A strain, named LCFJ-001 (GDMCC: 1.6101), was isolated for the first time from bacterial wilt-diseased roots of mulberry () in the western part of the Guangxi Zhuang Autonomous Region, China. Moreover, through Koch's postulates, it was proven that LCFJ-001 can cause mulberry wilt, which is one of the pathogens of mulberry bacterial wilt.

We developed FishPIE, a nested PCR primer set of 82 phylogenetically informative exon markers, and tested it on 203 species from 31 orders of Actinopterygii. We combined orthologous sequences of the FishPIE markers obtained from published genomes and transcriptomes and constructed the phylogeny of 710 species belonging to 190 families and 60 orders.

Controlling environmental pollutant discharge and water resource demand is crucial for the sustainable development of agriculture and rural areas in arid oases. Taking Ganzhou, an arid oasis in Northwest China, as an example, we established an analysis framework for the relationship between the planting industry transformation and the resource and environmental pressures, from 2011 to 2020, through the methods of inventory, coefficient and quota accounting. The results showed that the planting scale of crops in oases has continuously expanded, with a structural dominance of corn seed production.

Selection of beneficial genomic variants was crucial for regional adaptation of crops during domestication, but the underlying genomic basis remains largely unexplored. Here we report a genome-wide selective-sweep analysis of 655 japonica and 1,205 indica accessions selected from 2,673 landraces through principal component analysis to identify 5,636 non-synonymous single nucleotide polymorphisms (SNPs) fixed in at least one subspecies. We classified these SNPs into three groups, jiS (japonica- and indica-selected), jS (japonica-selected only), and iS (indica-selected only), and documented evidence for selection acting on these groups, their relation to yield-related traits, such as heading date, and their practical value in cropping area prediction.

These ciliates are morphologically very similar; hence, it is difficult to identify specific scuticociliate species using traditional classification methods for performing taxonomic research and disease control studies.
Methods: We annotated the mitochondrial genomes of these two scuticociliates on the basis of previous sequencing, including analyses of nucleotide composition, codon usage, Ka/Ks, and p-distance.

This paper aims to supplement chloroplast (cp) genomic resources and to be used in phylogenetic studies and identification of AV related plants.
Methods: High-throughput sequencing technology was used to determine the complete sequence of the AV cp genome, and the sequence was then compared with three related species.
Loblolly pine ( L.) is one of the most important species for oleoresin (a mixture of terpenoids) in South China. The high oleoresin content of loblolly pine is associated with resistance to bark beetles and other economic benefits.
