| 1 | Genetic basis of high aroma and stress toleranee in the oolong tea cultivar genome显示文摘Tea plants(Camellia sinensis)are commercially cultivated in>60 countries,and their fresh leaves are processed into tea,which is the most widely consumed beverage in the world.Although several chromosome-level tea plant genomes have been published,they collapsed the two haplotypes and ignored a large number of allelic variations that may underlie important biological functions in this species.Here,we present a phased chromosome-scale assembly for an elite oolong tea cultivar,'Huangdan',that is well known for its high levels of aroma.Based on the two sets of haplotype genome data,we identi fi ed numerous genetic variations and a substantial proportion of allelic imbalance related to important traits,including aroma-and stress-related alleles.Comparative genomics revealed extensive structural variations as well as expansion of some gene families,such as terpene synthases(TPSs),that likely contribute to the high-aroma characteristics of the backbone parent,underlying the molecular basis for the biosynthesis of aroma-related chemicals in oolong tea.Our results uncovered the genetic basis of special features of this oolong tea cultivar,providing fundamental genomic resources to study evolution and domestication for the economically important tea crop. | Pengjie Wang Jiaxin Yu Shan Jin Shuai Chen Chuan Yue Wenling Wang Shuilian Gao Hongli Cao Yucheng Zheng Mengya Gu Xuejin Chen Yun Sun Yuqiong Guo Jiangfan Yang Xingtan Zhang Naixing Ye | 2021 | Horticulture Research2021，8，1： | 4 |
| 2 | Chromatin accessibility and translational Iandscapes of tea plants under chilling stress显示文摘Plants have evolved regulatory mechanisms at multiple levels to regulate gene expression in order to improve their cold adaptability.However,limited information is available regarding the stress response at the chromatin and translational levels.Here,we characterize the chromatin accessibility,transcriptional,and translational landscapes of tea plants in vivo under chilling stress for the first time.Chilling stress signi ficantly affected both the transcription and translation levels as well as the translation efficiency of tea plants.A total of 3010 genes that underwent rapid and independent translation under chilling stress were observed,and they were signi ficantly enriched in the photosynthesis-antenna protein and phenylpropanoid biosynthesis pathways.A set of genes that were signi ficantly responsive to cold at the transcription and translation levels,including four(+)-neomenthol dehydrogenases(MNDs)and two(E)-nerolidol synthases(NESs)arranged in tandem on the chromosomes,were also found.We detected potential upstream open reading frames(uORFs)on 3082 genes and found that tea plants may inhibit the overall expression of genes by enhancing the translation of uORFs under chilling stress.In addition,we identi fied distal transposase hypersensitive sites(THSs)and proximal THSs and constructed a transcriptional regulatory network for tea plants under chilling stress.We also identi fied 13 high-con fidence transcription factors(TFs)that may play a crucial role in cold regulation.These results provide valuable information regarding the potential transcriptional regulatory network in plants and help to clarify how plants exhibit flexible responses to chilling stress. | Pengjie Wang Shan Jin Xuejin Chen Liangyu Wu Yucheng Zheng Chuan Yue Yongchun Guo Xingtan Zhang Jiangfan Yang Naixing Ye | 2021 | Horticulture Research2021，8，1： | 2 |

| 5 | Homogeneous distributed natural pyrite-derived composite induced by modified graphite as high-performance lithium-ion batteries anode显示文摘Natural minerals-based energy materials have attracted enormous attention because of the advantages of good materials consistency,high production,environmental friendliness,and low cost.The uniform distribution of grains can effectively inhibit the aggregation of active materials,improving lithium storage performance.In this work,natural graphite is modified by polyvinylpyrrolidone to obtain modified graphite with reduced size and better dispersion.Natural pyrite composite polyvinylpyrrolidone-modified graphite(pyrite/PG)material with uniform particle distribution is obtained by the ball milling process.The subsequent calcination process converts pyrite/PG into Fe_(1-x)Scompounded with polyvinylpyrrolidone-modified graphite(Fe_(1-x)S/PG).The homogeneous grain distributions of active material can facilitate the faster transfer of electrons and promote the efficient utilization of active materials.The as-prepared Fe_(1-x)S/PG electrode exhibits a remarkably reversible specific capacity of 613.0 mAh·g^(-1)at 0.2 A·g^(-1)after 80 cycles and an excellent rate capability of 523.0 mAh·g^(-1)at 5 A·g^(-1).Even at a higher current density of 10 A·g^(-1),it can deliver a specific capacity of 348.0 mAh·g^(-1).Moreover,the dominant pseudocapacitance in redox reactions accounts for the impressive rate and cycling stability.This work provides a low-cost and facile method to fabricate natural mineral-based anode materials and apprise readers about the impact of uniform particle distribution on lithium storage performance. | Juan Yu Yinbo Wei Bicheng Meng Jiaxin Peng Kai Yang Tianxing Chen Naixing Yang Xiuyun Chuan | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，7： | 0 |
