Keyword phrases: Naematelia aurantialba; whole-genome sequencing; functional annotation; secondary metabolism; polysaccharides1. Introduction Mushrooms are widely distributed food and medicine resource on Earth and have great nutritional and medicinal worth [1,2]. The mushrooms are thought of as superfoods, which are amongst the world’s healthiest foods, and around 50 of edible mushrooms are recognized as functional foods [3]. Naematelia aurantialba syn. Tremella aurantialba, also called Jin’er, an edible and medicinal fungus distributed in China, is extensively common for the reason that of its unique flavor and higher nutritional worth in its fruiting bodies [4]. Prior studies have reported that the primary medicinal functions of N. aurantialba incorporate antioxidant, anti-inflammatory, anti-tumor, and immunomodulatory effects, for which polysaccharides, active proteins, and terpenoids are responsible [5]. Polysaccharides are recognized as one of probably the most active compounds in N. aurantialba, which includes a total carbohydrate content of 74.11 , including a 40 content of ADAM17 MedChemExpress water-soluble polysaccharides [7]. Furthermore, N. aurantialba is actually a fungus containing phenolic acids and flavonoids, which has antioxidant effects [10]. The fruiting body of N. aurantialba grows on rotten wood, which has the potential to degrade lignocellulose since it is actually wealthy in carbohydrate-active enzymes (CAZymes) [11,12]. It truly is also achievable that N. aurantialba has these degradingCopyright: 2021 by the authors. Licensee MDPI, Basel, Switzerland.

With the speedy improvement of DNA sequencing technology and gene-editing technology, strengthening the polysaccharide synthetic pathway by means of metabolic engineering approaches has become a attainable solution to improve the yield of mushroom polysaccharides, which can lead to the industrial production of polysaccharides in the future [136]. Nevertheless, there happen to be no reports on improving the production of N. aurantialba polysaccharides by genetic modification techniques. The reason is mainly due to the lack of relevant genome-wide information and facts, which limits the development of genetic manipulation approaches. Also, the development of genome sequencing technologies has provided new insights into active compound mining, wide variety breeding, high-yield cultivation, and population genetics [171]. The taxonomic boundaries among mushrooms are blurred, and fungal names have extended been controversial, which has led to slow improvement of fantastic excellent PAR2 review varieties of mushrooms and hence issues in reaching large-scale production [22]. The medicinally valuable sang’huang recorded within the ancient book of conventional Chinese medicine has previously been viewed as as Sanghuangporus baumii and Sanghuangporus vaninii; but, Ying et al. clarified its taxonomic status by comparative genomic evaluation and named it sanghuangporus sangguang [22,23]. The golden needling mushroom in East Asia has been reported as Asian Flammulina velutipes or Flammulina velutipes var. filiformis [24]. Even so, the phylogenetic results.
