Genetic dissection and transcriptomic analysis of a novel high‐tillering phenotype in rice derived from weedy rice (Hapcheonaengmi3) and Tongil‐type Rice (Milyang23)

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Rice (Oryza sativa L.) tillering is a critical determinant of grain yield, yet the genetic mechanisms underlying non‐productive tillers remain poorly understood. Here, we report a novel high‐tillering (HT) phenotype derived from a cross between the elite cultivar Milyang23 and weedy rice Hapcheonaengmi3. The HT phenotype was absent in parental

Challenges in Bringing Pangenome Research Into Breeding: A Case Study in Rice

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3679-3690, June 2026.
ABSTRACT Crop breeding has entered the pangenomics era, unlocking a far more comprehensive view of genetic diversity than a single reference genome can capture. In rice (Oryza sativa), a staple crop critical to global food security, the construction of pangenome resources has uncovered extensive structural variations (SVs), presence/absence variations (

Natural Variations in the Activity of Hydroxycinnamoyl Transferases Promote Accumulation of Metabolites Conferring Rice Resistance

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3803-3820, June 2026.
ABSTRACT Plant‐derived secondary metabolites act as regulators of in planta defence. Plant phenylpropanoid metabolic compounds, including final metabolites such as lignin and flavonoids, and a few intermediate metabolites play critical roles in defence.

Multi-trait association study identifies loci associated with tolerance of low phosphorus in Oryza sativa and its wild relatives

Scientific Reports, 2022
We studied variation in adaptive traits and genetic association to understand the low P responses, including the symbiotic association of arbuscular mycorrhizal (AM) fungal colonization in Oryza species (O. sativa, O. nivara, and O. rufipogon).

Molecular Control of Tiller Angle and Its Role in Rice Domestication

Food and Energy Security, Volume 15, Issue 3, May/June 2026.
ABSTRACT Plant architecture is a key determinant of rice (Oryza sativa) productivity, with tiller angle playing a central role in optimizing plant density, light interception, and yield. During domestication, rice underwent a critical transition from the prostrate growth habit of wild relatives such as Oryza rufipogon to the erect architecture of ...

Phylogenetic analysis of Oryza rufipogon strains and their relations to Oryza sativa strains by insertion polymorphism of rice SINEs

Genes & Genetic Systems, 2007
Oryza rufipogon, the progenitor of the cultivated rice species Oryza sativa, is known by its wide intraspecific variation. In this study, we performed phylogenetic analyses of O. rufipogon strains and their relationships to O. sativa strains by using 26 newly identified p-SINE1 members from O.

Taxonomic insights into Indian Rotala (Lythraceae) species with verticillate phyllotaxy

Nordic Journal of Botany, Volume 2026, Issue 5, May 2026.
In an effort to resolve taxonomic complexities among Indian Rotala species with verticillate phyllotaxy, this study provides an identification key, revised nomenclature, updated morphological descriptions including SEM studies of seed coat surfaces, detailed photoplates, and notes on phenology, ecology, and distribution.

Identification and characterization of Australian wild rice strains of Oryza meridionalis and Oryza rufipogon by SINE insertion polymorphism

Genes & Genetic Systems, 2005
Of the rice species with an AA genome, Oryza meridionalis has been identified in northern Australia as a species of the annual type, among those previously classified as Oryza perennis, Oryza rufipogon or Oryza nivara. This notion has, however, led to some confusion to determine which strains belong to O.

Integrated RNA Sequencing and QTL Mapping to Identify Candidate Genes from Oryza rufipogon Associated with Salt Tolerance at the Seedling Stage

Frontiers in Plant Science, 2017
Soil salinity is a common abiotic stress affecting crop productivity. To identify favorable alleles from wild rice (Oryza rufipogon Griff.) that enhance salinity tolerance of rice (O. sativa L.), a set of introgression lines (ILs) were developed. The ILs
