ABSTRACT
Pleurotus citrinopileatus is a low-cholesterol, protein-rich, and high-nutrient food. The molecular mechanisms of the compounds and coloration have not been reported. Metabolome and transcriptome were used to clarify the molecular mechanisms of key compounds biosynthesis. K-means analysis identified 19 compounds in P. citrinopileatus, mainly lipids and alkaloids in class 8. In addition, 84 lipids were higher and that the different compounds were mainly enriched in linoleic acid metabolism. A total of 14 compounds detected in the linoleic acid metabolism pathway were significantly up-regulated, while 3 sterol regulatory element binding protein (SREBP) transcription factors were screened. Tryptophan metabolism and riboflavin biosynthesis pathway analysis indicated that 3 Unigenes had tryptophan decarboxylase similar elements, which belonged to tyrosine decarboxylase 1. Moreover, CL15618.Contig5_All had high homology with MFS. In conclusion, the expression of 3 SREBP, the synthesis of isobavachalcone D, and the regulation of riboflavin transport by MCH5 were the reasons for fatty acid accumulation and yellow cap formation in the P. citrinopileatus.

Allium mongolicum is a kind of wild vegetable with high nutritional value and even a traditional Chinese medicine. Here, we reported the complete chloroplast genome sequence of Allium mongolicum. The size of the chloroplast genome is 153,376 bp in length, including a large single copy region (LSC) of 82,912 bp, a small single copy region (SSC) of 18,054 bp, and a pair of inverted repeated regions of 26,205 bp. The Allium mongolicum chloroplast genome encodes 115 genes, including 69 protein-coding genes, 38 tRNA genes, and eight rRNA genes. Phylogenetic tree showed that Allium mongolicum is closely related to Allium przewalskianum.
ABSTRACT
Allium tuberosum is a popular vegetable, condiment, and even a traditional Chinese medicine. Here, the complete chloroplast genome sequence of Allium tuberosum was reported. The size of the chloroplast genome is 154,056 bp in length, including a large single copy region (LSC) of 83,068 bp, a small single copy region (SSC) of 17,958 bp, and a pair of inverted repeat (IR) regions with 26,515 bp. The Allium tuberosum chloroplast genome encodes 132 genes, including 87 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Phylogenetic tree analysis suggested that Allium tuberosum was closely related to Allium sativum.
