Cotton fibers elongate rapidly after initiation of elongation, eventually leading to the deposit of a large amount ofcellulose. To reveal features of cotton fiber cells at the fast elongation and the secondary cell wall synthesis stages, wecompared the respective transcriptomes and metabolite profiles. Comparative analysis of transcriptomes by cDNA arrayidentified 633 genes that were differentially regulated during fiber development. Principal component analysis (PCA)using expressed genes as variables divided fiber samples into four groups, which are diagnostic of developmental *** grouping results are also found if we use non-polar or polar metabolites as variables for PCA of developingfibers. Auxin signaling, wall-loosening and lipid metabolism are highly active during fiber elongation, whereas cellulosebiosynthesis is predominant and many other metabolic pathways are downregulated at the secondary cell wall synthesisstage. Transcript and metabolite profiles and enzyme activities are consistent in demonstrating a specialization process ofcotton fiber development toward cellulose synthesis. These data demonstrate that cotton fiber cell at a certain stage has itsown unique feature, and developmental stages of cotton fiber cells can be distinguished by their transcript and metaboliteprofiles. During the secondary cell wall synthesis stage, metabolic pathways are streamed into cellulose synthesis.

Terpenoids play important roles in plant-insect,plant-pathogen,and plant-plant interactions. Some terpenoids are of medicinal value,such as the anti-malaria drug Qinghaosu (artemisinin) which is an endoperoxide sesquiterpene lactone isolated from the traditional herb Artemisia annua. Sesquiterpenes are derived from the cytosolic mevalonate pathway,and sesquiterpene synthases catalyze the key step of converting faraesyl diphosphate into mostly cyclic *** plants expression of sesquiterpene synthase genes is often inducible by the phytohormone jasmonate(JA).We found that in ***,the JA-responsive AP2 family transcription factors—AaERF1 and AaERF2 are involved in transcriptional regulation of AaADS(encoding amorpha-4,11-diene synthase) and CYP71AV1 of the artemisinin *** Arabidopsis thaliana,the bHLH transcription factor MYC2 plays an important role in transcriptional regulation of AtTPS21 and AtTPS11,both are responsible for floral production of volatile ***,in addition to JA, the growth regulator gibberellin(GA) is also able to induce the AtTPS21 and AtTPS11 ***2 interacts with DELLA proteins which are GA signaling repressors, integrating both GA and JA signals into transcriptional regulation of sesquiterpene synthase *** that secondary metabolites vary among different organs and along with the plant life cycle,further research will be directed to explore the relationship between plant development and secondary metabolism regulation.

芍药为我国的传统名花,但在花境中应用极少。运用BIB-LCJ法,通过让不同专业背景的4个群体150名评价者,对芍药花期时不同类型植物景观照片的21个样本进行美景度评价,以探索公众所喜爱的芍药花境植物景观及其配植方法。研究表明,4个群体的审美标准相互之间都具有高度相关性,其中背景相似的人相关性更高。各群体的审美标准有一定差异,其中具有专业背景的人群审美能力更强,且各群体有不同的审美趋向。公众普遍对于植物种类丰富、色彩和谐、层次分明、线条感强、芍药种植面积大的样本评分较高,对植被覆盖度低、色彩杂乱、层次模糊、芍药突显性弱的样本评分较低。研究认为,在芍药花境的植物配植中,应契合公众的审美趋向,遵循基本的形式美法则,以求色彩、立面、质地的设计获得人们的青睐。

为了解国内鲜切荷花的市场潜力以及人们对鲜切荷花的需求和偏好,针对荷花的颜色、花态、花色、花型等观赏特征和购买鲜切荷花的主要目的等设计问卷,采取线上、线下调查相结合的方式收集有效数据问卷1 691份,使用Excel数据处理系统进行分析。结果表明:线上和线下调查的结果基本一致,女性参与调查率(77%)远高于男性(23%);作答者文化程度普遍较高;公司职员参与度较高。大部分人(62.1%)愿意购买荷花切花,说明我国荷花切花市场潜力巨大;在观赏特性上,人们偏好红绿色卵圆锥形或红色卵球形的花蕾;更喜爱半重瓣或重瓣、复色、碗状的荷花;清香、淡香型荷花更受欢迎;购买方式及用途上,单独购买居多,主要用于室内观赏;每支鲜切荷花5～10元的价格接受度最高;瓶插寿命短和市场上少见是当前制约荷花切花发展的主要因素。研究结果为我国以后开展鲜切荷花品种的筛选和培育、荷花切花的生产销售和市场开发提供了重要参考。
