Nitrogen Fertilizers Affect Microbial Hitchhiking to the Plant Roots

Journal of Agricultural and Food Chemistry (2024)

Zhibin Liu Qini Xia Jing Cai Ziyuan Wang Kexin Yang

The phenomenon of microbial hitchhiking, where nonmotile microbes utilize transspecies motility to navigate within their environment, has been observed. However, the underlying factors driving microbial hitchhiking remain unclear. Our study explored how nitrogen fertilizers affect microbial hitchhiking in soil through an in situ planting experiment. We established twelve treatments encompassing the presence and absence of plants, the presence and absence of a filter membrane that is used to prevent hitchhiking, and three nitrogen levels. Results showed that nitrogen influenced bacterial diversity in all soils, an effect thwarted by filter membranes. In the presence of plants, nitrogen significantly affected the bacterial mobility, Bacillus abundance, and plant biomass, but these effects vanished when filters were used. The correlation between motile Bacillus and rhizosphere bacteria was strong without filters at the proper nitrogen levels but weakened with membrane treatments. Thus, plants and nitrogen together, not nitrogen alone, alter the soil microbiome via hitchhiking.

The phylogeny of Seseli (Apiaceae, Apioideae): insights from molecular and morphological data

BMC Plant Biology (2022)

Jing Cai Huan-Huan Qin Jia-Qing Lei Chang‐Kun Liu Xing‐Jin He

The genus Seseli L., which consists of 125-140 species distributed in the Old World from western Europe and northwestern Africa to China and Japan, is one of the largest and most taxonomically difficult genera of Apiaceae Lindl. Although several previous studies have been conducted on Seseli based on limited morphological characteristics and molecular fragments, a robust and comprehensive phylogeny of Seseli remains elusive. Plastomes provide abundant genetic information and have been widely used in studying plant phylogeny and evolution. Consequently, we newly generated the complete plastomes of eleven Seseli taxa. We combined plastome data and morphological characteristics to investigate the phylogeny of Seseli.In our study, we observed that the genome length, gene numbers, IR/SC borders, and repeat composition of the eleven Seseli plastomes were variable. Several appropriate mutation hotspot regions may be developed as candidate DNA barcodes for evolution, phylogeny, and species identification of Seseli. The phylogenetic results identified that Seseli was not a monophyletic group. Moreover, the eleven newly sequenced Seseli taxa did not cluster with S. tortuosum (the type species of Seseli, belonging to the tribe Selineae), where S. delavayi clustered with Eriocycla belonging to the tribe Echinophoreae and the other ten belonged to Selineae. The comparative plastome and morphological characteristics analyses confirmed the reliability of the phylogenetic analyses and implied the complex evolution of Seseli.Combining molecular and morphological data is efficient and useful for studying the phylogeny of Seseli. We suggest that "a narrow sense" of Seseli will be meaningful for further study and the current taxonomic system of Seseli needs to be revised. In summary, our study can provide new insights into the phylogenetic relationships and taxonomic framework of Seseli.

Peer Review #2 of "Comparative study on the composition of four different varieties of garlic (v0.2)"

Cun Chen Jing Cai Songqin Liu Guo-liang Qiu Xiaogang Wu

Garlic is used as a medicinal seasoning worldwide.The aim of this work was to compare four varieties of garlic: 'Taicangbaipi', 'Ershuizao', 'Hongqixing', and 'Single-clove'，among them, 'Ershuizao' and 'Hongqixing' are unique to Sichuan Province of China.Firstly, soluble sugar, starch, and the protein content of the garlic were analyzed.There was more soluble sugar in 'Single-clove', total starch in 'Hongqixing', and protein content in 'Ershuizao' relative to the other three varieties, respectively.Gas chromatography-mass spectrometry (GC-MS) analysis showed that 'Ershuizao' and 'Hongqixing' contained high levels of 5-Hydroxymethylfurfural, which has antitumor, antioxidant, and cytoprotective effects.Indeed, the extracts from these two types of garlic were more effective at inhibiting tumor growth than that from the others.Moreover, the sulfide content and antimicrobial effects of 'Ershuizao' and 'Hongqixing' garlic were also higher than those of the other two types of garlic.In addition, changes observed in the membrane permeability and protein leakage suggest that the antimicrobial activity of the 'Ershuizao' and 'Hongqixing' extracts may be due to the destruction of the structural integrity of the cell membranes, leading to cell death.

Ligusticopsis miyiensis (Apioideae, Apiaceae), a new combination from China revealed by morphological and molecular evidence

Phytotaxa (2023)

Jia-Qing Lei Jing Cai Song‐Dong Zhou Xing‐Jin He

Ligusticum glaucescens (Apioideae, Apiaceae) found in China, is a poorly known species known only from the type collection. The species was considered to belong to Kitagawia. In our morphological examination, Ligusticum glaucescens is more morphologically consistent with Ligusticopsis than Kitagawia. Furthermore, several morphological characteristics of Ligusticum glaucescens can also easily distinguish this species from other validated Ligusticopsis species. Phylogenetic analyses based on plastome and nrDNA sequences revealed that Ligusticum glaucescens is distant from Kitagawia but nested in Ligusticopsis. As both morphological and phylogenetic evidence supported the inclusion of Ligusticum glaucescens within Ligusticopsis, this species is here transferred, and a new combination, Ligusticopsis miyiensis, is proposed.
