Phytohalomonas tamaricis gen. nov., sp. nov., an endophytic bacterium isolated from Tamarix ramosissima roots growing in Kumtag desert.

A gram-stain-negative, aerobic, non-spore-forming, rod-shaped, non-motile bacterium strain R4HLG17 was isolated from Tamarix ramosissima roots growing in Kumtag desert. The strain grew at salinities of 0-16% (w/v) NaCl (optimum 5-6%), pH 5-9 (optimum 7) and at 16-45 °C. Based on 16S rRNA gene sequence similarity, strain R4HLG17 belonged to the family Halomonadaceae and was most closely related to Halomonas lutea DSM 23508(95.

Global Methylomic and Transcriptomic Analyses Reveal the Broad Participation of DNA Methylation in Daily Gene Expression Regulation of .

Changes in DNA methylation patterns in different tissues, at various developmental stages, and under environmental stimuli have been investigated in plants. However, the involvement of DNA methylation in daily gene expression regulation and the plant circadian clock have not been reported. Here, we investigated DNA methylomes and mRNA transcriptomes from leaves of over 24 h by high-throughput sequencing.

Sphingomonas deserti sp. nov., isolated from Mu Us Sandy Land soil.

A Gram-stain-negative, rod-shaped bacterium, designated as strain GL-C-18, was isolated from soil sample collected at Mu Us Sandy Land, China, and its taxonomic position was investigated using a polyphasic approach. Growth was observed in the presence of 0-1 % (w/v) NaCl (optimum, 0 %), pH 6.0-9.

Phyllobacterium phragmitis sp. nov., an endophytic bacterium isolated from Phragmites australis rhizome in Kumtag Desert.

A Gram-negative rod, designated strain 1N-3, was isolated from a rhizome of Phragmites australis grown in Kumtag Desert, China. Phylogenetic analysis showed that the strain is closely related to Phyllobacterium salinisoli LMG 30173 with 99.0% sequence similarity in the 16S rRNA gene and 92.

Zobellella endophytica sp. nov., isolated from the roots of Phragmites communis in the Kumtag Desert.

A Gram-negative, aerobic, non-spore-forming, rod-shaped, motile bacterium, named strain 59N8, was isolated from Phragmites communis roots in the Kumtag Desert. Phylogenetic analysis based on the 16S rRNA gene sequence showed that the isolate belongs to the genus Zobellella within the family Aeromonadaceae. The analysis showed that strain 59N8 was most closely related to Zobellella taiwanensis ZT1.

Mesorhizobium ephedrae sp. nov. isolated from the roots of Ephedra przewalskii in Kumtag desert.

Strain 6GN-30, a Gram-stain-negative, aerobic, non-spore-forming, rod-shaped, motile bacterium was isolated from Ephedra sinica roots in the Kumtag Desert. On the basis of the 16S rRNA gene sequence, the isolate represented a member of the genus Mesorhizobium of the family Phyllobacteriaceae. The results of a phylogenetic analysis indicated that 6GN-30 was phylogenetically related to Mesorhizobium soliNHI-8.

Sphingobacterium haloxyli sp. nov., an endophytic bacterium isolated from Haloxylon ammodendron stems in Kumtag desert.

A Gram-stain-negative, non-motile, aerobic, non-spore-forming, rod-shaped, bacterial strain, designated 5JN-11, was isolated from Haloxylonammodendron stems in Kumtag desert, Xinjiang province, China. Strain 5JN-11 grew at salinities of 0-6 % (w/v; optimum 0-2 %), a pH of 7.0-9.

Comparative Analyses of Anatomical Structure, Phytohormone Levels, and Gene Expression Profiles Reveal Potential Dwarfing Mechanisms in Shengyin Bamboo ( f. ).

Moso bamboo () is one of the most important bamboo species in China and the third most important plant species for timber production. However, the dwarf variant of moso bamboo, f. (shengyin bamboo), which has shortened internodes, is not well studied.

Genome-wide analysis of day/night DNA methylation differences in Populus nigra.

DNA methylation is an important mechanism of epigenetic modification. Methylation changes during stress responses and developmental processes have been well studied; however, their role in plant adaptation to the day/night cycle is poorly understood. In this study, we detected global methylation patterns in leaves of the black poplar Populus nigra 'N46' at 8:00 and 24:00 by methylated DNA immunoprecipitation sequencing (MeDIP-seq).
