Adapted conservation agriculture practices can increase energy productivity and lower yield-scaled greenhouse gas emissions in coastal Bangladesh by Krupnik, Timothy J., Hossain, Mohammed Khaled, Timsina, Jagadish, Gathala, Mahesh Kumar, Sapkota, Tek Bahadur, Yasmin, Samina, Shahjahan, Md., Hossain, Farhad, Kurishi, Alanuzzaman, Miah, Azahar Al, Saidur Rahman, B.M., McDonald, Andrew J.

“…We hypothesized that rotating rice (Oryza sativa) with maize (Zea mays) using conservation agriculture, or CA (i.e., strip-tilled maize followed by unpuddled transplanted rice), or seasonally alternating tillage (SAT, i.e., strip-tilled maize followed by fully-tilled, puddled rice with residues retained across rotations) would reduce costs and energy use, increase energy-use efficiency, and reduce yield-scaled CO2-eq emissions (YSE) and total global warming potential (GWP), compared to farmers’ own practices (FP) and conventional full-tillage (CT) under the same rotation in Bangladesh’s coastal region. …”

Validation of a high-confidence regulatory network for gene-to-NUE phenotype in field-grown rice by Shanks, Carly M., Huang, Ji, Cheng, Chia-Yi, Shih, Hung-Jui S., Brooks, Matthew D., Álvarez, José M., Araus, Viviana, Swift, Joseph, Henry, Amelia, Coruzzi, Gloria M.

“…To address this issue, we aim to uncover the gene regulatory networks (GRNs) that regulate nitrogen use efficiency (NUE) - as a function of water availability - in Oryza sativa, a staple for 3.5 billion people. In this study, we infer and validate GRNs that correlate with rice NUE phenotypes affected by N-by-W availability in the field. …”

Descriptors for wild and cultivated rice (Oryza spp.) by Bioversity International, International Rice Research Institute, Africa Rice Center

“…Descriptors for wild and cultivated rice (Oryza spp.)' is a revision of the original IBPGR and IRRI publication 'Descriptors for rice (Oryza sativa L.)' (1980), expanded to include descriptors for wild rice species of the genus Oryza, and harmonized as far as possible with descriptors developed by the International Union for the Protection of New Varieties of Plants (UPOV 2004; www.upov.org) for new cultivars of cultivated rice. …”

Phenotyping and QTL mapping for cold tolerance at the germination and seedling stages in Argentine temperate rice by Bonell, Martha Lucrecia, Arguissain, Gustavo Gabriel, Crepy, Maria Andrea, Fernandez, Paula Del Carmen, Heinz, Ruth Amelia

“…In Argentina, the yield potential of rice (Oryza sativa L.) under suboptimal temperatures of temperate regions and during early sowing in tropical regions depends on its low-temperature germinability (LTG) and subsequent cold tolerance at the seedling stage (CTS). …”

Efecto del envejecimiento del arroz cáscara en la calidad del grano by Pascual-Villalobos, María J., Losana, L., Ruiz-Egea, J., Carreres, Ramón

“…La mayoría de las variedades de arroz (Oryza sativa) cultivadas en España son variedades con un contenido en amilosa bajo (12,1-20%) a excepción de las variedades Bomba y Albufera que tienen un contenido intermedio-alto, dando lugar a arroces cuyos granos cocidos tienden a quedar mássueltos y presentar mayor resistencia a la masticación (Carreres y Bretó, 2006). …”
