Frost sensitivity of Zea mays increased by application of Pseudomonas syringae

摘要: DRIED, powdered corn leaves (Zea mays L.) dusted on to the of seedlings, will increase frost damage treated seedlings relative untreated controls at ∼ −4°C (refs 1, 2). In a preliminary attempt isolate entity responsible for this activity, we found that water extracts leaf powder from healthy field-grown plants caused as much in sensitivity when applied spray seedling corn, did application itself tested described below. Addition either streptomycin or tetracycline (1,000 p.p.m.) these eliminated their suggesting possible role bacteria effect.
