Abstract
Woody bamboo exhibits a unique flowering characteristic with a lengthy flowering cycle, often followed by death. In many plant species, alternative splicing (AS) is a common phenomenon involved in controlling flowering. In this study, a PeCOL13 gene in moso bamboo (Phyllostachys edulis) was characterized. It produced two isoforms: PeCOL13α and PeCOL13β, due to an intron-retained AS. The PeCOL13α expressed in the vegetative phase and the reproductive phase, but the PeCOL13β didn't express during the vegetative phase and showed only a weak expression from F1 to F3 during the reproductive phase. Overexpression of PeCOL13α in rice (Oryza sativa) resulted in a delayed heading time through inhibiting the expressions of Hd3a, OsFTL1, and Ehd1 and activating the expressions of Ghd7 and RCN1. However, the PeCOL13β-overexpressed rice didn't show any significant differences in flowering compared with wild-type (WT), and the expressions of downstream flowering genes had no notable changes. Further analysis revealed that both PeCOL13α and PeCOL13β can bind to the PeFT promoter. Meanwhile, PeCOL13α can inhibit the transcription of PeFT, but PeCOL13β showed no effect. When PeCOL13α and PeCOL13β coexist, the inhibitory effect of PeCOL13α on PeFT transcription was weakened by PeCOL13β. This study provides new insights into the mechanism of bamboo flowering research.

Nat Commun 2024; 15:3305. [PMID: 38632270 PMCID: PMC11024178 DOI: 10.1038/s41467-024-47428-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 04/02/2024] [Indexed: 04/19/2024] Open
Abstract
Poaceae members shared a whole-genome duplication called rho. However, little is known about the evolutionary pattern of the rho-derived duplicates among Poaceae lineages and implications in adaptive evolution. Here we present phylogenomic/phylotranscriptomic analyses of 363 grasses covering all 12 subfamilies and report nine previously unknown whole-genome duplications. Furthermore, duplications from a single whole-genome duplication were mapped to multiple nodes on the species phylogeny; a whole-genome duplication was likely shared by woody bamboos with possible gene flow from herbaceous bamboos; and recent paralogues of a tetraploid Oryza are implicated in tolerance of seawater submergence. Moreover, rho duplicates showing differential retention among subfamilies include those with functions in environmental adaptations or morphogenesis, including ACOT for aquatic environments (Oryzoideae), CK2β for cold responses (Pooideae), SPIRAL1 for rapid cell elongation (Bambusoideae), and PAI1 for drought/cold responses (Panicoideae). This study presents a Poaceae whole-genome duplication profile with evidence for multiple evolutionary mechanisms that contribute to gene retention and losses.

Abstract
Bamboo is a highly renewable biomass resource with outstanding ecological, economic and social benefits. However, its lengthy vegetative growth stage and uncertain flowering period have hindered the application of traditional breeding methods. In recent years, significant progress has been made in bamboo breeding. While technical advances in bamboo breeding have been impressive, it is essential to also consider the broader implications we can learn from bamboo's extraordinary features for sustainable development. This review provides an overview of the current status of bamboo breeding technology, including a detailed history of bamboo breeding divided into four eras, a comprehensive map of bamboo germplasm gardens worldwide, with a focus on China, and a summary of available transgenic technologies for gene function verification and genetic improvement. As the demand for bamboo as a sustainable and renewable resource increases continuously, breeding objectives should be focused on enhancing yield, wood properties and adaptability to diverse environmental conditions. In particular, priority should be given to improving fiber length, internode length and wall thickness, as well as regulating lignin and cellulose content for papermaking, substitute for plastic and other applications. Furthermore, we highlight the challenges and opportunities for future research and development in bamboo breeding, including the application of omics technologies, artificial intelligence and the development of new breeding methods. Finally, by integrating the technical advances in bamboo breeding with a discussion of its broader implications for sustainable development, this review provides a comprehensive framework for the development of bamboo industry.

Abstract
Mucor racemosus is the predominant fungal in the zhiqu stage of the fermentation of Yongchuan Douchi (Mucor-type), which plays an important role in the fermentation process of Yongchuan Douchi. However, there is a lack of information on the genetic analysis of M. racemosus. In this study, we isolated and identified M. racemosus C (accession no JAPEHQ000000000) from Yongchuan Douchi and analyzed the physiological indicators, then genomic information of the strain to perform a comprehensive analysis of its fermentation capacity and safety. M. racemosus C had neutral protease activity up to 68.051 U/mL at 30 °C and alkaline protease activity up to 57.367 U/mL at 25 °C. In addition, comparing the genomic data with the COGs database (NCBI), it was predicted that M. racemosus C undergoes extensive amino acid metabolism, making C suitable for the production of fermented foods (e.g., Douchi, Syoyu, and sufu). Finally, we performed virulence genes and resistance genes analysis, hemolysis experiment, aflatoxins assay, antibiotic resistance assay to evaluate the safety of M. racemosus C, and the results showed that M. racemosus C was safe, non-toxin-producing and non-hemolytic.

Abstract
As drivers of evolutionary innovations, new genes allow organisms to explore new niches. However, clear examples of this process remain scarce. Bamboos, the unique grass lineage diversifying into the forest, have evolved with a key innovation of fast growth of woody stem, reaching up to 1 m/day. Here, we identify 1,622 bamboo-specific orphan genes that appeared in recent 46 million years, and 19 of them evolved from noncoding ancestral sequences with entire de novo origination process reconstructed. The new genes evolved gradually in exon−intron structure, protein length, expression specificity, and evolutionary constraint. These new genes, whether or not from de novo origination, are dominantly expressed in the rapidly developing shoots, and make transcriptomes of shoots the youngest among various bamboo tissues, rather than reproductive tissue in other plants. Additionally, the particularity of bamboo shoots has also been shaped by recent whole-genome duplicates (WGDs), which evolved divergent expression patterns from ancestral states. New genes and WGDs have been evolutionarily recruited into coexpression networks to underline fast-growing trait of bamboo shoot. Our study highlights the importance of interactions between new genes and genome duplicates in generating morphological innovation.

Abstract
Bamboos represent an emerging forest resource of economic significance and provide an avenue for sustainable development of forest resources. The development of the commercial bamboo industry is founded upon efficient molecular and technical approaches for the selection and rapid multiplication of elite germplasm for its subsequent propagation via commercial agro-forestry business enterprises. This review will delve into the micropropagation of Dendrocalamus asper, one of the most widely cultivated commercial varieties of bamboo, and will encompass the selection of germplasm, establishment of explants in vitro and micropropagation techniques. The currently available information pertaining to molecular biology, DNA barcoding and breeding, has been included, and potential areas for future research in the area of genetic engineering and gene regulation have been highlighted. This information will be of relevance to both commercial breeders and molecular biologists who have an interest in establishing bamboo as a crop of the future.
