Genetic Mapping Reveals a Candidate Gene (ClFS1) for Fruit Shape in Watermelon

The polyploidy watermelon breeding group of Zhengzhou Fruit Research Institute of Chinese Academy of Agricultural Sciences (CAAS) reveals a candidate gene for fruit shape in watermelon. The related paper was recently published on Theoretical and Applied Genetics.
As an important cucurbit crop throughout the world, watermelon presents different fruit shapes including elongate, oval and spherical. However, the genetic pattern and the developmental mechanisms of watermelon fruit shape are not justified yet.
In this study, Segregation analysis suggested that fruit shape of watermelon was controlled by a single locus and elongate fruit (OO) was incompletely dominant to spherical fruit (oo) with the heterozygote (Oo) being oval fruit. According to BSA-seq and GWAS, we demonstrated that Cla011257 gene was the candidate gene of watermelon fruit shape (ClFS1), The CDS of Cla011257 had a 159 bp deletion which resulted in the omission of 53 amino acids in elongate watermelon.

OsPK2 Encodes a Plastidic Pyruvate Kinase Involved in Rice Endosperm Starch Synthesis, Compound Granule Formation and Grain Filling

Recently, a research team led by Professor Hu Peisong from China Rice Research Institute of Chinese Academy of Agricultural Sciences (CAAS) has made a great progress on new regulatory mechanism of rice starch synthesis and grain development.
Starch is the essential carbohydrate storage material in plants. The genetic basis of starch synthesis and grain development was a complex regulatory network. Although several enzymes and regulators of starch biosynthesis have been defined, the complete molecular mechanism remains largely unknown. Therefore, identification and characterization of different rice endosperm defective mutants are necessary for further understanding this process in rice.Read more >>

Genomic Variation in 3,010 Diverse Accessions of Asian Cultivated Rice

Asian cultivated rice (Oryza sativa L.) is grown worldwide as staple food of half of the world. By the year 2035, an additional 112 million metric tons of rice must be produced with less land and water under more fluctuating climates, requiring future rice cultivars with higher yielding and resilient to multiple abiotic and biotic stresses. The foundation to continuous improvement of rice is the rich genetic diversity within its population and wild relatives.
Recently, a research team led by Dr. Zhikang Li from Institute of Crop Sciences of Chinese Academy of Agricultural Sciences (CAAS), has analyzed genetic variation, population structure and diversity among 3,010 diverse Asian cultivated rice (Oryza sativa L.) genomes from the 3,000 Rice Genomes Project, which was participated by 16 universities and institutes from China and abroad as well.

CAAS Revealed the Role of RXFP2 in the Development of a Unique Horn Phenotype in Sheep as Response to Semi-feralization by Whole-genome Sequences

Recently, the mutton sheep and goat genetics and breeding team have reported their new progress on adaptive evolutions of domestic sheep. The present study revealed that horn-related gene RXFP2 showed signs of rapid evolution in the semi-feral sheep breeds specifically. The result of this study was published in GigaScience on March 7th, 2018.
Sheep is thought to be one of the first domesticated livestock species. Animal domestication has been widely investigated in order to better understand the phenotypic and genetic changes of animals caused by human activities. However the process where domestic animals become feral is still poorly understood. Read more >>

Chinese Scientists Spot Selfish Genetic Element in Plants

After found in mice and nematodes, selfish genetic element is once again discovered in rice by Chinese scientists. This is the first time that selfish genetic element is found in plants, challenging the renowned Mendel’s Law of segregation. The article introducing such new findings has been published by the world’s top academic journals Science on June 8th, 2018. Dr. Yu Xiaowen and Prof. Zhao Zhigang from the College of Agriculture of Nanjing Agricultural University are the first authors of this article, and Dr. Wan Jianmin, an academician of Chinese Academy of Agricultural Sciences (CAAS), also vice president of CAAS, is the corresponding author.
What about selfish genes? The core of Mendelian genetics is the concept that gametes are equally likely to carry either of the two parental copies of a gene. In fact, offspring traits might be more similar to those of its father or mother. The same also goes to the selfish genetic element in rice. Read more >>
