<P>Although genetic diversity has a cardinal role in domestication, abundant natural allelic variations across the rice genome that cause agronomically important differences between diverse varieties have not been fully explored. Here we implement an approach integrating genome-wide association testing with functional analysis on grain size in a diverse rice population. We report that a major quantitative trait locus, GLW7, encoding the plant-specific transcription factor OsSPL13, positively regulates cell size in the grain hull, resulting in enhanced rice grain length and yield. We determine that a tandem-repeat sequence in the 5'UTR of OsSPL13 alters its expression by affecting transcription and translation and that high expression of OsSPL13 is associated with large grains in tropical japonica rice. Further analysis indicates that the large-grain allele of GLW7 in tropical japonica rice was introgressed from indica varieties under artificial selection. Our study demonstrates that new genes can be effectively identified on the basis of genome-wide association data.</P>

Nosema ceranae, a newly emergent parasite invading western honey bees (Apis mellifera L.), is indicated to threaten honey bee health at both individual and colony levels. However, the efficient and environmentallyfriendly treatments are quite limited at present. To find alternative medicine to control Nosema diseases, the effect of 8 types of herbal extracts against N. ceranae infection were screened under laboratory condition. Of which, 1% Andrographis paniculata (A. paniculata) decoction was found to significantly decrease N. ceranae spore numbers on 7 days post infection (dpi) and 13 dpi. Then, our results further revealed that A. paniculata decoction at doses ranging from 1% to 7% displayed significant efficient inhibition of Nosema spore proliferation and improved the infected bees’ survival rates in a dose-dependent manner. A. paniculata decoction was found to protect the gut tissues of infected workers from damage cause by N. ceranae, which might be due to the regu lation of the expression of certain genes in Wnt and JNK pathways, including armadillo, basket, frizzled2 and groucho. Additionally, our study suggested that A. paniculata decoction performed this Nosema spore-reducing potential over its two monomers, andrographolide and dehydrographolide. Taken together, this work enables us to better understand A. paniculata decoction’s potential to inhibit N. ceranae infection, thus providing a new guidance for developing applicable drugs to control Nosema diseases.

PURPOSE In this study, The event-destination image transfer model was used to predict and test the behavioral intention of spectators watching major sports events. Based on The Event-destination image transfer model, this study added place attachment as a new variable to investigate The influencing factors of audience decision-making process. METHOD This study sampled 500 spectators of the 2019 FIBA Basketball World Cup held in Beijing, China. The 2019 FIBA Basketball World Cup was held in Beijing, Guangzhou, Nanjing, Shanghai, Wuhan, Shenzhen, Foshan and Dongguan on September 15, 2019. RESULT After spectators attend a mega-event held in a tourism destination, the event image positively affected the destination image. Destination image directly and positively affected spectators' behavioral intentions toward the destination. Tourists' overall attitude toward the destination was influenced positively by both the destination image and event image. CONCLUSION There are three significant antecedents factors for the behavioral intention of the destination, namely the image of the destination, tourists' overall attitude towards the destination and place attachment. The destination image directly and positively affects place attachment. Place attachment directly and positively affects tourists' behavioral intentions toward the destination.
