Molecular Diversity of Microbes Associated with Fermented Bamboo Shoots.

ABSTRACT: Fermented bamboo shoots are rich in high protein, carbohydrates, fibre and minerals while low in fat content. In the North-East region of India and other Asian countries, they are mostly used in various food preparations. The present study was undertaken to explore the diversity of bacteria associated with Bamboo shoots and to evaluate their antibacterial profile. Based on the results the fermented bamboo shoots showed viable counts ranging from 6.55 ± 0.91 log CFU/g to 7.86 ± 1.21 log CFU/g. The 16s rRNA sequence analysis showed that these isolates belonged to the genus Bacillus (Bacillus safensis, B. tequilensis, B. siamensis, B. nakamurai, B. subtilis) and Enterobacter. These isolates have not been reported previously from fermented bamboo shoots except B. subtilis. Surprisingly, no Lactobacillus species or molds were found in any of the samples tested. Potent antibacterial activity was recorded against Klebsiella, Staphylococcus aureus, Salmonella and B. cereus.

Project description:: Homeobox (HB) genes play critical roles in regulating various aspects of plant growth and development. However, little is known about HB genes in bamboo. In this study, a total of 115 HB genes (PeHB001‒PeHB115) were identified from moso bamboo (Phyllostachys edulis) and grouped into 13 distinct classes (BEL, DDT, HD-ZIP I‒IV, KNOX, NDX, PHD, PINTOX, PLINC, SAWADEE, and WOX) based on the conserved domains and phylogenetic analysis. The number of members in the different classes ranged from 2 to 24, and they usually varied in terms of exon‒intron distribution pattern and length. There were 20 conserved motifs found in 115 PeHBs, with motif 1 being the most common. Gene ontology (GO) analysis showed that PeHBs had diverse molecular functions, with 19 PeHBs being annotated as having xylem development, xylem, and phloem pattern formation functions. Co-expression network analysis showed that 10 of the 19 PeHBs had co-expression correlations, and three members of the KNOX class were hub proteins that interacted with other transcription factors (TFs) such as MYB, bHLH, and OVATE, which were associated with lignin synthesis. Yeast two-hybridization results further proved that PeHB037 (BEL class) interacted with PeHB057 (KNOX class). Transcriptome expression profiling indicated that all PeHBs except PeHB017 were expressed in at least one of the seven tissues of moso bamboo, and 90 PeHBs were expressed in all the tissues. The qRT-PCR results of the 19 PeHBs showed that most of them were upregulated in shoots as the height increased. Moreover, a KNOX binding site was found in the promoters of the key genes involved in lignin synthesis such as Pe4CL, PeC3H, PeCCR, and PeCOMT, which had positive expression correlations with five KNOX genes. Similar results were found in winter bamboo shoots with prolonged storage time, which was consistent with the degree of lignification. These results provide basic data on PeHBs in moso bamboo, which will be helpful for future functional research on PeHBs with positive regulatory roles in the process of lignification.
