Alpinia oxyphylla Miq . ( A . oxyphylla ) is an important edible and traditional herbal medicine. In this study, the complete chloroplast genome of A . oxyphylla was sequenced, analysed, and compared to five species in the Zingiberaceae family. The size of the A . oxyphylla chloroplast genome was 161351 bp, which consisted of a large single-copy (LSC, 87248 bp) and small single-copy (SSC, 16175 bp) region separated by a pair of inverted repeats (IRa and IRb, 28964 bp each). The genome encoded 132 unique genes, including 87 protein-coding genes, 37 tRNAs and four rRNAs. The GC content of the genome was 36.17%. A total of 53 simple sequence repeats (SSRs) and 80 long repeats were identified in the A . oxyphylla chloroplast genome. The chloroplast genome of A . oxyphylla shared the highest sequence similarity of >90% with the chloroplast genome of A . zerumbet , and six chloroplast genomes in the Zingiberaceae family were compared by using CGView Comparison Tool (CCT). According to the phylogenetic tree, the Zingiberaceae family is divided into two categories, which coincide with the classification of the characteristics of sun-like and shade-like in plants. Our results reveal the phototrophic component of NADH-dehydrogenase (ndhB and ndhC), photosystem II (psbZ) and ATP synthase (atpE, atpF) exhibit adaptive evolution under different environments, and the strength of light is an important trigger for the adaptations at the chloroplast level.

“…Until now, research on H. borneense is limited. Several studies have been conducted, including those on morphology and anatomy (Benedict 2012, Gevu et al 2017, propagation (Trimanto et al 2019), and DNA- (Wood et al 2000, Lin-Chun et al 2011, and even then, not specific to H. borneense. The IUCN (2019) redlist notes that H. borneense's status is Data Deficient, implying insufficient knowledge and data to estimate the risk of extinction based on population status and distribution.…”

Morphological, phenological characterization and conservation management of Hedychium borneense R.M.Sm, a terrestrial-epiphytic herb and endemic to Kalimantan, Borneo are described. Results revealed that H. bornensee has a purple-brownish bractea, a terminal and raceme inflorescence, pale yellow flowers with a broad and pale-yellow labellum and orange stamen, a triocular fruit with an orange to red inner color, and brownish seeds with a dark red arillus. There are six phenology phases: initiation phase, flower development phase, pre-anthesis phase, anthesis phase, post-anthesis phase, and fruit development. Flower development lasts for 34 days, with a two-day anthesis phase in between. The ripe fruit occurs on day 94. It grows best in porous, moist environment; sphagnum moss and sand mix compost (1:1) is the best media for this plant. Since the plant is endemic, ex-situ conservation management through generative propagation is observed to be essential. Bangladesh J. Bot. 51(2): 313-323, 2022 (June)

“…Most of the microfibrils are radially arranged, while some are arranged in a tangential or oblique direction. The sap flow between adjacent tracheids (Figure 1d,e) in coniferous wood xylem is mainly realized by the pores on the margo [4,5]. These pores enable the liquid to pass through the tracheids in a flexible manner, which is essential for preventing the spread of viral pathogens in tracheids and for preventing embolism in the whole xylem as well as for promoting tree growth [6,7].…”

Fluid flow between adjacent tracheids is realized through bordered pits in the xylem of conifers. The pit has an extremely small size and a highly complex structure. This paper presents a mesoscopic analytical method for the relationship between the pit structure and its hydraulic characteristics through mathematical modeling using the lattice Boltzmann method (LBM) and curved boundary treatment. Mongolian Scots pine were selected as the research subject of this study, and the bordered pit structure parameters was collected by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and the original geometric features were maintained for direct modeling analysis. The model revealed the relationship between various components of the bordered pit and liquid flow velocity/resistance, indicating that margo is the main factor affecting flow resistance. Further anatomical investigation separately analyzed the influence of change in a single factor, including pit diameter, pit aperture diameter, pit depth, torus diameter, and margo thickness, on the overall flow and pressure drop to confirm the importance of various factors in this relationship. Additionally, the influence of pore size and pore location distribution in the margo on the flow rate and pressure drop was further analyzed quantitatively. The results showed that the flow rate through individual pores is the result of the combined effect of pore area and radial position of the pore in the margo. Our study promotes the research and application of the mesoscopic model LBM in simulating flow conditions in the complex flow field of pits, which realizes the numerical analysis of the flow field model based on individualized real bordered pits. In comparison with the classical macroscopic model, the accuracy and effectiveness of the proposed model are proved. This research can provide a promising method for analyzing the physiological and ecological functions of conifer and realizing the efficient utilization of wood resources.
