Towards a perennial upland and rice

, 1998
In order to provide both a means of livelihood and control erosion in the uplands of Southeast Asia, a perennial upland rice is under development. Genes for rhizome expression are being introgressed from Oryza longistaminata (Ol) into O. sativa (Os).

Genotype by environment interactions for performance of perennial rice genotypes (Oryza sativa L./Oryza longistaminata) relative to annual rice genotypes over regrowth cycles and locations in southern China

Field Crops Research, 2019
Genotype by environment (GxE) interactions for performance of 5 perennial rice genotypes (Oryza sativa L./Oryza longistaminata) were examined relative to 1 mutant and 3 annual rice genotypes over 2–6 growth cycles at 7 locations in southern China between

Transient and stable expression ofgusA fusions with rice genes in rice, barley and perennial ryegrass

Plant Molecular Biology, 1993
Transcriptional and translational fusions were made between the reading frame coding for beta-D-glucuronidase and sequences of either a constitutively expressed rice gene (GOS2) involved in initiation of translation or a light-inducible rice gene (GOS5). The transient expression of the fusions was studied via particle bombardment of seedling tissues of

Locating QTLs controlling overwintering trait in Chinese perennial Dongxiang wild rice

Molecular Genetics and Genomics, 2017
Overwintering (OW) is the process by which rice passes through the winter season and germinates in the following spring. OW is also a typical quantitative inheritance trait. Currently, the molecular genetic basis of OW trait in Chinese perennial Dongxiang wild rice (DXWR) still remains to be known.

Switch to perennial rice promotes sustainable farming

2023
The successful breeding and cultivation of perennial rice enables up to eight grain harvests from a single planting, with reduced labour input, improved soil health and potential to affect farming systems in frost-free environments between 40 degrees N and 40 degrees S. Perennial rice reconciles food production with environmental security in a changing

Phylogenetic relationships of annual and perennial wild rice: probing by direct DNA sequencing

Theoretical and Applied Genetics, 1991
The phylogenetic relationships between Asian wild rice strains were analyzed by direct sequencing of PCR-amplified DNA fragments. The sequence of three introns located in the phytochrome gene was determined for eight strains of the Asian wild rice, Oryza rufipogon, and one strain of the related African species, Oryza longistaminata.

Resetting of a tandem microRNA156 enables vegetative perennial growth in rice

Science
Annual cultivated rice was domesticated from perennial wild rice, yet the genetic mechanism of perennial growth habit remains unclear. Using introgression lines of wild and cultivated rice, we identified the Endless Branches and Tillers ( EBT1 ) locus ...

Variation in Resource Allocation and Adaptive Strategy of a Wild Rice, Oryza perennis Moench

Botanical Gazette, 1982
Patterns of resource allocation were investigated to analyze variations in adaptive mechanisms in 54 strains of the complex Oryza perennis, which exhibited a perennial-annual continuum. The proportion of seed weight to total dry weight, an indication of reproductive effort, ranged from near 0% in some perennials to 50% in some Asian wild annual strains
