Genome-wide association study to identify chromosomal regions related to panicle architecture in rice (Oryza sativa)

Panicle architecture directly affects the grain yield of rice; meanwhile, crop domestication has increased the complexity of rice panicle size and branching pattern. Genome-wide association study (GWAS) was performed to investigate the genetic basis underlying panicle architecture using 183 rice accessions from around the world and a 7 K SNP array. Phenotyping was conducted at Texas A&M AgriLife Research Center in Beaumont, TX. GWAS was performed using MLM (Q?+?K) model using GAPIT software. At p-value?<?0.001, a total of 49 GWAS QTLs controlling various panicle architecture traits were mapped. Considering the recurring and linked SNPs across the panicle architecture traits, 42 independent QTL regions were identified. Among these, 27 QTL regions co-localized with known genes or previously reported QTLs or significant SNP markers, while 15 were potentially novel QTL regions. The results of our study offer useful information on genetic bases controlling panicle architecture in rice, which could be further validated and utilized for designing markers for use in markers assisted selection (MAS) in rice breeding programs.

Hydrolyzed casein influences intestinal mucin gene expression in the rat     

Han KS  Deglaire A  Sengupta R  Moughan PJ 《Journal of agricultural and food chemistry》2008,56(14):5572-5576

The effect of hydrolyzed casein (HC) on the expression of three mucin genes (Muc2, Muc3, and Muc4) in the rat intestine was investigated using quantitative real-time polymerase chain reaction. After a 10 day acclimatization period, rats received for 8 days the test diets containing either HC or a synthetic amino acid (SAA) mixture as the sole source of nitrogen or a protein-free (PF) diet (n = 12 per treatment). The addition of HC or the SAA mixture to the diet significantly improved average daily gain, average daily food intake, and gain:feed ratio as compared with the PF diet. Terminal ileal endogenous N flow was significantly higher for the HC-fed rats in comparison with either the SAA or the PF rats (p < or = 0.001). HC supported a significant increase of Muc3 mRNA (277 and 229% of that for diets PF and SAA, respectively; p < or = 0.05) in the small intestinal tissue and Muc4 mRNA (325 and 265% of that for diets PF and SAA, respectively; p < or = 0.05) in the colon. In conclusion, HC enhances ileal endogenous N flow and up-regulates in vivo the expression of some individual mucin genes.  相似文献
