Indole enhances the survival of Pantoea ananatis YJ76 in face of starvation conditions
Pantoea ananatis YJ76 is an indole‐producing predominant diazotrophic endophyte isolated from rice having multiple growth‐promoting effects on host plant. As a decomposition metabolite of L‐tryptophan (L‐Trp), indole is confirmed to regulate various physiological processes of bacteria. In this research, we found that indole significantly improves the survival of YJ76 in face of starvation conditions and the promoting effect is related to the glycogen accumulation promoted by indole, which is much more significant in the middle decline phase than in other growth phases. Since carbon storage regulator CsrA is a key i...

Cloning and analysis of the Glwc ‐1 and Glwc‐2 genes encoding putative blue light photoreceptor from Ganoderma lucidum
Blue light plays an important role during the growth of Ganoderma lucidum, one of the best‐known medicinal macrofungi in China. In the present study, we cloned Glwc‐1 and Glwc‐2, the homologue of the blue light photoreceptors Ncwc‐1 and Ncwc‐2 of Neurospora crassa, from G. lucidum. The deduced amino acid sequence of Glwc‐1 contained the similar function domains as NcWC‐1 including LOV, PAS B, PAS C, and PAC domains. The deduced amino acid sequence of Glwc‐2 contained PAS domain and GATA‐type zinc finger (Znf) domain as well as NcWC‐2. Phylogenetic analysis based on fungal WC‐1 and WC‐2 supported GlW...

Emergent macrophytes modify the abundance and community composition of ammonia oxidizers in their rhizosphere sediments
Ammonia oxidation is a crucial process in global nitrogen cycling, which is catalyzed by the ammonia oxidizers. Emergent plants play important roles in the freshwater ecosystem. Therefore, it is meaningful to investigate the effects of emergent macrophytes on the abundance and community composition of ammonia oxidizers. In the present study, two commonly found emergent macrophytes (Zizania caduciflora and Phragmitas communis) were obtained from freshwater lakes and the abundance and community composition of the ammonia‐oxidizing prokaryotes in the rhizosphere sediments of these emergent macrophytes were investigated. The...
