TL;DR: In this article, the CsDGAT1-B gene was identified and a nucleotide sequence of the CdGAT 1-B was shown in SEQ ID No.1 and an amino acid sequence was shown by SEQ No.2.
Abstract: The present invention belongs to the technical field of plant salt resistance genes and particularly relates to camelina sativa CsDGAT genes and applications thereof in plant salt resistance. The camelina sativa CsDGAT gene is CsDGAT1-B, and a nucleotide sequence of the CsDGAT1-B is shown in SEQ ID NO.1 and an amino acid sequence is shown in SEQ ID NO.2. Functional analysis and identification of the CsDGAT genes provide a theoretical basis for obtaining new plant varieties, and the genes are used to conduct molecular breeding to be expected to cultivate high-oil plants with production and application value and lay theory and production practices for breeding new varieties of salt-tolerant transgenic crops.

TL;DR: In this paper, the utility of different molecular markers for identification and taxonomic classification in bamboos is discussed. But, the taxonomy of bamboo is highly unstable due to its inappropriate flowering cycle as well as widespread polyploidization of the genome.
Abstract: Bamboo (family: Poaceae) is a cash crop, and due to its economic benefit, this gift of nature is considered as “green gold.” This widely distributed plant group is facing concern regarding its conservation due to its continually increasing demand. The successful conservation of plant species lies in proper identification and characterization. In the case of bamboo, as the flowering cycle is long, the identification and taxonomical classification is dependent on mainly its vegetative features like culm and culm-sheath characters. Due to its inappropriate flowering cycle as well as widespread polyploidization of the genome, the taxonomy of bamboo is highly unstable. The molecular techniques in taxonomic classification have been employed since its discovery as it is not influenced by external factors. Molecular taxonomy can resolve many discrepancies regarding the classification and identification of genotypes which are long-standing and could not be solved based on phenotypic characters. Molecular descriptors such as hybridization-based marker like restriction fragment length polymorphism (RFLP) or polymerase chain reaction (PCR)-based markers like random amplified polymorphic DNA (RAPD), inter simple sequence repeat (ISSR), simple sequence repeat (SSR), sequence characterized amplified regions (SCARs), and amplified fragment length polymorphism (AFLP) or sequence-based marker like single-nucleotide polymorphism (SNP), diversity array technology (DArT), etc. are used to evaluate the genetic diversity as well as for accurate identification of the bamboo species. The present study will elaborate on the utility of different molecular markers for identification and taxonomic classification in bamboos.

TL;DR: In this paper, the microRNA gene (PbrmiR397a) is separated from Dangshan pear and has a function of regulating pear fruit sclereid development, and a precursor nucleotide sequence of the gene is shown as SEQ ID No.1.
Abstract: The invention discloses pear PbrmiR397a and application thereof. The microRNA gene (PbrmiR397a) is separated from Dangshan pear and has a function of regulating pear fruit sclereid development, and a precursor nucleotide sequence of the gene is shown as SEQ ID No.1. PbrmiR397a is converted into tobacco through an agrobacterium-mediated genetic transformation method to obtain a transgenic plant, biological function verification shoes that the cloned PbrmiR397a gene has a function of reducing lignin synthesis. A new gene resource is provided for molecular breeding with lignin synthesis reduced by the finding of the PbrmiR397a. The PbrmiR397a gene has the advantage of targeting and regulating multiple genes at the same time, so that a more efficient approach is provided for molecular breeding.
