This study reveals miRNA indirect regulation of C genes in sugarcane through transcription factors, highlighting potential key regulators like SsHAM3a. C photosynthesis is crucial for the high productivity and biomass of sugarcane, however, the miRNA regulation of C genes in sugarcane remains elusive. We have identified 384 miRNAs along the leaf gradients, including 293 known miRNAs and 91 novel miRNAs.

Homeobox (HB) genes play important roles in plant growth and development processes, particularly in the formation of lateral organs. Thus, they could influence leaf morphogenesis and biomass formation in plants. However, little is known about in sugarcane, a crucial sugar crop, due to its complex genetic background.

We have assembled a high-quality autopolyploid genome of S. spontaneum Np-X (2n = 4x = 40) into 40 pseudochromosomes across 10 homologous groups, that better elucidates recent chromosome reduction and polyploidization that occurred circa 1.

Article Synopsis
- The mating compatibility of the edible mushroom Hypsizygus marmoreus is controlled by two unlinked mating type loci (MAT) with a tetrapolar system, which includes HD transcription factor genes and pheromone-related genes.
- DNA sequencing of various strains revealed that while the gene order in HD loci is conserved, the gene content can vary, resulting in four distinct haplotype types that are heritable and closely linked.
- Phylogenetic analysis of pheromone receptors suggests that they split into three groups before the species diverged and highlights the diversity in MAT regions among different fungi, which may enhance mating compatibility.
Hypsizygus marmoreus is one of the most important edible fungi in Basidiomycete division and includes white and gray strains. However, very limited knowledge is known about the genomic structures and the genetic basis for the white/gray diversity of this mushroom. Here, we report the near-complete high-quality H.

Article Synopsis
- A high-quality genome of goldfish has been sequenced, revealing its structure of 50 pseudochromosomes and the impact of over 1,000 years of domestication through selective breeding.* -
- The study identified two subgenomes from an ancient hybridization and correlated genetic variations with specific anatomical features of goldfish varieties, including differences among traditional clades.* -
- A candidate gene linked to the transparent mutant phenotype was discovered, positioning goldfish as a valuable model for researching functional genomics and the effects of domestication.*

Background: Hypsizygus marmoreus, a high value commercialized edible mushroom is widely cultivated in East Asia, and has become one of the most popular edible mushrooms because of its rich nutritional and medicinal value. Mitochondria are vital organelles, and play various essential roles in eukaryotic cells.
Results: In this study, we provide the Hypsizygus marmoreus mitochondrial (mt) genome assembly: the circular sequence is 102,752 bp in size and contains 15 putative protein-coding genes, 2 ribosomal RNAs subunits and 28 tRNAs.
