Decomposition time,chemical traits and climatic factors determine litter-mixing effects on decomposition in an alpine steppe ecosystem in Northern Tibet

Plant and Soil - In the context of rapid species diversity loss, whether and how species diversity affects litter decomposition in alpine ecosystems remain unclear. Here, we aimed to assess the...     

Intermittent high glucose induces pyroptosis of rat H9C2 cardiomyocytes via sodium–glucose cotransporter 1

Molecular and Cellular Biochemistry - Cardiomyocyte death is an important pathogenic process in cardiac complications of diabetes. Diabetic patients often suffer glycemic variability. Pyroptosis is...     

An in-depth analysis reveals two new genetic variants on 22q11.2 associated with vitiligo in the Chinese Han population

Molecular Biology Reports - Vitiligo is a complex disease in which patchy depigmentation is the result of an autoimmune-induced loss of melanocytes in affected regions. On the basis of a...

β-1,6葡聚糖酶前体编码基因Ss4p对甘蔗黑穗病菌分泌蛋白组的影响

甘蔗(Saccharum spp.)是世界也是中国主要的糖料作物.由甘蔗黑穗病菌(Sporisorium scitamineum)引起的甘蔗黑穗病是中国甘蔗生产上最主要的病害,每年造成重大损失.分泌蛋白在真菌侵染寄主植物与获取营养及病理过程起重要作用.本实验室在分析甘蔗黑穗病菌基因组与转录组数据时,发现1个与真菌细胞壁降解有关的β-1,6葡聚糖酶前体的基因Ssa4p.为了揭示Ssa4p对甘蔗黑穗病菌致病性和分泌蛋白组的影响,本研究利用CRISPR/Cas9和T-DNA双元载体所构建的甘蔗黑穗菌基因敲除系统,成功获得了Ssa4p基因的失活突变株.ΔSsa4p突变株(Δ35-Ssa4p)与野生型菌株JG36的配合能力降低且致病性减弱.用iTRAQ方法对Δ35-Ssa4p和野生型菌株的分泌蛋白组进行比较分析,共鉴定到蛋白质1430个,其中上调差异表达蛋白质685个,下调差异表达蛋白质745个.GO功能富集分析及KEGG分析表明,差异蛋白主要定位于无膜细胞器和核糖体,其功能包括参与核糖体、氨基糖和核苷酸糖代谢等生物学过程.本研究发现β-1,6葡聚糖前体影响植物病原真菌的分泌蛋白,加深了对真菌致病性调控机制的认识.
