Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Microbe-Plant Interactions

Microbe-Plant Interactions

Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...

Production of Biopesticides

Production of Biopesticides

Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...

Background:

The brown planthopper (Nilaparvata lugens, BPH) is a major global rice pest causing significant economic damage.
Advancements in high-throughput sequencing have enabled detailed studies of BPH biology, including its genome and gene expression.
Understanding BPH biology is crucial for developing effective pest management and identifying resistant rice varieties.

Purpose of the Study:

To review recent advances in applying omics technologies to study BPH.
To highlight the integration of omics data for understanding BPH virulence and host interactions.
To explore the potential of omics for developing sustainable pest management strategies.

Main Methods:

Genomic sequencing, transcriptomics, proteomics, and metabolomics provide insights into BPH biology.
Single-cell RNA-seq and advanced genome assembly refine understanding of gene regulation and cell-specific functions.
Metagenomic approaches characterize symbiotic microbial communities and their role in BPH virulence.

Main Results:

Omics data integration reveals complex genetic interactions and population dynamics in BPH.
Post-transcriptional modifications, non-coding RNAs, and epigenetic variations influence host-BPH interactions.
Symbiotic microbes enhance BPH virulence, offering targets for plant protection.

Conclusions:

Diverse omics approaches collectively elucidate BPH virulence mechanisms.
Findings support the deployment of BPH resistance in rice breeding programs.
Manipulating host-microbe interactions presents novel opportunities for sustainable BPH management.
