The necrotrophic fungus, Sclerotinia sclerotiorum, employs an array of cell wall-degrading enzymes(CWDEs), including cellulase, to dismantle host cell walls. However, the molecular mechanisms through which S. sclerotiorum degrades cellulose remain elusive. Here, we unveil a novel secretory cellobiohydrolase, SsdchA, characterized by a signal peptide and a Glyco_hydro_7(GH7) domain. SsdchA exhibits a robust expression of during early infection stages. Interestingly, colony morphology and growth rates remain unaffected across the wild-type, SsdchA deletion strains and SsdchA overexpression strains on potato dextrose agar(PDA) medium. Nevertheless, the pathogenicity and cellobiohydrolase activity decreased in the SsdchA deletion strains, but enhanced in the SsdchA overexpression strains. Moreover,the heterologous expression of SsdchA in Arabidopsis thaliana leads to reduced cellulose content and heightened susceptibility to S. sclerotiorum. Collectively, our data underscore the pivotal role of the novel cellobiohydrolase SsdchA in the pathogenicity of S. sclerotiorum.

A proper dietary electrolyte balance(dEB) is essential to ensure optimal growth performance of piglets. In the low-protein diet, this balance may be affected by the reduction of soybean meal and the inclusion of high levels of synthetic amino acids. The objective of this experiment was to evaluate the optimal dEB of low-protein diets and its impact on the growth performance of piglets. A total of 108 piglets(initial age of35 d) were randomly divided into 3 groups with 6 replicates of 6 pigs each as follows: low electrolyte diet(LE group; dEB = 150 milliequivalents [mEq]/kg); medium electrolyte diet(ME group; dEB = 250 m Eq/kg);high electrolyte diet(HE group; d EB = 350 mEq/kg). Results indicated that the LE and HE diet significantly decreased the average daily gain, average daily feed intake, and crude protein digestibility(P < 0.05) in piglets. Meanwhile, LE diets disrupted the structural integrity of the piglets' intestines and decreased jejunal tight junction protein(occludin and claudin-1) expression(P < 0.05). Additionally, the pH and HCO3 in the arterial blood of piglets in the LE group were lower than those in the ME and HE groups(P < 0.05).Interestingly, the LE diet significantly increased lysine content in piglet serum(P < 0.05), decreased the levels of arginine, leucine, glutamic acid, and alanine(P < 0.05), and inhibited the mammalian target of rapamycin complex 1(mTORC1) pathway by decreasing the phosphorylation abundance of key proteins. In summary, the dietary electrolyte imbalance could inhibit the activation of the mTORC1 signaling pathway,which might be a key factor in the influence of the dEB on piglet growth performance and intestinal ***, second-order polynomial(quadratic) regression analysis showed that the optimal dEB of piglets in the low-protein diet was 250 to 265 mEq/kg.
