| 1 | Combined genomic, transcriptomic, and metabolomic an alyses provide in sights into chayote (Sechium edule) evolution and fruit development显示文摘Chayote(Sechium edule)is an agricultural crop in the Cucurbitaceae family that is rich in bioactive components.To enhance genetic research on chayote,we used Nanopore third-generation sequencing combined with Hi-C data to assemble a draft chayote genome.A chromosome-level assembly anchored on 14 chromosomes(N50 contig and scaffold sizes of 8.40 and 46.56 Mb,respectively)estimated the genome size as 606.42 Mb,which is large for the Cucurbitaceae,with 65.94%(401.08 Mb)ofthe genome comprising repetitive sequences;28,237 protein-coding genes were predicted.Comparative genome analysis indicated that chayote and snake gourd diverged from sponge gourd and that a whole-genome duplication(WGD)event occurred in chayote at 25±4 Mya.Transcriptional and metabolic analysis revealed genes involved in fruit texture,pigment,fl avor,fl avonoids,antioxidants,and plant hormones during chayote fruit development.The analysis of the genome,transcriptome,and metabolome provides insights into chayote evolution and lays the groundwork for future research on fruit and tuber development and genetic improvements in chayote. | Anzhen Fu Qing Wang Jianlou Mu Lili Ma Changlong Wen Xiaoyan Zhao Lipu Gao Jian Li Kai Shi Yunxiang Wang Xuechuan Zhang Xuewen Zhang Fengling Wang Donald Grierson Jinhua Zuo | 2021 | Horticulture Research2021，8，1： | 6 |
| 2 | The genome and transcriptome analysis of snake gourd provide insights into its evolution and fruit development and ripening显示文摘Snake gourd(Trichosanthes anguina L.),which belongs to the Cucurbitaceae family,is a popular ornamental and food crop species with medicinal value and is grown in many parts of the world.Although progress has been made in its genetic improvement,the organization,composition,and evolution of the snake gourd genome remain largely unknown.Here,we report a high-quality genome assembly for snake gourd,comprising 202 contigs,with a total size of 919.8 Mb and an N50 size of 20.1 Mb.These findings indicate that snake gourd has one of the largest genomes of Cucurbitaceae species sequenced to date.The snake gourd genome assembly harbors 22,874 protein-coding genes and 80.0%of the genome consists of repetitive sequences.Phylogenetic analysis reveals that snake gourd is closely related to sponge gourd but diverged from their common ancestor~33–47 million years ago.The genome sequence reported here serves as a valuable resource for snake gourd genetic research and comparative genomic studies in Cucurbitaceae and other plant species.In addition,fruit transcriptome analysis reveals the candidate genes related to quality traits during snake gourd fruit development and provides a basis for future research on snake gourd fruit development and ripening at the transcript level. | Lili Ma Qing Wang Jianlou Mu Anzhen Fu Changlong Wen Xiaoyan Zhao Lipu Gao Jian Li Kai Shi Yunxiang Wang Xuewen Zhang Xuechuan Zhang Zhangjun Fei Donald Grierson Jinhua Zuo | 2020 | Horticulture Research2020，7，1： | 2 |
| 3 | Yield photosynthesis and leaf anatomy of maize in inter-and mono-cropping systems at varying plant densities显示文摘Increasing plant density can increase cereal crop yields. However, the physiological and anatomical mechanisms of grain yield increase at high plant densities in maize-based intercropping systems are not well understood. A two-year field experiment was conducted in 2018 and 2019 to investigate grain yield, photosynthetic characteristics, stomatal traits, and leaf anatomy of maize plants in an intercropping system with high plant densities. Two cropping patterns(monocropping and intercropping) and three plant densities(D1, 78,000 plants ha^(-1);D2, 103,500 plants ha^(-1);D3, 129,000 plants ha;were arranged in a randomized block design. Increasing maize plant density significantly increased maize yield, and intercropping gave a significant yield advantage over monocropping under the same plant density. Intercropping combined with high plant density increased the leaf area and SPAD value of maize,increasing the photosynthesis rates after the harvest of pea. At the twelfth leaf stage, the stomatal density and stomatal area of intercrops combined with medium plant density increased by respectively 10.5%and 18.4% relative to their values for the corresponding density of monocrops. Although leaf thickness of maize was reduced by increasing plant density, the chloroplast number and grana lamella number were higher in intercropping than in monocropping under different plant densities. These positive changes in leaf anatomy resulted in increased photosynthesis, suggesting a physiological basis for the increase in grain yield. | Hongwei Yang Qiang Chai Wen Yin Falong Hu Anzhen Qin Zhilong Fan Aizhong Yu Cai Zhao Hong Fan | 2022 | The Crop Journal2022，10，3： | 2 |
