A strain of the white-capped form of the common cultivated mushroom, Psalliota hortensis (Cook;e,} Lange forma albida Lange, appeared unable to grow appreciably on a liquid basal medium which contained glucose, asparagine, and mineral salts. Addition of thiamin and biotin increased the growth a little . .A number of other vitamins were without effect. Indole-3-acetic acid (IAA) in concentrations of from 5 to 100 mg/l markedly increased growth, particularly in the presence of thiamin and biotin, but only when the inoculum was floating on the surface of the culture medium. If the inoculum was submerged, addition of IAA had very little effect. The growth of both floating and submerged

AbstractThe aim of this study was to investigate whether supplementing branched-chain amino acids (AA) (BCAA) along with a reduced-protein diet increases piglet growth, and whether elevated feed intake and muscle growth-promoting effect contribute to this improvement. In Expt 1, twenty-eight weanling piglets were randomly fed one of the following four diets: a positive control (PC) diet, a reduced-protein negative control (NC) diet, an NC diet supplemented with BCAA to the same levels as in the PC diet (test 1 (T1)) and an NC diet supplemented with a 2-fold dose of BCAA in T1 diet (test 2 (T2)) for 28 d. In Expt 2, twenty-one weanling piglets were randomly assigned to NC, T1 and pair-fed T1 (P) groups. NC and T1 diets were the same as in Expt 1, whereas piglets in the P group were individually pair-fed with the NC group. In Expt 1, the NC group had reduced piglet growth and feed intake compared with the PC group, which were restored in T1 and T2 groups, but no differences were detected between T1 and T2 groups. In Expt 2, T1 and P groups showed increases in growth and mass of some muscles compared with the NC group. Increased feed intake after BCAA supplementation was associated with increased mRNA expressions of agouti-related peptide and co-express neuropeptide Y (NPY) and phosphorylation of mammalian target of rapamycin (mTOR) and ribosomal protein S6 kinase 1 (S6K1), as well as decreased mRNA expressions of melanocortin-4 receptor and cocaine- and amphetamine-regulated transcript and phosphorylation of eukaryotic initiation factor 2α in the hypothalamus. No differences were observed among PC, T1 and T2 groups except for higher NPY mRNA expression in the T2 group than in the PC group (Expt 1). Phosphorylation of mTOR and S6K1 in muscle was enhanced after BCAA supplementation, which was independent of change in feed intake (Expt 2). In conclusion, supplementing BCAA to reduced-protein diets increases feed intake and muscle mass, and contributes to better growth performance in piglets.

Abstract Rumex gmelinii Turcz. (RGT) is a medicinal plant of Rumex in Polygonaceae. Our research group isolated an endophytic fungus plectosaphaerella cucumerina (Strain J-G) from RGT, which could promote the growth of the host significantly when was co-cultured with the host. In this study, we mainly used transcriptomic analysis to explore the molecular mechanism of the growth promoting effect. It was found that during the process of co-culture with Strain J-G, metabolism of amino acids, the synthesis and metabolism of carbohydrates in RGT tissue culture seedlings were all promoted, which provided sufficient material and energy basis for the growth of plants. In addition, response to hormones such as auxin and cytokinin in RGT tissue culture seedlings was improved significantly, which promoted the growth and development of plants. The repairing ability of DNA in RGT tissue culture seedlings was also enhanced to provide a good guarantee for the growth of plants. Meanwhile, defense system of RGT tissue culture seedlings was also mobilized by the existence of Strain J-G, therefore more secondary metabolites and stress resistant substances were produced to ensure the normal growth and metabolism of plants.
