Abstract
Background
O-acetylation of cell wall polysaccharides is determined by plant species and tissue type and plays an instrumental role in the growth of plant cells and their interaction with the environment. The trichome birefringence-like (TBL) gene family encodes the acetyltransferases that facilitate O-acetylation. However, no report on the TBL gene family in tobacco (Nicotiana tabacum) can be found.
Results
In this study, 130 TBL genes were identified and characterized; they are distributed across all 24 tobacco chromosomes. Analysis of gene structure and conserved domains and motifs identified five groups of N. tabacum TBL genes (NtTBL). The NtTBL genes underwent segmental duplication and purifying selection. Functional analysis of cis-elements, interaction networks, and expression patterns of NtTBL genes indicated their significant roles in growth and development and stress responses. Furthermore, we validated the pivotal role of NtTBL31 in tobacco growth and drought resistance.
Conclusions
This study lays a foundation for further functional characterization of the TBL gene family in tobacco.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
