Percentage tip necrosis in bean (Phaseolus vulgaris) induced by bean yellow mosaic virus (BYMV) infection increased between 16 and 24 degree C and decreased to near zero above 28 degree C. Plants that failed to develop tip necrosis at 32 degree C did so within 4 to 5 days when moved to 24 degree C. The development of tip necrosis appeared to be associated with virus multiplication. A tip necrosis-inducing substance (TNIS) might be responsible for the tip necrosis TNIS was shown to induce cellular leakage from the infected plants, which might be conducive to tip necrosis, and was seemingly inhibited at a temperature higher than 28 degree C. The inhibition of tip necrosis in BYMV-infected plants coincided with an exponential increase of acid phosphatase activity, suggesting that lysosomes are involved. Further investigation is being undertaken to isolate and characterize the potential TNIS and to identify the enzyme(s) which might be responsible for its degradation eng
