Xianning City of Hubei Province is one of the five major traditional osmanthus producing areas in the world and the hometown of osmanthus in China. Xianning is constructing China osmanthus City in the whole city. This paper first introduces the main characteristics of the osmanthus industry in Xianning City, and analyzes the characteristics of traditional knowledge, biological genetic resources, new plant varieties, patents, geographical indications, and trademarks. Then, it studies the intellectual property resources of the osmanthus industry, and analyzes the main problems existing in the construction of China osmanthus City and intellectual property right protection. Finally, it comes up with constructive recommendations including applying for China and Globally Important Agricultural Heritage Systems, developing colored-leaf osmanthus varieties, creating a regional public brand of osmanthus specialty products, and building a new development pattern of osmanthus industry.

The phylogenetic relationships of osmanthus Lour.were investigated using the nuclear ribosomal internal transcribed spacer(ITS) regions and non-coding chloroplast regions(psbA-trnH,trnL-F).The two datasets support the conclusion that osmanthus is polyphyletic,with some species of the subtribe Oleinae nested within osmanthus.osmanthus didymopetalus P.S.Green is nested within the clade formed by species of section osmanthus in two trees.osmanthus attenuatus P.S.Green,O.yunnanensis P.S.Green,and O.gracilinervis R.L.Lu of traditional section osmanthus are clearly divergent from other accessions,and do not form a monophyletic group with other osmanthus accessions.osmanthus marginatus Hemsl.is embedded in the clade formed by species of section osmanthus in the ITS tree.In cpDNA trees all species of section osmanthus are placed in the large clade and all species of section Leiolea formed a group.The taxonomic incongruence among trees for ITS and cpDNA indicate hybridization,as introgression may have occurred among some species of sections osmanthus and Leiolea.Phylogeny of osmanthus is discussed in light of molecular and morphological data,and a revised infrageneric classification with three sections(Leiolea,Siphosmanthu,and osmanthus) is presented.The section Linocieroides is abandoned and united with section osmanthus.

In the flavonoid biosynthesis pathway, Chalcone synthase (CHS) is involved in the formation of the pigment and has been shown to be a rate-limiting enzyme for the synthesis of flavonoids. In this study, a PCR approach was used to clone a Chalcone synthases cDNA from flower of sweet osmanthus “Chenghong Dangui” and it was designated as OfCHS (O. fragrans, CHS). The cDNA was 1383 bp long and a coding sequence (CDS) of 1173 bp encoding a polypeptide of 391 amino acids with an estimated molecular mass of 39.9 kDa. The theoretical isoelectric point was 6.23. Phylogenetic analysis demonstrated that OfCHS clustered with Olea europaea, Solenostemon scutellarioides, Perilla frutescens, Antirrhinum majus and Digitalis lanata. We also detected the expression of OfCHS in different tissues in “Dangui” and in two cultivars with varied coloration, “Zi Yingui” and “Chenghong Dangui” at different floral stages using quantitative real-time PCR. We observed that OfCHS transcript was higher in leaves than in petals in “Dangui”. The transcripts of OfCHS in “Zi Yingui” petals were higher than those in “Dangui” at three stages especially at xianyan stage and there was no significant difference between the two cultivars in the full flowering stage. “Chenghong Dangui” has a relatively high anthocyanin content compared to “Zi Yingui”. The relative amount of anthocyanin of “Chenghong Dangui” initially increases, and then decreases during the bloom period. However, the expression of CHS is the highest at the initial flowering stage. These data suggest that the OfCHS does not play a key role in the accumulation of total flavonoid in this cultivar. These data could contribute to explain the different accumulation of flavonoids in petals of the two cultivars.

又到一年桂花飘香时节,国际木犀属栽培植物登录中心（ICRCO）成立也正好十周年了。芳香植物在市场中的应用日益广泛,尤其近几年形成了追捧的热潮,普遍受到民众的喜爱和欢迎,芳香植物的综合价值获得了极大的关注。芳香植物研究及应用领域,近十年取得了长足的进步。以木犀属的研究为例,我们基本弄清了桂花的品种资源、花芽分化及花期调控机理;建立了品种指纹图谱和古桂资源数据库.
