    Abstract Winter mulching is widely used to raise soil temperature and promote earlier harvesting in agroforestry, but successive years of mulching can lead to soil degradation. The effect of winter mulch on soil bacterial community composition and co‐occurrence patterns is not clear. The influence of different mulches (a defatted seed cake of Camellia oleifera, DS; a mixture of wheat straw and chicken manure, MWC; and wheat straw, WS) on soil bacterial communities and networks in lei bamboo (Phyllostachys praecox) forests over a four‐month mulching period was studied using Illumina sequencing of the 16S rRNA gene. The results showed that mulching time and mulching material treatment significantly influenced bacterial community composition and diversity, mainly driven by nutrient availability. MWC and WS mulching treatments decreased α‐diversity of the bacterial communities, whereas the DS treatment had no significant impact. The oligotrophs, Gryllotalpicola, Granulicella, and Verrucomicrobia, were enriched before and at the end of mulching, while the copiotrophs, Deltaproteobacteria, were enriched in the middle of the mulching period (Jan). Comparing the three mulching treatments, Proteobacteria were enriched in DS mulching soils in Jan. The complexity of the four networks decreased with pre‐mulching, DS mulching, WS mulching, and MWC mulching networks, with a reduction in the number of edges and average degree observed. The results suggested that winter mulching practices adversely affected soil bacterial community diversity and interactions, which may be detrimental to the resistance of bacterial communities to environmental changes and soil sustainability. Mulching MWC and WS has a greater risk of loss of soil bacterial biodiversity than DS.

    Abstract Lei bamboo (Phyllostachys violascens) shoots are delicious food in Asia. Here, the molecular basis of lignification in postharvest Lei bamboo shoots under low temperature (LT) is revealed by transcriptomic and metabolomics analyses for the first time. We identified substantial accumulations of jasmonates (JAs) and major lignin biosynthesis precursors (coumarin, trans-4-coumaric acid, trans-ferulic acid and L-phenylalanine). Transcriptome analysis indicated that some regulatory genes were significantly differentially expressed, and the expression patterns of them were highly consistent with the changes in the key lignin precursors or JA profiles. Co-expression analysis showed that the LT responsive genes PvCRPK-4/-5, PvICE2-1/2, PvDREB2B might form a network module with the lignin (PvC3H-2/3, PvC4H-2/4, PvCAD-1/2/3/4, etc.) or JA biosynthesis genes (PvOPR2, PvJAZ-4 and PvPEX5, etc.), indicating a LT-lignification or LT-JA-lignification regulatory pathway in Lei bamboo shoots. Above all, our findings provide new an insight into the LT-associated lignification in postharvest bamboo shoots.

    Abstract This study analyzed cored sediments retrieved from sites distributed across a transect of the Lei-Gong-Hou mud volcanoes in eastern Taiwan to uncover the spatial distributions of biogeochemical processes and community assemblages involved in methane cycling. The profiles of methane concentration and carbon isotopic composition revealed various orders of the predominance of specific methane-related metabolisms along depth. At a site proximal to the bubbling pool, the methanogenic zone was sandwiched by the anaerobic methanotrophic zones. For two sites distributed toward the topographic depression, the methanogenic zone overlaid the anaerobic methanotrophic zone. The predominance of anaerobic methanotrophy at specific depth intervals is supported by the enhanced copy numbers of the ANME-2a 16S rRNA gene and coincides with high dissolved Fe/Mn concentrations and copy numbers of the Desulfuromonas/Pelobacter 16S rRNA gene. Assemblages of 16S rRNA and mcrA genes revealed that methanogenesis was mediated by Methanococcoides and Methanosarcina. pmoA genes and a few 16S rRNA genes related to aerobic methanotrophs were detected in limited numbers of subsurface samples. While dissolved Fe/Mn signifies the presence of anaerobic metabolisms near the surface, the correlations between geochemical characteristics and gene abundances, and the absence of aerobic methanotrophs in top sediments suggest that anaerobic methanotrophy is potentially dependent on iron/manganese reduction and dominates over aerobic methanotrophy for the removal of methane produced in situ or from a deep source. Near-surface methanogenesis contributes to the methane emissions from mud platform. The alternating arrangements of methanogenic and methanotrophic zones at different sites suggest that the interactions between mud deposition, evaporation, oxidation and fluid transport modulate the assemblages of microbial communities and methane cycling in different compartments of terrestrial mud volcanoes.

    Abstract In the post-genome era, great progress has been made in metabolic engineering using recombinant DNA technology to enhance the production of high-value products by Streptomyces. With the development of microbial genome sequencing techniques and bioinformatic tools, a growing number of secondary metabolite (SM) biosynthetic gene clusters in Streptomyces and their biosynthetic logics have been uncovered and elucidated. In order to increase our knowledge about transcriptional regulators in SM of Streptomyces, this review firstly makes a comprehensive summary of the characterized factors involved in enhancing SM production and awakening SM biosynthesis. Future perspectives on transcriptional regulator engineering for new SM biosynthesis by Streptomyces are also provided.
