Recently, a paper named “PaCYP78A9, a Cytochrome P450, Regulates Fruit Size in Sweet Cherry (Prunusavium L.)”reported by sweet cherry germplasm improvement research team from Zhengzhou Fruit Research Institute of Chinese Academy of Agricultural Sciences (CAAS) was published on the Frontiers in Plant Sciences. The essential role of PaCYP78A9 controlling the fruit size in P. avium was investigated in this paper. Sweet cherry (Prunusavium L.) is an important fruit crop in which fruit size is strongly associated with commercial value; few genes associated with fruit size have, however, been identified in sweet cherry. Here, we characterized a P. avium CYP78A gene PaCYP78A9 that is thought to be...

The research team led by Professor Gu Qinsheng from the Zhengzhou Fruit Research Institute of Chinese Academy of Agricultural Sciences (CAAS) has been working on the prevention and control of cucurbit viral diseases. As cross-protection comes up, it supplies an interesting and efficient mean for the control of cucurbit viruses. Herein, an important research stride on the construction of infectious clones of cucurbit viruses and the acquisition of good candidates to attain stable symptom attenuation for them has been made. Herein, an agroinfectious cDNA clone for the hn isolate of Cucumber green mottle mosaic virus (CGMMV) was developed and a nonconserved mutation involving a single nucleoti...

The polyploidy watermelon breeding group of Zhengzhou Fruit Research Institute, 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 word, 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 th...

In August, the Journal of 'frontiers in plant sciences' published a paper entitled"Transcriptomic Analysis Reveals Candidate Genes for Female Sterilityin Pomegranate Flowers" reported by Cao Shangyin's lab from Zhengzhou Fruit Research Institute, CAAS. In this paper, the authors reported the key stage and reason for female sterility as well as the candidate genes controlling and regulating female sterility in pomegranate. Pomegranate (Punica granatum L.) is a shrub that is native to central Asia (Holland et al., 2009), it is valued for its juicy aril sacs,which are claimed to be of benefit to human health. Two types of flowers are produced on anindividual pomegranate tree: FMF and BF). FMFs...

An important research progress which described cell wall polysaccharide nanostructures and quality of postharvest apricot during cold storage was achieved by the Department of Fruit Processing and Storage at the Zhengzhou Fruit Research Institute and published in Food Chemistry in January, 2017. The paper investigated the nanostructure and characterization of cell wall polysaccharides, analyzed the quantitative results and induced the degradation pathway of pectin chains during the fruit softening. The detailed mechanism may be of interest for future fruit texture properties and postharvest storage research. The texture of fruit is a key quality parameter that affects consumer preference. T...

A new research result named Experimental and molecular docking investigations on the inclusion mechanism of the complex of phloridzin and hydroxypropyl-β-cyclodextrin was achieved by one team headed by Jiao Zhonggao at the Zhengzhou Fruit Research Institute and published in Food Chemistry in July, 2016. This study could prompt the application of phloridzin in food industry and guide the molecular design of hydroxypropyl-β-cyclodextrin (HP-β-CD). Phloridzin is a dihydrochalcone primarily found in apples and Lithocarpus polystachyus Rehd(a traditional Chinese sweet tea) with many health-promoting functions, such as antioxidant, antidiabetic, antitumor and anti-inflammatory activites. Due to i...

An important researchprogress which described genome-wide association study of 12 agronomic traits in peach was achieved by one team headed by Wang Lirong at the Zhengzhou Fruit Research Institute and published in Nature Communications in November, 2016. The paper was recommended to be put into the ‘Highlight’ column because of its significance. And the editor said that: Lirong Wang and Zhixi Tian and colleagues report genetic regions that are associated with twelve important traits relevant to the taste and appearance of the fruit, providing valuable genetic data that could be used to inform future breeding efforts. Such insights are not only important from a practical agronomic perspective...

Recently, two new nectarine varieties,‘CN13’ and ‘CN15’, has grantedplant variety protection from ministry of agriculture, those varietiesbeing developed by the peach breeding team led by Professor Wang Zhiqiang from Zhengzhou Fruit Research Institute of CAAS. ‘CN13’ is a white flesh table-nectarine variety, the average ripeningdate in Zhengzhouislate June, fruit shape is round and groundcolor of fruit skin is cream white with bright red blush, average fruit weight for ‘CN13’was 201 g and the big fruit weightgreater than 300 g. Fruits of ‘CN13’are clingstone, melting flesh, have a very sweet flavor and lot of anthocyanins in flesh.The average soluble solids, total sugar, total acidity andVc...

Recently, two flat peach varieties ‘Zhongpantao10’and ‘Zhongpantao 11’ have beenreleased by Lirong Wang’s peach genetics and breeding team of Zhengzhou Fruit Research Institute, Chinese Academy of Agricultural Sciences (ZFRI-CAAS) and authorized by the Office of the Protection of New Varieties of Plants. Zhongpantao 10 Zhongpantao11 Flat peach (Prunuspersica)is the Chinese traditional favorite fruit. However, some defaults such as splitting stone, thin skin, soft flesh and short shelf life are present in production, whichlimits the flat peach development in...

Recently, researchers at the Zhengzhou Fruit Research Institute (ZFRI) of Chinese Academy of Agricultural Sciences (CAAS) have made a periodical progress on the research of peach resequencing. Through a large-scale resequencing of 10 wild and 74 cultivated peach varieties, a phylogenetic tree based on the genetic distances calculated from the genotypes at all the SNP positions of the 84 peach varieties were constructed. Meanwhile, 147 and 262 genes under edible and ornamental selection were identified, respectively. The research has been published online in the GenomeBiologyon July 31th, 2014. According to Dr. Wang Lirong, head of the research team at the ZFRI, the cultivated population has...
