Genomic signatures of domestication and adaptation during geographical expansions of rice cultivation por Zheng, Xiaoming, Pang, Hongbo, Wang, Junrui, Yao, Xuefeng, Song, Yue, Li, Fei, Lou, Danjing, Ge, Jinyue, Zhao, Zongyao, Qiao, Weihua, Kim, Sung-Ryul, Ye, Guoyou, Olsen, Kenneth M., Liu, ChunMing, Yang, Qingwen

“…Rice (Oryza sativa L.), a global staple food now grown on all inhabited continents, was domesticated from its wild progenitor, O. rufipogon Griff., in tropical and subtropical regions of Asia (Oka, 1988). After domestication, the expansions of rice landraces into the present-day range required a diverse array of adaptations to local environments, which included changes in daylight sensitivity, expanded thermal tolerance (for excess cold and heat), adaptations to water availability (drought and waterlogging), and resistance to biotic stresses (Garris et al., 2005; Glaszmann, 1987). …”

Temperature-dependent oviposition and nymph performance reveal distinct thermal niches of coexisting planthoppers with similar thresholds for development por Horgan, Finbarr G., Arida, Arriza, Ardestani, Goli, Almazan, Maria Liberty P.

“…The brown planthopper (Nilapavata lugens: BPH) and whitebacked planthopper (Sogatella furcifera: WBPH) co-occur as the principal pests of rice in Asia. A review of previous studies suggests that the two species have similar temperature tolerances and similar temperature thresholds for development. …”

Multivariate-based classification of predicting cooking quality ideotypes in rice (Oryza sativa L.) indica germplasm por Cuevas, Rosa Paula O., Domingo, Cyril John, Sreenivasulu, Nese

“…For predicting texture suited for South and South East Asia, most of the breeding programs tend to focus on developing rice varieties with intermediate to high amylose content in indica subspecies. …”

What is the value of sustainably-produced rice? Consumer evidence from experimental auctions in Vietnam por My, Nguyen H.D., Demont, Matty, Van Loo, Ellen J., de Guia, Annalyn, Rutsaert, Pieter, Tuan, Tran Huu, Verbeke, Wim

“…Little is known about the value of sustainably-produced rice and incentive mechanisms for the adoption of sustainable production standards throughout rice value chains in Southeast Asia. This study tests the feasibility of a market-based incentive mechanism by eliciting consumers’ willingness-to-pay (WTP) for rice produced and labeled under a national sustainable production standard in the South of Vietnam through experimental auctions. …”

Sequencing of Australian wild rice genomes reveals ancestral relationships with domesticated rice por Brozynska, Marta, Copetti, Dario, Furtado, Agnelo, Wing, Rod A., Crayn, Darren, Fox, Glen, Ishikawa, Ryuji, Henry, Robert J.

“…A test for admixture showed possible introgression into the Australian Taxon A (diverged around 1.6 million years ago) especially from the wild indica/O. nivara clade in Asia. These results demonstrate that northern Australia may be the centre of diversity of the A genome Oryza and suggest the possibility that this might also be the centre of origin of this group and represent an important resource for rice improvement.…”

More food, but less land and water for nature: why agricultural productivity gains did not materialize por Seijger, C., Urfels, A., Christoforidou, M., Hellegers, P., Borghuis, G., Langan, Simon, van Halsema, G.

“…Instead of consolidating cereal production and trade in favourable regions like North America, Europe and Russia, their arable land declined by 35 million hectares, while arable land expanded by 74 million hectares in Africa, Latin America and Eastern Asia. Likewise, water productivity gains did not materialize, as photosynthesis breakthroughs did not occur. …”

Genetic dissection of grain zinc concentration in spring wheat for mainstreaming biofortification in CIMMYT wheat breeding por Velu, Covindan, Singh, Ravi Prakash, Crespo-Herrera, Leonardo, Juliana, Philomin, Dreisigacker, Susanne

“…Approximately two billion people suffer from micronutrient deficiency, thus breeders have crossed high Zn progenitors such as synthetic hexaploid wheat, T. dicoccum, T. spelta, and landraces to generate wheat varieties with competitive yield and enhanced grain Zn that are being adopted by farmers in South Asia. Here we report a genome-wide association study (GWAS) using the wheat Illumina iSelect 90 K Infinitum SNP array to characterize grain Zn concentrations in 330 bread wheat lines. …”
