Mar 4, 2021 · By screening allotetraploid wild rice inventory, we identified one genotype of Oryza alta (CCDD), polyploid rice 1 (PPR1), and established two important resources for its de novo domestication: (1) an efficient tissue culture, transformation, and genome editing system and (2) a high-quality genome assembly discriminated into two subgenomes of ...

Jan 9, 2024 · Li, a plant geneticist at the Institute of Genetics and Developmental Biology in Beijing, is working on a wild rice species from South America called Oryza alta. It produces edible, nutritious...

Apr 7, 2024 · Oryza alta Swallen (O. alta) is an important allo-tetraploid (2n = 48, CCDD) wild rice. O. alta, a rare but precious germplasm material for breeding purposes, has many excellent characteristics that have been lost in cultivated rice (Solis et al., 2021; Yu et al., 2021).

Oct 28, 2022 · We present a protocol for <i>Agrobacterium</i>-mediated genetic transformation and genome editing in wild allotetraploid rice <i>Oryza alta</i>. We detail steps to induce embryogenic calli from mature seeds and co-cultivate with <i>Agrobacterium</i> after infection.

Feb 16, 2018 · Oryza alta Swallen is a species of allotetraploid wild rice (CCDD, 2n = 48) that possesses a high biomass production and is resistant to several insects and diseases. Resistance to striped stem borer and bacterial grain rot disease was also reported in …

Mar 4, 2021 · In this issue of Cell, Yu et al., 2021 report a route of de novo domestication of an allotetraploid rice, Oryza alta. It represents the first de novo domestication of not only a wild cereal but also a polyploid plant.

Dec 16, 2022 · We present a protocol for Agrobacterium -mediated genetic transformation and genome editing in wild allotetraploid rice Oryza alta. We detail steps to induce embryogenic calli from mature seeds and co-cultivate with Agrobacterium after infection.

Apr 8, 2024 · The pan-genome sequences of wild rice species with CCDD genome were constructed by integrating 8 Oryza alta (OA), 2 Oryza grandiglumis (OG) and 18 Oryza latifolia (OL) accessions.

Modern cultivated rice (Oryza sativa) as one of the most important staple cereals are all diploid, and polyploidization of rice is long-desired for superior advantages in increasing yield, genome buffering, heterosis and adaptive potential to rapid environmental changes.

Sep 1, 2010 · In order to reveal the origin and evolutionary relationship between two CCDD genome species, Oryza alta and Oryza latifolia, fluorescence in situ hybridization (FISH) was adopted to analyze the genomes of the two species with C0t-1 DNA from O. alta as a probe.
