Comprehensive analysis of the gene family in tobacco and functional characterization of involvement in amino acids homeostasis.

Amino acids are vital nitrogen (N) sources for plant growth, development, and yield. The uptake and translocation of amino acids are mediated by amino acid transporters (AATs). The AATs family including lysine-histidine transporters (LHTs), amino acid permeases (AAPs), and proline transporters (ProTs) subfamilies have been identified in various plants.

Comparative Chloroplast Genomes of Species (Solanaceae): Insights Into the Genetic Variation, Phylogenetic Relationship, and Polyploid Speciation.

L. is a genus rich in polyploidy, which represents an ideal natural system for investigating speciation, biodiversity, and phytogeography. Despite a wealth of phylogenetic work on this genus, a robust evolutionary framework with a dated molecular phylogeny for the genus is still lacking.

NtNAC053, A Novel NAC Transcription Factor, Confers Drought and Salt Tolerances in Tobacco.

The NAC (NAM, ATAF1/2, and CUC2) family acts as one of the largest families of the transcription factor in the plant kingdom and was revealed to function as the important regulators in various environmental stresses. However, a few studies were reported about the biofunctions of the NAC transcription factor in tobacco. In the current study, we characterized a novel NAC transcription factor encoding the gene in tobacco, which was significantly up-regulated when exposed to salt and drought treatments.

Comprehensive Analysis of Long Non-coding RNA Modulates Axillary Bud Development in Tobacco ( L.).

Long non-coding RNAs (lncRNAs) regulate gene expression and are crucial for plant growth and development. However, the mechanisms underlying the effects of activated lncRNAs on axillary bud development remain largely unknown. By lncRNA transcriptomes of axillary buds in topped and untopped tobacco plants, we identified a total of 13,694 lncRNAs.

Genome-Wide Identification and Characterization of Gene Family in .

The gibberellic acid stimulated Arabidopsis () gene family is critical for plant growth, development, and stress response. gene family has been studied in various plant species, however, the gene family in tobacco () have not been characterized in detail. In this study, we identified 18 genes in the tobacco genome, which were distributed to 13 chromosomes.

Genome-wide characterization and expression profiling of the PDR gene family in tobacco (Nicotiana tabacum).

The pleiotropic drug resistance (PDR) proteins of the ATP-binding cassette (ABC) family play essential roles in physiological processes and have been characterized in many plant species. However, no comprehensive investigation of tobacco (Nicotiana tabacum), an important economic crop and a useful model plant for scientific research, has been presented. We identified 32 PDR genes in the tobacco genome and explored their domain organization, chromosomal distribution and evolution, promoter cis-elements, and expression profiles.

[Ecological reasons for the difference in nicotine content of flue-cured tobacco planted in different regions of Hunan Province].

Aimed to explore the ecological reasons for the difference in nicotine content of flue-cured tobacco planted in different regions of Hunan Province, field experiments were conducted in Sangzhi, Liuyang, and Yongzhou counties, the three typical tobacco regions of Hunan Province, taking tobacco variety K326 as the test object. Simultaneously, pot experiments with local soils and guest soils were carried out. The nicotine content of mid position tobacco leaves was analyzed at harvest time.
