SPR9 encodes a 60 S ribosomal protein that modulates panicle spreading and affects resistance to false smut in rice (Oryza sativa. L).

Background: The architecture of inflorescence in crops is a key agronomic feature determining grain yield and thus has been a major target trait of cereal domestication.

Results: In this study, we show that a simple spreading panicle change in rice panicle shape, controlled by the Spreading Panicle 9 (SPR9) locus, also has a significant impact on the resistance to rice false smut (RFS). Meanwhile, we mapped a novel spr9 mutant gene between markers Indel5-18 and Indel5-22 encompassing a genomic region of 43-kb with six candidate genes.

The Genetic Mechanism of the Immune Response to the Rice False Smut (RFS) Fungus .

Rice false smut (RFS), which is caused by (), has become one of the most devastating diseases in rice-growing regions worldwide. The disease results in a significant yield loss and poses health threats to humans and animals due to producing mycotoxins. In this review, we update the understanding of the symptoms and resistance genes of RFS, as well as the genomics and effectors in .

Fine Mapping and Cloning of a Affect the Ratooning Ability in Rice ( L.).

Ratooning ability is a key factor that influences the ratoon rice yield in areas where light and temperature are not sufficient for second-season rice. Near-isogenic lines (NILs) are the most powerful tools for the detection and precise mapping of quantitative trait loci (QTLs). In this study, using 176 NILs, we identified a novel QTL for ratooning ability in NIL128.

Analysis of a rice blast resistance gene Pita-Fuhui2663 and development of selection marker.

Rice blast is a detrimental rice disease caused by the fungus Magnaporthe oryzae. Here, we identified a resistance gene from the rice cultivar Fuhui 2663 which is resistant to the rice blast isolate KJ201. Through isolated population analyses and sequencing approaches, the candidate gene was traced to chromosome 12.

Fine Mapping and Cloning of a Major QTL , Which Simultaneously Affects the Plant Height, Panicle Length, Spikelet Number and Yield in Rice ( L.).

Plant height is one of the most important agronomical traits in rice ( L.). Introducing the rice in the 1960s significantly enhanced the rice yield potential in Asia.

Cloning of long sterile lemma (lsl2), a single recessive gene that regulates spike germination in rice (Oryza sativa L.).

Background: Rice is a typical monocotyledonous plant and an important cereal crop. The structural units of rice flowers are spikelets and florets, and floral organ development and spike germination affect rice reproduction and yield.

Results: In this study, we identified a novel long sterile lemma (lsl2) mutant from an EMS population.

WSL5, a pentatricopeptide repeat protein, is essential for chloroplast biogenesis in rice under cold stress.

Chloroplasts play an essential role in plant growth and development, and cold conditions affect chloroplast development. Although many genes or regulators involved in chloroplast biogenesis and development have been isolated and characterized, many other components affecting chloroplast biogenesis under cold conditions have not been characterized. Here, we report the functional characterization of a white stripe leaf 5 (wsl5) mutant in rice.

Genetic dissection of seed storability using two different populations with a same parent rice cultivar N22.

Seed storability in rice (Oryza sativa L.) is an important agronomic trait. Two segregating populations with N22 (indica) as a common parent, viz.
