Transcriptomic Insights: Phytogenic Modulation of Buffel Grass (Cenchrus ciliaris) Seedling Emergence

Area of Science:

• Agricultural Science
• Plant Biology
• Molecular Biology

Background:

• Buffel grass (Cenchrus ciliaris) is a vital forage grass.
• Enhancing seedling establishment is critical for agricultural productivity.
• Novel phytogenic products offer sustainable alternatives for crop improvement.

Purpose of the Study:

• To evaluate the effect of a novel phytogenic product on buffel grass seedling emergence.
• To determine the optimal concentration of the phytogenic product for seedling establishment.
• To investigate the molecular mechanisms underlying the phytogenic product's effects using transcriptomics.

Main Methods:

• A dilution series of a phytogenic product (citric acid, carvacrol, cinnamaldehyde) was tested.
• Buffel grass seedling emergence was measured at different concentrations.
• RNA sequencing (RNA-seq) was employed to analyze gene expression changes in seedlings.

Main Results:

• An optimal phytogenic product concentration of 0.5% significantly promoted buffel grass seedling emergence.
• Transcriptomic analysis revealed a significant increase in overall transcriptional activity compared to controls.
• Key metabolic pathways, including the tricarboxylic acid (TCA) cycle, glycolysis, and pentose phosphate pathways, were positively modulated.

Conclusions:

• The novel phytogenic product effectively enhances buffel grass seedling establishment.
• The product's mechanism involves stimulating energy metabolism and essential biosynthetic pathways.
• This research provides molecular insights into phytogenic compounds for sustainable agriculture.
