MYCOBIOLOGY 2018; 46:72-78. [PMID: 29998035 PMCID: PMC6037080 DOI: 10.1080/12298093.2018.1454004] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/17/2017] [Revised: 01/05/2018] [Accepted: 01/19/2018] [Indexed: 06/08/2023]
Abstract
The fruiting body pattern is an important agronomic trait of the edible fungus Auricularia auricula-judae, and an important breeding target. There are two types of fruiting body pattern: the cluster type and the chrysanthemum type. We identified the fruiting body pattern of 26 test strains, and then constructed two different near-isogenic pools. Then, we developed sequence characterized amplified region (SCAR) molecular markers associated with the fruiting body pattern based on sequence-related amplified polymorphism (SRAP) markers. Ten different bands (189-522 bp) were amplified using 153 pairs of SRAP primers. The SCAR marker "SCL-18" consisted of a single 522-bp band amplified from the cluster-type strains, but not the chrysanthemum strains. This SCAR marker was closely associated with the cluster-type fruiting body trait of A. auricula-judae. These results lay the foundation for further research to locate and clone genes controlling the fruiting body pattern of A. auricula-judae.

[PMID: 29149037 PMCID: PMC5704238 DOI: 10.3390/genes8110325] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Revised: 10/16/2017] [Accepted: 11/08/2017] [Indexed: 01/02/2023] Open
Abstract
Identification of monokaryons and their mating types and discrimination of hybrid offspring are key steps for the crossbreeding of Pleurotus tuoliensis (Bailinggu). However, conventional crossbreeding methods are troublesome and time consuming. Using RNA-seq technology, we developed new expressed sequence tag-simple sequence repeat (EST-SSR) markers for Bailinggu to easily and rapidly identify monokaryons and their mating types, genetic diversity and hybrid offspring. We identified 1110 potential EST-based SSR loci from a newly-sequenced Bailinggu transcriptome and then randomly selected 100 EST-SSRs for further validation. Results showed that 39, 43 and 34 novel EST-SSR markers successfully identified monokaryons from their parent dikaryons, differentiated two different mating types and discriminated F1 and F2 hybrid offspring, respectively. Furthermore, a total of 86 alleles were detected in 37 monokaryons using 18 highly informative EST-SSRs. The observed number of alleles per locus ranged from three to seven. Cluster analysis revealed that these monokaryons have a relatively high level of genetic diversity. Transfer rates of the EST-SSRs in the monokaryons of closely-related species Pleurotuseryngii var. ferulae and Pleurotus ostreatus were 72% and 64%, respectively. Therefore, our study provides new SSR markers and an efficient method to enhance the crossbreeding of Bailinggu and closely-related species.

Abstract
Lepista nuda (Bull. ex Fr.) Cooke (Tricholomataceae) is an edible fungus with both economic and medical value. Identification of its mating-type loci is important for promoting breeding programs in L. nuda. The A mating-type locus of L. nuda and its flanking region were cloned and characterized in the present study. It contained two homeodomain transcription factor genes (called lna1 and lna2). Lna1 and Lna2 protein harbored conserved motif of homeodomain transcription factor protein. The novel finding of this study was that the gene order around the A locus was mip, lna2, lna1, and β-fg in L. nuda, which was differed from other edible fungi. In addition, lna1 and lna2 showed divergent, inward transcriptional direction. The phylogenetic tree of HD proteins showed that L. nuda Lna1 and Lna2 were phylogenetically related with Laccaria bicolor. Our results revealed that the A mating-type locus had been subjected to gene rearrangements relative to all other basidiomycetes.
