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 ...

The high-quality O. alta genome will provide a powerful tool for molecular genetic studies of tetraploid rice, the evolution of Oryza species, and the molecular mechanisms underlying the polyploidization of higher plants.

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 8, 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).

Sep 5, 2024 · To address food security challenges and climate change, the polyploid wild rice Oryza alta has been explored as a potential crop, although it suffers from seed shattering. We employed mesoporous silica nanoparticles (MSNs) to deliver small interfering RNAs (siRNAs) for targeted gene silencing.

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 …

Oct 28, 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.

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.

structure of O. alta will surely allow the study of genomic DNA variations and pave way to DNA analysis of wild rice line using re-sequencing. Key words: Breeding, Oryza alta swallen, Population, Structure. INTRODUCTION Rice (Oryza sativa L.) is one of the most important food crops in the world. About half of the world’s population

Sep 6, 2023 · The purpose of this study is to systematically observe the segregation (population structure) of O. alta offspring and its inbred lines to provide improved base for advanced gene editing and selection using of O. alta wild rice. The study is highly significant as it is only if the rice structure is populated and studied that genomic DNA ...
