Summary The capability to maintain cell wall integrity is critical for plants adapt unfavourable conditions. l ‐Arabinose (Ara) a constituent of several polysaccharides and many wall‐localised glycoproteins, but so far the contribution Ara metabolism abiotic stress tolerance still poorly understood. Here, we report that mutations in MUR 4 (also known as HSR 8 ) gene, which required biosynthesis UDP ‐Ara p Arabidopsis, led reduced root elongation under high concentrations NaCl, KC l, Na NO 3...
Four-Coumarate:CoA ligase gene (4CL) plays multiple important roles in plant growth and development by catalyzing the formation of CoA ester. 4CL belongs to phenylpropane derivative, which is related synthesis flavonoids lignin a key enzyme biosynthetic pathway. In this study, 12 genes Fraxinus mandschurica were identified named Fm4CL1-Fm4CL12, respectively. The analysis expression pattern Fm4CL indicate that Fm4CL-like 1 may play role Our study overexpression increases content transgenic...
The basic helix-loop-helix (bHLH) transcription factors (TFs) are involved in plant morphogenesis and various abiotic biotic stress responses. However, further exploration is required of drought-responsive bHLH family members their detailed regulatory mechanisms Populus. Two TF genes, PxbHLH01/02, were identified Populus simonii × P. nigra cloned. aim this study was to examine the role TFs drought tolerance nigra. results showed that amino acid sequences two genes homologous Arabidopsis...
Evidence supporting nitric oxide (NO) as a mediator of plant biochemistry continues to grow, but its functions at the molecular level remains poorly understood and, in some cases, controversial. To study role NO transcriptional Betula platyphylla cells, we conducted genome-scale transcriptome analysis these cells. The untreated birch cells and those treated by sodium nitroprusside (SNP) were analyzed using Solexa sequencing. Data collected sequencing cDNA libraries which had long period...
SQUAMOSA promoter binding protein-like (SPL) is a unique family of transcription factors in plants, which engaged regulating plant growth and development, physiological biochemical processes. Fraxinus mandshurica an excellent timber species with wide range uses northeastern China enjoys high reputation the international market. SPL analysis has been reported some plants while not reported.We used phylogeny, conserved motifs, gene structure, secondary structure prediction, miR156 sites, cis...
The objective of this work was the optimization conditions callus and cell suspension culture Elaeagnus angustifolia for production condensed tannins. effects different on growth tannins were researched. leaf tissue part E. optimum explant induction. best highest obtained under MS basal medium containing 1.00 mg·L-1 2,4-D 0.50 BA. time subculture 20 - 25 d. results showed contents decreased gradually at beginning differentiation. Vigorous friable used culture. Study effect hormone...
UV-B radiation and drought majorly restrict plant growth, particularly in summer. ELONGATED HYPOCOTYL 5 (HY5), a bZIP transcription factor (TF), has beneficial impact on photomorphogenesis. However, the sequence of
The TEOSINTE BRANCHED1, CYCLOIDEA, and PROLIFERATION CELL FACTOR (TCP) transcription factor is a plant-specific gene family acts on multiple functional genes in controlling growth, development, stress response, the circadian clock. In this study, class I member of TCP from Fraxinus mandshurica Rupr. was isolated named FmTCP15, which encoded protein 362 amino acids. Protein structures were analyzed five ligand binding sites predicted. phylogenetic relationship showed that FmTCP15 most closely...
The genetic stability of exogenous genes in the progeny transgenic trees is extremely important forest breeding; however, it remains largely unclear. We selected birch ( Betula platyphylla ) and its hybrid F1 to investigate expression silencing mechanism genes. found that could be transmitted their offspring through sexual reproduction. were segregated during transmission. WT1×TP22 (184) WT1×TP23 (212) showed higher Bgt greater insect resistance than parents. However, TP23×TP49 (196) much...
Plant leaves, as one of the main organs plants, have a crucial impact on plant development. In hybrid F1 variety, clone “1601” from hybridization Fraxinus mandshurica Rupr. × sogdiana Bunge was showed significant differences in leaf development with its female control “M8”. The phenotypic leaflets and fronds, photosynthesis parameters, rate water loss cell size were investigated between 1601 M8. details that significantly smaller (leaflet 53.78% M8) rounder aspect ratio 66.97% M8). Its...
We analysed NO, reactive oxygen species (ROS) and Ca2+ crosstalk during triterpenoid biosynthesis in white birch (Betula platyphylla Suk.) cells. Cells were pretreated with diphenyleneiodonium, sodium diethyldithiocarbamate (DDTC) or catalase (CAT), a channel blocker chelator before nitroprusside treatment. Changes triterpenoid, malondialdehyde proline levels, cell viability, CAT, ascorbate peroxidase activity recorded. Furthermore, enzyme gene expression levels related to triterpene...
With the continuous increase in atmospheric carbon dioxide emissions, nitrogen (N) and phosphorus (P) as mineral elements increasingly restrict plant growth. To explore effect of deficiency P N on growth physiology, Fraxinus mandshurica (hereafter “F. mandshurica”) Rupr. annual seedlings Wuchang (WC) provenance with fast Dailing (DL) slow were treated complete nutrition or starvation (N-), (P-) both (NP-). Although P- N- increased use efficiency (PUE) (NUE), respectively, they reduced leaf...
Study on the characteristics of integration and expression is basis genetic stability foreign genes in transgenic trees. To obtain insight into relationship transgene copy number level, we screened 22 birch lines. Southern blot analysis plants indicated that bgt varies from one to four, which 18.2% were single copy. Copy gus was different 68% plants, indicating rearrangement or partial deletion appeared process T-DNA integration. Transcriptional gene analyzed by Northern blot. TGS has been...
