Project description:Wurfbainia villosa, which belongs to the huge family Zingiberaceae, is used in the clinic for the treatment of spleen and stomach diseases in southern China. The complete chloroplast genome of W. villosa was sequenced and analyzed using next-generation sequencing technology in the present work. The results showed that the W. villosa chloroplast genome is a circular molecule with 163,608 bp in length. It harbors a pair of inverted repeat regions (IRa and IRb) of 29,820 bp in length, which separate the large single copy (LSC, 88,680 bp) region and the small single copy (SSC, 15,288 bp) region. After annotation, 134 genes were identified in this plastome in total, comprising of 87 protein-coding genes, 38 transfer RNA genes, 8 ribosomal RNA genes and one pseudogene (ycf1). Codon usage, RNA editing sites and single/long sequence repeats were investigated to understand the structural characteristics of the W. villosa chloroplast genome. Furthermore, IR contraction and expansion were analyzed by comparison of complete chloroplast genomes of W. villosa and four other Zingiberaceae species. Finally, a phylogeny study based on the chloroplast genome of W. villosa, along with that of 15 different species, was conducted to further investigate the relationship among these lineages. Overally, our results represented the first insight into the chloroplast genome of W. villosa, and could serve as a significant reference for species identification, genetic diversity analysis and phylogenetic research between W. villosa and other species within Zingiberaceae.

Project description:Apiospora, an ascomycetous genus in Apiosporaceae, comprises saprobes, endophytes, and pathogens of humans and plants. They have a cosmopolitan distribution with a wide range of hosts reported from Asia. In the present study, we collected and isolated Apiospora species from Wurfbainia villosa and grasses in Guangdong and Yunnan provinces in China. Multi-locus phylogeny based on the internal transcribed spacer, the large subunit nuclear rDNA, the partial translation elongation factor 1-α, and β-tubulin was performed to clarify the phylogenetic affinities of the Apiospora species. Based on the distinctive morphological characteristics and molecular evidence, Ap. endophytica, Ap. guangdongensis, Ap. wurfbainiae, and Ap. yunnanensis are proposed. Descriptions, illustrations, and notes for the newly discovered species are provided and compared with closely related Apiospora species. An updated phylogeny of Apiospora is presented, along with a discussion on the phylogenetic affinities of ambiguous taxa.

Project description:Bornyl acetate (BA) is known as a natural aromatic monoterpene ester with a wide range of pharmacological and biological activities. Borneol acetyltransferase (BAT), catalyzing borneol and acetyl-CoA to synthesize BA, is alcohol acetyltransferase, which belongs to the BAHD super acyltransferase family, however, BAT, responsible for the biosynthesis of BA, has not yet been characterized. The seeds of Wurfbainia villosa (homotypic synonym: Amomum villosum) are rich in BA. Here we identified 64 members of the BAHD gene family from the genome of W. villosa using both PF02458 (transferase) and PF07247 (AATase) as Hidden Markov Model (HMM) to screen the BAHD genes. A total of sixty-four WvBAHDs are distributed on 14 chromosomes and nine unanchored contigs, clustering into six clades; three WvBAHDs with PF07247 have formed a separated and novel clade: clade VI. Twelve candidate genes belonging to clade I-a, I-b, and VI were selected to clone and characterize in vitro, among which eight genes have been identified to encode BATs acetylating at least one type of borneol to synthesize BA. All eight WvBATs can utilize (-)-borneol as substrates, but only five WvBATs can catalyze (+)-borneol, which is the endogenous borneol substrate in the seeds of W. villosa; WvBAT3 and WvBAT4 present the better catalytic efficiency on (+)-borneol than the others. The temporal and spatial expression patterns of WvBATs indicate that WvBAT3 and WvBAT4 are seed-specific expression genes, and their expression levels are correlated with the accumulation of BA, suggesting WvBAT3 and WvBAT4 might be the two key BATs for BA synthesis in the seeds of W. villosa. This is the first report on BAT responsible for the last biosynthetic step of BA, which will contribute to further studies on BA biosynthesis and metabolism engineering of BA in other plants or heterologous hosts.
