Evolution of RGF/GLV/CLEL Peptide Hormones and Their Roles in Land Plant Growth and Regulation.

Rooting is a key innovation during plant terrestrialization. RGFs/GLVs/CLELs are a family of secreted peptides, playing key roles in root stem cell niche maintenance and pattern formation. The origin of this peptide family is not well characterized.

A Comparative Analysis of Transcription Networks Active in Juvenile and Mature Wood in .

Juvenile wood (JW) and mature wood (MW) have distinct physical and chemical characters, resulting from wood formation at different development phases over tree lifespan. However, the regulatory mechanisms that distinguish or modulate the characteristics of JW and MW in relation to each other have not been mapped. In this study, by employing the trees with an identical genetic background, we carried out RNA sequencing (RNA-seq) and whole genome bisulfite sequencing (WGBS) in JW and MW forming tissue and analyzed the transcriptional programs in association with the wood formation in different phrases.

A Novel Gene Coding γ-Aminobutyric Acid Transporter May Improve the Tolerance of to Adverse Environments.

Novel genes provide important genetic resource for organism innovation. However, the evidence from genetic experiment is limited. In plants, γ-aminobutyric acid (GABA) transporters (GATs) primarily transport GABA and further involve in plant growth, development, and response to various stresses.

Genome-Wide Identification of Long Noncoding RNAs and Their Responses to Salt Stress in Two Closely Related Poplars.

Long noncoding RNAs (lncRNAs) are involved in various biological regulatory processes, but their roles in plants resistance to salt stress remain largely unknown. To systematically explore the characteristics of lncRNAs and their roles in plant salt responses, we conducted strand-specific RNA-sequencing of four tissue types with salt treatments in two closely related poplars ( and var. ), and a total of 10,646 and 10,531 lncRNAs were identified, respectively.

Transcriptomic Analysis of Seed Germination Under Salt Stress in Two Desert Sister Species ( and ).

As a major abiotic stress, soil salinity limits seed germination and plant growth, development and production. Seed germination is highly related not only to the seedlings survival rate but also subsequent vegetative growth. and are closely related species that show a distinguished adaptability to salinity stress.

Development of SSR markers from transcriptomes for (Poaceae), an endemic of the Qinghai-Tibetan Plateau.

Premise Of The Study: Transcriptomes were used to develop microsatellite markers for the plant genus (Poaceae), which comprises three species of grasses (. , . , and .

Identification of 4CL Genes in Desert Poplars and Their Changes in Expression in Response to Salt Stress.

4-Coumarate:CoA ligase (4CL) genes are critical for the biosynthesis of plant phenylpropanoids. Here we identified 20 4CL genes in the genomes of two desert poplars (Populus euphratica and P. pruinosa) and salt-sensitive congener (P.

Transcriptome dynamics of a desert poplar (Populus pruinosa) in response to continuous salinity stress.

Using RNA sequencing analysis, we identified 9,216 regulatory and salt-related genes with differential expression and temporal expression trends which provide a clear picture of transcriptomic dynamics in response to continuous salinity stress in a desert poplar, Populus pruinosa. Populus pruinosa Schrenk is native to the desert region of western China and extraordinarily well adapted to the local salt stress. Thus, it is an ideal model for studying plants' adaptation to salt stress, but its transcriptomic responses have not been previously characterized.

Genome-wide variation within and between wild and domestic yak.

The yak is one of the few animals that can thrive in the harsh environment of the Qinghai-Tibetan Plateau and adjacent Alpine regions. Yak provides essential resources allowing Tibetans to live at high altitudes. However, genetic variation within and between wild and domestic yak remain unknown.

Genomic insights into salt adaptation in a desert poplar.

Despite the high economic and ecological importance of forests, our knowledge of the genomic evolution of trees under salt stress remains very limited. Here we report the genome sequence of the desert poplar, Populus euphratica, which exhibits high tolerance to salt stress. Its genome is very similar and collinear to that of the closely related mesophytic congener, P.
