Lentinula edodes is an important cultivated mushroom in China. The development of Lentinula edodes production promotes more studies on it. In our previous work, degenerate PCR and chromosome walking technologies were used to obtain one pheromone receptor gene and one pheromone precursor gene from Lentinula edodes. In this study, four pairs of specific primers were designed according to the whole genome sequencing of the protoplast monokaryon of Lentinula edodes strain 135, to amplify STE3-like pheromone receptor gene and its flanking conserved genes in the protoplast monokaryon strain SUP2 derived from Lentinula edodes strain Suxiang and 33655bp DNA sequence was obtained. By BlastX search, seven putative genes were identified, and three of them are pheromone receptor encoded genes. Furthermore, near to two pheromone receptor genes, four genes encoding proteins with conserved motifs of pheromone precursors were found. This study firstly reveals the molecular organization of the B mating type locus of Lentinula edodes.

As China has gradually enhanced the levels of economic development and national income or consumption in recent years, to increase the consumption of baby products, markets for high-quality baby products are spotlighted so that the baby product market in China has been growing rapidly and the prospect is bright as well. The government changed the one-child policy into the two-child policy to increase the birth rate from 2015. This policy change can result in the enlargement of the baby goods market. In this regard, this study suggests the following strategies for promoting infant products to China and concrete ways of entering the market. The strategies to enter the Chinese markets are as follows. First, in order to successfully enter China, it is important to understand the situation and characteristics of the Chinese market with Chinese market research and accurate understanding about the recent economic environment in China. Second, enabling online and offline integration and SNS on brand advertisement are necessary. Third, reinforcement of the Wang Hong marketing. Fourth, reinforcement of customer service. Fifth, products promotion through TV advertisement. Sixth, usage of the relationship properly. Seventh, securing the overseas certification system. This study may provide the good implications not only to Korean baby product companies which want to enter the Chinese market but also to the peoples who want to establish the entry strategy into China.
