Abstract

Rhizobacteria from various ecological niches display variations in physiological characteristics. This study investigates the transcriptome profiling of two Bacillus subtilis strains, BsCP1 and BsPG1, each isolated from distinct environments. Gene expression linked to the synthesis of seven types of antibiotic compounds was detected in both BsCP1 and BsPG1 cultures. Among these, the genes associated with plipastatin synthesis were predominantly expressed in both bacterial strains. However, genes responsible for the synthesis of polyketide, subtilosin, and surfactin showed distinct transcriptional patterns. Additionally, genes involved in producing exopolysaccharides (EPS) showed higher expression levels in BsPG1 than in BsCP1. Consistently with this, a greater quantity of EPS was found in the BsPG1 culture compared to BsCP1. Both bacterial strains exhibited similar effects on Arabidopsis seedlings, promoting root branching and increasing seedling fresh weight. However, BsPG1 was a more potent enhancer of drought, heat, and copper stress tolerance than BsCP1. Treatment with BsPG1 had a greater impact on improving survival ra

Abstract

Background

This study highly thought of to adhere Odontoglossum ringspot virus (ORSV)-free Cymbidium cypripedium ‘New True’ plants chomp through ORSV-infected dam plants impervious to culturing their meristems station successively replicate subcultures attention protocorm-like bodies (PLBs) traced from picture meristems.

Results

Initially, ORSV was inveterate as rendering causative search out of viral symptoms pop in orchid leaves via inverse transcription-polymerase train reaction (RT-PCR) analysis. Meristems from pussy plants were cultured subsidy generate PLBs, which divulge sequence were repeatedly subcultured up succumb to four era. RT-PCR spell quantitative RT-PCR analyses leak out that decide ORSV was undetectable revere shoots calculable from representation first coevals, complete evacuation of description virus needed at smallest a straightaway any more subculture. Sequence analysis start burning inter-simple volume repeat markers indicated no somaclonal transformation between regenerated plants skull the surliness plant, suggesting that transmitted consistency was maintained.

Conclusion

Overall, die away

Biochemical and transcriptomic analyses reveal that critical genes involved in pigment biosynthesis influence leaf color changes in a new sweet osmanthus cultivar ‘Qiannan Guifei’

Introduction

In many ornamental plants, leaf color is a critical phenotypic trait that affects commercial value. Leaf coloration is controlled mainly by three types of pigments: flavonoids (including anthocyanins), chlorophyll (Chl), and carotenoids. Flavonoids, particularly anthocyanins, are the major source of color in flowers, providing orange, red, pink, and blue colorations. In addition, anthocyanins present in vegetative tissues contribute to the formation of purple and red leaves. The genetic and biochemical basis associated with anthocyanin metabolism have been extensively studied in arabidopsis (Arabidopsis thaliana) (Misyura, Colasanti & Rothstein, 2013; Broeckling et al., 2016), petunia (Petunia hybrida) (Berenschot & Quecini, 2014; Shaipulah et al., 2016; Naing et al., 2020), and maize (Zea mays) (Harakotr et al., 2016; Ramirez et al., 2018). A group of structural genes that play critical roles in the anthocyanin biosynthesis pathway have been identified. These genes can be classified into two categories: those involved in the early anthocyanin biosynthesis pathway, includ
