Melting the secrets of gelatinisation temperature in rice por Cuevas, Rosa P., Daygon, Venea D., Corpuz, Henry M., Nora, Leilani, Reinke, Russell F., Waters, Daniel L. E., Fitzgerald, Melissa A.

“…Gelatinisation temperature (GT) is one of the key traits measured in programs for breeding rice (Oryza sativa L.). It is commonly estimated by the alkali spreading value (ASV), and less commonly by differential scanning calorimetry (DSC). …”

Locating genes controlling allelopathic effects against barnyardgrass in upland rice por Jensen, Louise Bach, Courtois, Brigitte, Shen, Lishuang, Li, Zhikang, Olofsdotter, Maria, Mauleon, Ramil P.

“…To understand the genetic control of allelopathy in rice (Oryza sativa L.), quantitative trait loci (QTL) mapping was performed using a population of 142 recombinant inbred lines derived from a cross between cultivar IAC 165 (japonica upland variety) and cultivar CO 39 (indica irrigated variety). …”

Relationship Between Leaf Photosynthesis and Nitrogen Content of Field-Grown Rice in Tropics por Peng, Shaobing, Cassman, Kenneth G., Kropff, Martin J.

“…A field‐derived relationship between maximum single leaf net photosynthetic rate under saturating light (Amax) and leaf N content per unit leaf area (Na) is not available for rice (Oryza sativa L.). The rice simulation model ORYZA1 estimates aboveground dry matter production based on the relationship between Amax and Na determined previously under greenhouse‐growth chamber conditions. …”

Diallel Analysis of Callus Induction and Green-Plant Regeneration in Rice Anther Culture por Quimio, C.A., Zapata, F.J.

“…This study was conducted to determine the inheritance of callus induction and plant regeneration in rice (Oryza sativa L.) anther culture. Sixteen genotypes derived from a four‐parent diallel mating set of two Japonica cultivars (Taipei 309 and Taipei 177) and two indica cultivars (IR36 and Basmati 370) were evaluated for their callus induction and plant regeneration abilities. …”

New Genes for Resistance to the Green Leafhopper in Rice por Siwi, Bernard H., Khush, Gurdev S.

“…The inheritance of resistance to the green leafhopper (Nephotettix virescens Distant) was studied in 13 cultivars of rice (Oryza sativa L.). Seedlings at the one‐leaf stage were artificially infested in the greenhouse with second‐ and third‐instar nymphs of the green leafhopper. …”

Genomic analysis of NAC transcription factors in banana (Musa acuminata) and definition of NAC orthologous groups for monocots and dicots por Cenci, A., Guignon, Valentin, Roux, N., Rouard, M.

“…In order to clarify the orthologous relationships among NAC genes of different species, we performed an in-depth comparative study of four divergent taxa, in dicots and monocots, whose genomes have already been completely sequenced: Arabidopsis thaliana, Vitis vinifera, Musa acuminata and Oryza sativa. Due to independent evolution, NAC copy number is highly variable in these plant genomes. …”
