Oryza glaberrima lines, replicated in 2007 (experiment 1); and in 2007 (replicated in 2008) using a population of 327 ...

Are Brazilian bamboo species helpful for cognition and memory?

Phytomedicine Plus, 2022
Background: Bamboo species has been used for centuries in Asian traditional medicine to treat mental disorders resulting from the aging process. Brazil has the greatest diversity of bamboos in the Americas, with a high degree of endemism, but just a few ...

A Recessive Resistance to Rice yellow mottle virus Is Associated with a Rice Homolog of the CPR5 Gene, a Regulator of Active Defense Mechanisms

Molecular Plant-Microbe Interactions, 2013
RYMV2 is a major recessive resistance gene identified in cultivated African rice (Oryza glaberrima) which confers high resistance to the Rice yellow mottle virus (RYMV).

Endophytes from African Rice (Oryza glaberrima L.) Efficiently Colonize Asian Rice (Oryza sativa L.) Stimulating the Activity of Its Antioxidant Enzymes and Increasing the Content of Nitrogen, Carbon, and Chlorophyll

Microorganisms, 2021
Bacterial endophytes support the adaptation of host plants to harsh environments. In this study, culturable bacterial endophytes were isolated from the African rice Oryza glaberrima L., which is well-adapted to grow with poor external inputs in the ...

PlantGFM: A Genomic Foundation Model for Discovery and Creation of Plant Genes

Advanced Science, EarlyView.
A plant genomic foundation model pre‐trained on 12 species enables both accurate gene prediction and de novo gene design. Through AI‐human knowledge screening, seven designed sequences showed transcriptional activity in plants, with two expressing stable proteins—demonstrating the first DNA‐RNA‐protein expression of LLM‐generated genes in plants and ...
