Plant Stress Resistance Analysis – Transcriptomic Biomarkers

Plant resistance to stress is crucial for survival in harsh environmental conditions such as drought, salinity, extreme temperatures, or pathogen attacks. Gene expression analysis helps identify biomarkers associated with plant defense mechanisms against various stress types.

Genes Analyzed in Plant Stress Resistance

Our panel targets key biomarkers involved in responses to abiotic and biotic stress, including:

• DREB1 (Dehydration Responsive Element Binding 1) – Transcriptionally activated during water stress, playing a key role in drought response

• LEA (Late Embryogenesis Abundant Proteins) – Proteins linked to drought and salt stress tolerance, protecting plant cells under extreme conditions

• NPR1 (Nonexpressor of Pathogenesis-Related genes 1) – A key gene in plant response to fungal and bacterial pathogens

• P5CS (Δ1-Pyrroline-5-Carboxylate Synthase) – Enzyme involved in proline synthesis, an osmoprotectant aiding plant resistance to salinity and drought

• CYP450 (Cytochrome P450) – Enzyme involved in the biosynthesis of defense compounds and response to abiotic stress such as UV and toxins

• HSP70 (Heat Shock Protein 70) – Heat shock protein that protects cellular proteins during thermal stress and assists in protein folding

• RBOH (Respiratory Burst Oxidase Homolog) – Enzyme involved in reactive oxygen species (ROS) production during stress, playing a role in pathogen defense

• MAPK (Mitogen-Activated Protein Kinase) – Signaling pathway involved in plant response to biotic and abiotic stress

• Atf (Activation Transcription Factor) – Transcription factor regulating stress defense genes

• SOD (Superoxide Dismutase) – Enzyme reducing ROS-induced damage, protecting plant cells from environmental stress

Applications & Benefits

• Crop improvement – Biomarker analysis helps develop plant varieties resistant to extreme climates and pathogens

• Irrigation management optimization – Identifies plants best adapted to dry environments and optimizes water-use strategies

• Selection of stress-resistant plants – Assists genetic selection of new plant varieties resistant to abiotic (drought, salinity) and biotic (insects, fungi) stresses

• Climate change monitoring – Tracks climate change impact on plants by analyzing stress resistance genes

• Crop protection against diseases and pests – Enhances crop resistance through a deeper understanding of underlying biological mechanisms

Technologies Used

We employ cutting-edge technologies for precise analysis of stress resistance biomarkers:

• RT-qPCR and RNA-seq (NGS) – Quantifies gene expression involved in stress response

• Immunohistochemistry – Measures protein expression related to plant defense

• Multiplexed technologies (e.g., Nanostring) – Enables simultaneous analysis of stress resistance biomarkers

• Field trials – Assesses the impact of treatments on plant stress resistance gene expression
