If a plant experiences herbivore damage, which consequence follows due to induced phytoalexin production?

💡 Explanation

Phytoalexins are antimicrobial and antioxidative compounds synthesized by plants in response to stress; their accumulation leads to localized cell death, limiting pathogen spread, because the hypersensitive response sacrifices infected cells rather than allowing systemic infection. Therefore localized cell death protects the plant tissue, rather than enhancing photosynthesis, water uptake, or nutrient absorption.

• A new flu vaccine contains mRNA encoding viral proteins. Which mechanism explains why this vaccination leads to long-term protection?
• If bacteria within a biofilm experience nutrient scarcity, which consequence related to their group coordination is most likely?
• An intestinal epithelial cell activates the KRAS oncogene due to a mutation. Which outcome is most likely?
• If a mosquito infected with malaria initially probes a host but fails to draw blood, which consequence follows?
• If a tRNA molecule's anticodon is 3'-AUG-5', which amino acid would it deliver during translation, assuming no post-translational modifications?
• A caterpillar consumes oak leaves, triggering a defense response. Which outcome occurs when methyl jasmonate signaling increases in the plant?
