Herbivore-deterring trichomes persist with the help of Woolly and Get02
Plant Science Research WeeklyType-IV glandular trichomes, which produce acylsugars, are effective deterrents against herbivory in Solanum, but they only persist in the juvenile stage of the cultivated tomato (S. lycopersicum). Therefore, these trichomes serve as a marker for the transition from juvenile to adult phases in developmental…
Always prepared: priming of the defense response by trichomes (Nature Comms)
Plant Science Research WeeklyRain contributes to plant disease. Rain can contain high concentrations of pathogens (like Pseudomonas, Xanthomonas, Alternaria, Fusarium sp., etc.), and high humidity associated with rain antagonizes stomatal closure, leaving open entry points for some pathogens. Matsumura and colleagues have demonstrated…
