“…Hundreds of woody bamboo species occur on the red soil and are characterized by their rapid growth [30]. Previous studies showed significant upregulation of genes associated with cell elongation or division, hormone signal transduction and cell wall development during the rapid growth period of woody bamboo [26,31,59]. However, there were few studies on the relationship between red soil micro-organisms and rapid growth of woody bamboos.…”

“…Considering that woody bamboos are of crucial economic, ecological and cultural value in their distribution area [24], the introduction and cultivation of excellent bamboo resources have attracted increasing interest in both academia and industry in recent years [25]. The rapid growth of young culms is one of the most striking biological features of woody bamboos [26,27]. Due to low contents of organic carbon and soil nutrient in acidic red soil [1], rapidly growing bamboo plants may be more susceptible to the influence of rhizosphere micro-organisms on their nutrient absorption [11].…”

“…However, the narrow natural distribution of D. sinicus poses a limitation to its cultivation and utilization [25]. In the previous studies, we investigated its biological characteristics, including the mating system [32] and culm development [26,31]. Furthermore, our study investigated the impact of climate factors on the distribution of D. sinicus, revealing a substantially broader potential distribution range compared to its current range [25].…”

The interaction between soil microbes and plants has a significant effect on soil microbial structure and function, as well as plant adaptability. However, the effect of soil micro-organisms on ecological adaption and rapid growth of woody bamboos remains unclear. Here, 16S rRNA and ITS rRNA genes of rhizosphere micro-organisms were sequenced, and the soil properties of three different types of Dendrocalamus sinicus were determined at the dormancy and germination stages of rhizome buds. The result showed that each type of D. sinicus preferred to absorb ammonia nitrogen (NH4+-N) rather than nitrate nitrogen (NO3−-N) and required more NH4+-N at germination or rapid growth period than during the dormancy period. In total, nitrogen fixation capacity of soil bacteria in the straight type was significantly higher than that in the introduced straight type, while the ureolysis capacity had an opposite trend. Saprophytic fungi were the dominant fungal functional taxa in habitat soils of both straight and introduced straight type. Our findings are of great significance in understanding how soil microbes affect growth and adaptation of woody bamboos, but also for soil management of bamboo forests in red soil.

“…High-throughput RNA sequencing (RNA-seq) has been recognized as one of the widespread tools for measuring gene transcriptional expression profiles, and it can provide a superior platform for a comprehensive understanding of the contribution of TFs to plant regulatory systems [26,27]. To date, studies on the transcriptional regulation of genes against saline stress in polyploid rice are limited.…”

Saline stress is a major abiotic stress that inhibits plant growth and yields worldwide. The plant transcription factor (TF) family plays an important role in converting abiotic stress signals into gene expression changes. In this study, a transcriptome-based comparative analysis was performed to investigate the global gene expression of all the TFs in diploid and autotetraploid rice during the early stage of NaCl stress and recovery period. The phenotypic data indicated that the tetraploid rice exhibited a superior salt-tolerant ability compared to the diploid rice. A total of 55 TF families were co-expressed in the tetraploid and diploid rice, and the cumulative number of TF-expressed genes was relatively higher in the diploid rice than in the tetraploid rice at all time points. Unlike the diploid rice, the overall gene expression levels of the tetraploid rice were comparable to the control during recovery. The number of differentially expressed TFs (DE-TFs) in the tetraploid rice decreased after recovery, whereas it increased to a large extent in the diploid rice. GO and KEGG pathway enrichment analysis of the DE-TFs discovered the early switching of the ABA-activated signaling pathway and specific circadian rhythm in the tetraploid rice. Combining the PPI network and heatmap analysis, some core DE-TFs were found that may have potential roles to play in tetraploid salt tolerance. This study will pave the way for elucidating the complex network regulatory mechanisms of salt tolerance in tetraploid rice.
