Something old, something new: Evolution of Colombian weedy rice (Oryza spp.) through de novo de-domestication, exotic gene flow, and hybridization. [PDF]

open access: yesEvol Appl, 2020
Abstract Weedy rice (Oryza spp.) is a worldwide weed of domesticated rice (O. sativa), considered particularly problematic due to its strong competition with the crop, which leads to reduction in yields and harvest quality. Several studies have established multiple independent origins for weedy rice populations in the United States and various parts of

Resistance and susceptibility QTL identified in a rice MAGIC population by screening with a minor-effect virulence factor from Xanthomonas oryzae pv. oryzae. [PDF]

open access: yesPlant Biotechnol J, 2021
Summary Effective and durable disease resistance for bacterial blight (BB) of rice is a continuous challenge due to the evolution and adaptation of the pathogen, Xanthomonas oryzae pv. oryzae (Xoo), on cultivated rice varieties. Fundamental to this pathogens’ virulence is transcription activator‐like (TAL) effectors that activate transcription of host ...

Allelic variation for broad-spectrum resistance and susceptibility to bacterial pathogens identified in a rice MAGIC population. [PDF]

open access: yesPlant Biotechnol J, 2018
Summary Quantitative trait loci (QTL) that confer broad‐spectrum resistance (BSR), or resistance that is effective against multiple and diverse plant pathogens, have been elusive targets of crop breeding programmes. Multiparent advanced generation intercross (MAGIC) populations, with their diverse genetic composition and high levels of recombination ...

Development and field performance of nitrogen use efficient rice lines for Africa. [PDF]

open access: yesPlant Biotechnol J, 2017
Summary Nitrogen (N) fertilizers are a major input cost in rice production, and its excess application leads to major environmental pollution. Development of rice varieties with improved nitrogen use efficiency (NUE) is essential for sustainable agriculture.

Trends in rice research: 2030 and beyond

open access: yesFood and Energy Security, Volume 12, Issue 2, March 2023., 2023
We have analysed the trends in rice research in the past three decades in both Asian (Oryza sativa) and African (O. glaberrima) rice, with their impact on rice cultivation. We have also analysed the trends in population growth, rice cultivation, production, price, consumption and varietal release along with their projections for 2030 and beyond ...

Thermal and physicochemical properties of starches from three Colombian rice varieties

open access: yesAgronomía Colombiana, 2017
Samples of starch from broken grains of three rice varieties grown in Colombia were analyzed to determine their physicochemical and thermal properties: Fedearroz 473 (F473), Fedearroz 50 (F50) and Fedearroz 60 (F60).
