Physicochemical evaluation, structural characterization, in vitro and in vivo bioactivities of water-soluble polysaccharides from Luobuma (Apocynum L.) tea.

Luobuma tea is made from the leaves of Apocynum hendersonii (Bt) and A. venetum (Ht) and has been used for a very long time in China and Japan as herbal tea. This study isolated water-soluble polysaccharides from the two species` teas.

Comprehensive Analysis of WUSCEL-Related Homeobox Gene Family in Ramie () Indicates Its Potential Role in Adventitious Root Development.

A WUSCHEL-related homeobox (WOX) gene family has been implicated in promoting vegetative organs to embryonic transition and maintaining plant embryonic stem cell identity. Using genome-wide analysis, we identified 17 candidates, WOX genes in ramie (). The genes (BnWOX) showed highly conserved homeodomain regions typical of WOX.

Comparative genome and metabolome analyses uncover the evolution and flavonoid biosynthesis between and .

species have great application prospects in textile and phytoremediation of saline soil, are rich in flavonoids, and possess medicinal significance. Here, we report the draft genomes of and , and elucidate their evolutionary relationship. The high synteny and collinearity between the two suggested that they have experienced the same WGD event.

Genome-Wide Investigation of the NAC Transcription Factor Family in Revealed Their Synergistic Roles in Abiotic Stress Response and Trehalose Metabolism.

NAC (NAM, ATAF1/2, and CUC2) transcription factors (TFs) are one of the most prominent plant-specific TF families and play essential roles in plant growth, development and adaptation to abiotic stress. Although the NAC gene family has been extensively characterized in many species, systematic analysis is still relatively lacking in (). In this study, 74 AvNAC proteins were identified from the genome and were classified into 16 subgroups.

Genome-wide analysis of R2R3-MYB transcription factors in (L.) gaudich revealed potential cadmium tolerance and anthocyanin biosynthesis genes.

Gene family, especially MYB as one of the largest transcription factor family in plants, the study of its subfunctional characteristics is a key step in the study of plant gene function. The sequencing of ramie genome provides a good opportunity to study the organization and evolutionary characters of the ramie MYB gene at the whole genome level. In this study, a total of 105 BnGR2R3-MYB genes were identified from ramie genome and subsequently grouped into 35 subfamilies according to phylogeny divergence and sequences similarity.

Genome-Wide Analysis of AP2/ERF Gene Superfamily in Ramie ( L.) Revealed Their Synergistic Roles in Regulating Abiotic Stress Resistance and Ramet Development.

AP2/ERF transcription factors (TFs) are one of the largest superfamilies in plants, and play vital roles in growth and response to biotic/abiotic stresses. Although the AP2/ERF family has been extensively characterized in many species, very little is known about this family in ramie ( L.).

Total Flavonoids Extracts of L. from the Ili River Valley Region at Different Harvesting Periods and Bioactivity Analysis.

In the current study, the total content from two species leaves ( and ) collected from the Ili River Valley Region were extracted, and their bioactivities were investigated. The results showed a significant variation in the total flavonoid contents in the leaf samples collected at different periods (June, July, August, and September), with the highest content in August (60.11 ± 0.

Phytochemical Composition, Antioxidant, Antibacterial, and Enzyme Inhibitory Activities of Various Organic Extracts from (Hook.f.) Woodson.

a traditional medicinal plant used primarily as tea. It has a potential health benefit from its rich bioactive substances. This study investigated the reactivity of solvents of different polarities (ethanol, ethyl acetate, n-hexane, methanol, and water) extracts of the leaf.

Analysis of WRKY Resistance Gene Family in (L.) Gaudich: Crosstalk Mechanisms of Secondary Cell Wall Thickening and Cadmium Stress.

A total of 60 WRKY family genes of ramie were identified in the ramie. The genes were unevenly distributed across 14 chromosomes in the specie and highly concentrated (72%) in the distal telomeric region. Phylogenetic analysis placed these genes into seven distinct subfamilies groups: I, II (a, b, c, d, e), and III, with group IIc containing only the variant of heptapetide sequence (WRKYGKK).

Genome wide characterization of R2R3 MYB transcription factor from Apocynum venetum revealed potential stress tolerance and flavonoid biosynthesis genes.

MYB transcription factors are crucial in regulating stress tolerance and expression of major genes involved in flavonoid biosynthesis. The functions of MYBs is well explored in a number of plants, yet no study is reported in Apocynum venetum. We identified a total of 163 MYB candidates, that comprised of 101 (61.

Transcriptome and metabolome analysis reveals anthocyanin biosynthesis pathway associated with ramie (Boehmeria nivea (L.) Gaud.) leaf color formation.

Background: The bast fiber crop ramie can be used as high-quality forage resources, especially in tropical or subtropical region where there is lack of high-quality protein feed. Hongxuan No.1 (HX_1) is a unique ramie variety with a light reddish brown leaf color, which is obviously different from elite cultivar, Zhongzhu No.

Genomic Survey, Transcriptome, and Metabolome Analysis of and to Reveal Major Flavonoid Biosynthesis Pathways.

Then, the metabolome and transcriptome analyses were combined to elucidate the flavonoid biosynthesis pathways.

Analysis of BnMTL, a novel metallothionein-like protein in the bast fiber crop Ramie (Boehmeria nivea).

Ramie (Boehmeria nivea) is a perennial herb that is highly tolerant of heavy metals. In the present study, we cloned a novel metallothionein-like gene from ramie; this gene, termed BnMTL, encodes a putative 46 amino acid protein with a molecular mass of 4.38 kDa.
