An IRAT109 NAM population: Genetic characterization and mapping utility for trait dissection in japonica rice (Oryza sativa L.). [PDF]

Plant Genome
Abstract Complex agronomic traits in rice (Oryza sativa L.) are controlled by many genetic loci; however, dissection is often constrained in biparental mapping populations by limited recombination and narrow genetic diversity, and in diversity sets by spurious associations arising from cryptic relatedness.

Study of Rhizosphere Microbial Community Structures of Asian Wild and Cultivated Rice Showed That Cultivated Rice Had Decreased and Enriched Some Functional Microorganisms in the Process of Domestication

Diversity, 2022
Asian cultivated rice (Oryza sativa L.), domesticated from Asian wild rice, is a staple food crop for populations around the world. Asian cultivated rice has undergone physiological changes in the process of its evolution from Asian wild rice, and the ...

Combined application of salicylic acid and silicon enhances photosynthetic capacity and yield in different dry-cultivated rice varieties: associations with osmotic adjustment substances and antioxidant enzyme activity

Frontiers in Plant Science
Single applications of silicon (Si) and salicylic acid (SA) can alleviate plant stress. However, the effects of their combined application on dry-cultivated rice and the differences between varieties remain unclear.

Uptake and utilization of different nitrogen forms in erect panicle japonica rice cultivar

Journal of Plant Interactions, 2019
The response of rice to nitrogen (N) was compared between three rice cultivars and three N treatments: 1:0, 0:1, and 1:1 NH4+:NO3−. The three rice cultivars used were: Shennong1401 (SN1401, erect panicle rice cultivar) and Habataki and Sasanishiki ...
