壳聚糖纳米粒子通过基因表达调控提高番茄的抗旱性

背景干旱浪潮目前正在侵袭世界并影响作物生产。这样的问题需要不断的研究，在不影响生产力的情况下开发出更具耐受性的植物。在本研究中，研究了壳聚糖纳米颗粒（CHNPs）对番茄中四个干旱反应基因HsfA1a、SlAREB1、LeNCED1和LePIP1表达的影响。为此，制备了壳聚糖纳米粒子，并对其理化性质进行了表征。然后，在含有60或90 ppm CHNPs的土壤中培养番茄幼苗。结果表明，成功制备了平均尺寸为92–404 nm、ζ电位为+29.20 mV的CHNPs。基因表达分析显示，与干旱胁迫相比，在两种CHNPs浓度下，所有测试基因的表达都显著上调。结论CHNPs可用于提高番茄的抗旱性。

期刊介绍： Plant Gene publishes papers that focus on the regulation, expression, function and evolution of genes in plants, algae and other photosynthesizing organisms (e.g., cyanobacteria), and plant-associated microorganisms. Plant Gene strives to be a diverse plant journal and topics in multiple fields will be considered for publication. Although not limited to the following, some general topics include: Gene discovery and characterization, Gene regulation in response to environmental stress (e.g., salinity, drought, etc.), Genetic effects of transposable elements, Genetic control of secondary metabolic pathways and metabolic enzymes. Herbal Medicine - regulation and medicinal properties of plant products, Plant hormonal signaling, Plant evolutionary genetics, molecular evolution, population genetics, and phylogenetics, Profiling of plant gene expression and genetic variation, Plant-microbe interactions (e.g., influence of endophytes on gene expression; horizontal gene transfer studies; etc.), Agricultural genetics - biotechnology and crop improvement.
