| 1 | A high-quality genome assembly of Morinda officinalis,a famous native southern herb in the Lingnan region of southern China显示文摘Morinda officinalis is a well-known medicinal and edible plant that is widely cultivated in the Lingnan region of southern China.Its dried roots(called bajitian in traditional Chinese medicine)are broadly used to treat various diseases,such as impotence and rheumatism.Here,we report a high-quality chromosome-scale genome assembly of M.officinalis using Nanopore single-molecule sequencing and Hi-C technology.The assembled genome size was 484.85Mb with a scaffold N50 of 40.97 Mb,and 90.77%of the assembled sequences were anchored on eleven pseudochromosomes.The genome includes 27,698 protein-coding genes,and most of the assemblies are repetitive sequences.Genome evolution analysis revealed that M.officinalis underwent core eudicotγgenome triplication events but no recent whole-genome duplication(WGD).Likewise,comparative genomic analysis showed no large-scale structural variation after species divergence between M.officinalis and Coffea canephora.Moreover,gene family analysis indicated that gene families associated with plant–pathogen interactions and sugar metabolism were significantly expanded in M.officinalis.Furthermore,we identified many candidate genes involved in the biosynthesis of major active components such as anthraquinones,iridoids and polysaccharides.In addition,we also found that the DHQS,GGPPS,TPS-Clin,TPS04,sacA,and UGDH gene families—which include the critical genes for active component biosynthesis—were expanded in M.officinalis.This study provides a valuable resource for understanding M.officinalis genome evolution and active component biosynthesis.This work will facilitate genetic improvement and molecular breeding of this commercially important plant. | Jihua Wang Shiqiang Xu Yu Mei Shike Cai Yan Gu Minyang Sun Zhan Liang Yong Xiao Muqing Zhang Shaohai Yang | 2021 | Horticulture Research2021，8，1： | 4 |
| 2 | Discussion on the Mechanism of Boric Acid and Phosphoric Acid to Improve the Hardening of Complex Calcium Lubricating Grease显示文摘In order to solve the hardening problem of complex calcium lubricating grease, the water absorption test of several calcium salts was carried out, and it was found that calcium 12-hydroxystearate did not absorb water, and calcium acetate, calcium phosphate and calcium borate had different degrees of water absorption. Calcium acetate has the highest water absorption rate, while calcium phosphate and calcium borate show comparable water absorption rates. Upon using the molecular simulation technology, it is found that in the complex calcium grease system, calcium phosphate and calcium borate tend to combine with water, which inhibits the water absorption of calcium acetate and alleviate the hardening problem. | Zheng Hui Sun Hongwei He Yifeng Su Shuo Zhuang Minyang Liu Xinyang | 2019 | China Petroleum Processing & Petrochemical Technology2019，21，4： | 3 |
