AI Article Synopsis
- Bamboo plants are significant for reducing CO2 levels due to their rich PhytOC (phytolith-occluded carbon) content, and this study aimed to improve estimation methods for PhytOC stock in monopodial bamboo species.
- Differences in phytolith and PhytOC content were observed across various parts of the bamboo, with leaves having the highest concentrations compared to branches and culms.
- The findings suggest that to accurately estimate bamboo's PhytOC capacity, researchers should focus on the entire aboveground biomass rather than just individual parts like leaves or litter.
Article Abstract
Bamboo plants have been proven to be rich in phytolith-occluded carbon (PhytOC) and play an important role in reducing atmospheric concentrations of CO2. The object of this paper was to obtain more accurate methods for estimation of PhytOC stock in monopodial bamboo because previous studies may have underestimated it. Eight monopodial bamboo species, widely distributed across China, were selected and sampled for this study in their own typical distribution areas. There were differences (P < 0.05) both in phytolith content (Phytolith/dry biomass) across leaves, branches and culm, and in PhytOC content (PhytOC/dry biomass) across leaves and branches between species, with a trend of leaf > branch > culm. The average PhytOC stored in aboveground biomass and PhytOC production flux contributed by aboveground biomass varied substantially, and they were 3.28 and 1.57 times corresponding dates in leaves, with the highest in Phyllostachys glauca McClure and lowest in Indocalamus tessellatus (Munro) Keng f. It can be concluded that it could be more accurate to estimate PhytOC stock or PhytOC production flux by basing on whole aboveground biomass rather than on leaf or leaf litter only. The whole biomass should be collected for more estimation of bamboo PhytOC sequestration capacity in the future.

Fungal endophytes in plant leaf mesophyll form mutually beneficial associations through carbon assimilation, synthesis of biologically active chemicals, and enhancement of aesthetic and nutritional value. Here, we compared community structure, diversity, and richness of endophytic fungi in the leaves of three bamboo species, including Phyllostachys edulis (MZ), Bambusa rigida (KZ), and Pleioblastus amarus (YT) via high-throughput Illumina sequencing. In total, 1070 operational taxonomic units (OTUs) were retrieved and classified into 7 phylum, 27 classes, 82 orders, 185 families, 310 genus, and 448 species.

Moso bamboo (Phyllostachys edulis), typically a monopodial scattering bamboo, is famous for its rapid growth. The rhizome-root system of Moso bamboo plays a crucial role in its clonal growth and spatial distribution. However, few studies have focused on rhizome-root systems.

Bamboo is one of the fastest growing plants among monocotyledonous species and is grown extensively in subtropical regions. Although bamboo has high economic value and produces much biomass quickly, gene functional research is hindered by the low efficiency of genetic transformation in this species. We therefore explored the potential of a bamboo mosaic virus (BaMV)-mediated expression system to investigate genotype-phenotype associations.

Moso bamboo () is the most important monopodial bamboo species worldwide. Without a genetic transformation system, it is difficult to verify the functions of genes controlling important traits and conduct molecular breeding in moso bamboo. Here, we established a plant regeneration system from immature embryos.

Article Synopsis
- The study examined the effects of watching videos of bamboo forests on 180 Chinese university students, measuring their physiological (like EEG, blood pressure, and pulse) and psychological responses (mood changes).
- Physiological indicators showed notable changes within the first minute of viewing, with EEG levels stabilizing, blood pressure significantly dropping after 3 minutes, and skin conductance increasing consistently throughout the viewing period.
- The type of bamboo forest influenced the results, with sympodial bamboo reducing tension more effectively and higher canopy density forests leading to lower alpha waves, indicating a more relaxed state for the viewers.
