Abstract ：
Gibberellin (GA) is essential for regulating seed germination, plant growth, flowering, and fruiting. While bamboo, renowned for its rapid growth, relies on GA to promote growth and development, the underlying mechanisms-particularly epigenetic regulations such as N6-methyladenosine (m6A) modification and poly(A) tail length (PAL)-remain poorly understood. In this study, Nanopore direct RNA sequencing (DRS) was utilized to reveal the regulatory effects of GA on m6A modification and PAL in Moso bamboo. These findings highlight the crucial function of m6A modifications and PAL in the growth of Moso bamboo. Specifically, epigenetic modifications of genes participating in GA biosynthesis and metabolism, auxin transport, and abscisic acid signaling contributes to creating a complex hormonal interplay that drives bamboo growth.

Abstract ：
Abscisic acid (ABA) mediates stress responses and growth regulation in plants, but the roles of ABA-responsive transcription factors (TFs) in Populus development remain poorly characterized. Here, we identified an ABA-upregulated TF and investigated its function through overexpression in transgenic poplar. The PtrMYBH is upregulated during ABA treatment, and its overexpression in transgenic poplar leads to leaf malformations, including reduced size and curling, with severity correlating with PtrMYBH-overexpression levels in three independent transgenic lines. PtrMYBH regulates stomatal growth and development, resulting in decreased stomatal length and aperture, along with distinct leaf structural abnormalities. Additionally, PtrMYBH affects root development, with overexpressing lines showing an increase in adventitious root number but shorter lengths, alongside morphological changes in the root elongation zone. Furthermore, morphological changes are observed in the shoot apical meristem (SAM) and stem-differentiating xylem (SDX) of PtrMYBH-overexpressing poplar. RNA-seq analyses reveal PtrMYBH's influence on the expression of genes related to cellular proliferation in the SAM and developmental pathways in the SDX. Finally, in PtrMYBH-overexpressing lines, ABA treatment results in leaf tip damage, earlier leaf drop, and stunted growth, highlighting its critical role in the ABA response. These findings lay a foundation for further exploration of TFs like PtrMYBH to regulate growth in Populus species.

Abstract ：
As the most prevalent RNA modification in eukaryotes, N-6-methyladenosine (m(6)A) plays a crucial role in regulating various biological processes in plants, including embryonic development and flowering. However, the function of m(6)A RNA methyltransferase in moso bamboo remains poorly understood. In this study, we identified two m(6)A methyltransferases in moso bamboo, PheMTA1 and PheMTA2. Overexpression of PheMTA1 and PheMTA2 significantly promoted root development and enhanced salt tolerance in rice. Using the HyperTRIBE method, we fused PheMTA1 and PheMTA2 with ADARcd(E488Q) and introduced them into rice. RNA sequencing (RNA-seq) of the overexpressing rice identified the target RNAs bound by PheMTA1 and PheMTA2. PheMTA1 and PheMTA2 bind to OsATM3 and OsSF3B1, which were involved in the development of root and salt resistance. Finally, we revealed the effects of transcription or alternative splicing on resistance-related genes like OsRS33, OsPRR73, OsAPX2 and OsHAP2E, which are associated with the observed phenotype. In conclusion, our study demonstrates that the m(6)A methyltransferases PheMTA1 and PheMTA2 from moso bamboo are involved in root development and enhance plant resistance to salt stress.

Abstract ：
RNA demethylation plays an important role in diverse biological processes. Intriguingly, RNA demethylation has not been reported in bamboo, which is known for its rapid growth. PheALKBH9, an m6A demethylase in bamboo, was stably transformed into rice and increased its susceptibility to rice blast disease. Heterologous expression of PheALKBH9 reduced the overall m6A modification levels in rice. Using HyperTRIBE (Targets of RNA-binding proteins Identified By Editing), we identified evolutionarily conserved PheALKBH9 target RNAs in both rice and Moso bamboo. Overexpression of PheALKBH9 led to higher protein expression and shorter poly(A) tails. Notably, PheALKBH9 directly bound to CCR4-associated factor1 (CAF1G) and poly(A)-binding genes (PABPC1 and PABPC2), potentially modulating poly(A) tail lengths. In addition, PheALKBH9 also bound to and removed m6A modifications from Perox4, JAZ7, and METS2, key players in plant immunity, suggesting that PheALKBH9 plays a role in plant disease resistance. In summary, our study unveils a previously unknown role of PheALKBH9-mediated m6A demethylation in response to blast disease and provides insights into its mechanisms in monocotyledonous plants. PheALKBH9, an m6A demethylase from Moso bamboo, regulates plant responses to biotic and abiotic stresses by modulating m6A on target RNAs and shortening poly(A) tails.

Abstract ：
The economically important bamboo species Dendrocalamus latiflorus Munro (D. latiflorus) exhibits highly susceptible to Bamboo mosaic virus (BaMV), resulting in severe growth and development impairment. However, the proteomic profiles, transcript processing dynamics, and their coordinated posttranscriptional regulation during bamboo-virus interactions remain uncharacterized. Tandem mass tag (TMT)-based quantitative proteomic revealed suppression of photosynthesis-related proteins and upregulation of protein synthesis and degradation, antioxidant within D. latiflorus during BaMV infection. Moreover, the APR1 protein serviced as a regulatory hub for connecting sulfur metabolism, antioxidant, and photosynthesis. Integration of nanopore direct RNA sequencing (DRS) data revealed reduced D. latiflorus full-length read ratios, consequently attenuating transcriptome and proteome correlation. BaMV-infected bamboos presented preferential usage of distal poly(A) site and lengthened poly(A) tail lengths (PALs) of pathogenesis-related (PR) genes. Epitranscriptome analysis showed increased N6-methyladenosine (m6A) ratios in POR (chlorophyll synthesis) and NCED1 (abscisic acid synthesis), which coupled with reduced transcriptional levels. In total, 122 potential m6A modification sites were found in BaMV, with AAACA representing the predominant consensus motif. Collectively, these results offer insights into posttranscriptional regulation networks during bamboo-BaMV interactions.

Abstract ：
Dendrocalamus brandisii (Munro) Kurz is a sympodial bamboo species with inimitable taste and flavorful shoots. Its rapid growth and use as high-quality material make this bamboo species highly valued for both food processing and wood applications. However, genome information for D. brandisii is lacking, primarily due to its polyploidy and large genome size. Here, we assembled a high-quality genome for hexaploid D. brandisii, which comprises 70 chromosomes with a total size of 2,756 Mb, using long-read HiFi sequencing. Furthermore, we accurately separated the genome into its three constituent subgenomes. We used Oxford Nanopore Technologies long reads to construct a transcriptomic dataset covering 15 tissues for gene annotation to complement our genome assembly, revealing differential gene expression and post-transcriptional regulation. By integrating metabolome analysis, we unveiled that well-balanced lignin formation, as well as abundant flavonoid and fructose contents, contribute to the superior quality of D. brandisii shoots. Integrating genomic, transcriptomic, and metabolomic datasets provided a solid foundation for enhancing bamboo shoot quality and developing efficient gene-editing techniques. This study should facilitate research on D. brandisii and enhance its use as a food source and wood material by providing crucial genomic resources.

Abstract ：
Bamboo is one of the most important nontimber forestry products in the world. Light is not only the most critical source of energy for plant photosynthesis but also involved in regulating the biological processes of plants. However, there are few reports on how blue/red light affects Moso bamboo. This study investigated the growth status and physiological responses of Moso bamboo (Phyllostachys edulis) to blue/red light treatments. The growth status of the bamboo plants was evaluated, revealing that both blue- and red-light treatments promoted plant height and overall growth. Gas exchange parameters, chlorophyll fluorescence, and enzyme activity were measured to assess the photosystem response of Moso bamboo to light treatments. Additionally, the blue light treatment led to a higher chlorophyll content and enzyme activities compared to the red light treatment. A tandem mass tag quantitative proteomics approach identified significant changes in protein abundance under different light conditions with specific response proteins associated with distinct pathways, such as photosynthesis and starch metabolism. Overall, this study provides valuable insights into the physiological and proteomic responses of Moso bamboo to blue/red light treatments, highlighting their potential impact on growth and development.
