| 1 | Asplenium sanshuiense sp. nov.:the Lowest Latitude Fossil Record of the Genus显示文摘Extant Asplenium is one of the most widespread fern groups and occurs in the temperate and tropical regions.However,the fossil records of this genus are poorly documented,especially in the low latitudes.Here,a new species,Asplenium sanshuiense sp.nov.is described from the early Eocene of Sanshui Basin,Guangdong Province,South China.This is the lowest modern latitude fossil record of Asplenium and the first fossil assignment of A.section Darea(Jussieu) Bak.,as well as the first fossil record of Asplemum reported from South China.This new species shows that Asplenium had already spread into South China by the early Eocene and the section Darea(Jussieu) Bak.was identifiable within the genus Asplenium during that time.This new species,combined with previous fossil spore-pollen records indicates a warm and humid climate in the Sanshui Basin of the early Eocene. | XU Kewang LIAO Wenbo JIN Jianhua LIU Xiaoyan | 2017 | Acta Geologica Sinica(English Edition)2017，91，4： | 0 |
| 2 | The first mitogenome of Lauraceae(Cinnamomum chekiangense)显示文摘There are three distinct genetic systems in higher plants,the dominant nuclear genome and the semi-autonomous organelle genomes(plastids and mitochondria).In contrast to the conserved plastid genome(plastome),the plant mitochondrial genome(mitogenome)is characterized by an intriguing“evolutionary paradox”distinguished by a remarkably low mutation rate but with a significantly high rearrangement rate(Palmer and Herbon,1988;Lai et al.,2022). | Changwei Bi Ning Sun Fuchuan Han Kewang Xu Yong Yang David K.Ferguson | 2024 | Plant Diversity2024，46，1： | 0 |
