is a basic helix-loop-helix transcription factor that confers enhanced root growth and tolerance to salt stress in poplar.

The basic helix-loop-helix (bHLH) family of transcription factors is one of the largest and oldest transcription factor families in plants. Members of the bHLH family regulate various growth and metabolic processes in plants. We used quantitative trait locus (QTL) mapping and transcriptome sequencing (RNA-seq) to identify as a candidate bHLH transcription factor associated with root dry weight (RDW) in poplar.

Gene Positively Regulate Salt Tolerance in Transgenic × .

Salt is an important environmental stress factor, which seriously affects the growth, development and distribution of plants. Chlorophyllase plays an important role in stress response. Nevertheless, little is known about the physiological and molecular mechanism of chlorophyll (Chlase, ) genes in plants.

Genome-Wide Analysis of the Gene Family in and Functional Analysis of in Root Growth and Amino Acid Transport.

The adventitious root (AR) is the basis for successful propagation by plant cuttings and tissue culture and is essential for maintaining the positive traits of a variety. Members of the amino acid/auxin permease (AAAP) gene family play indispensable roles in various plant metabolisms and have few studies on root growth and amino acid transport. In this study, with a systematic bioinformatics analysis of the AAAP family, 83 were identified from and grouped into 8 subfamilies.

Transcriptome Analysis of under Salt Treatment and Gene Enhances Salt Tolerance in Transgenic × .

is mainly distributed in desert environments with dry and hot climate in summer and cold in winter. Compared with other poplars, is more resistant to salt stress. It is critical to investigate the transcriptome and molecular basis of salt tolerance in order to uncover stress-related genes.

An Efficient -Mediated Transformation Method for Hybrid Poplar 84K ( × ) Using Calli as Explants.

A highly efficient -mediated transformation method is needed for the molecular study of model tree species such as hybrid poplar 84K ( × cv. '84K'). In this study, we report a callus-based transformation method that exhibits high efficiency and reproducibility.

Genome-Wide Identification of Long Non-Coding RNAs and Their Potential Functions in Poplar Growth and Phenylalanine Biosynthesis.

Poplar is an important bioenergy tree species. lncRNAs play important roles in various biological regulatory processes, and their expression pattern is more tissue-specific than mRNAs. In this study, P.

Leaf Size Development Differences and Comparative Trancriptome Analyses of Two Poplar Genotypes.

The plant leaf, the main organ of photosynthesis, is an important regulator of growth. To explore the difference between leaf size of 'Danhong' (Pd) and 'Tongliao1' (Ps), we investigated the leaf length, leaf width, leaf thickness, leaf area, leaf mass per area (LMA), and cell size of leaves from two genotypes and profiled the transcriptome-wide gene expression patterns through RNA sequencing. Our results show that the leaf area of Pd was significantly larger than that of Ps, but the epidermal cell area was significantly smaller than that of Ps.
