Sequential measurements were made of the free amino-acid pool in the premitotic region of microspores of Lilium longiflorum. The basic amino acid arginine appears in the pool and then disappears. Arginine appears at the same developmental stage at which it has been reported that the free
From the dried bulbs of the lily (Lilium brownii), a protein with strong antifungal and mitogenic activities was isolated. It also exhibited an inhibitory action on the activity of HIV-1 reverse transcriptase. The protein was single-chained and possessed a molecular weight of 14.4 kDa and an
When bulb-scale segments of Lilium longiflorum were cultured on a medium containing auxin and cytokinin, the proportion of the expiants with newly-formed bulblets was significantly increased by the application of different polyamines. The most effective polyamine was spermine, where more than 90% of
Some guanidino compounds have been found to inhibit spontaneous mammary tumourigenesis in mice. In the present study, the effects of chronic treatment with Gold Banded Lily (Lilium auratum LindI) or Chinese Milk Vetch (Astragalus sinicus L), which contains L-arginine or L-canavanine, on spontaneous
