As part of our studies on the physiological and ecological function of caffeine, we investigated the effect of exogenously supplied caffeine on purine, pyrimidine and pyridine metabolism in rice seedlings. We examined the effect of 1 mM caffeine on the in situ metabolism of 14C-labelled adenine,
The effect of 100 ppm solution of each of kinetin, adenine, uracil and thymine on the vegetative and reproductive growth of Cucumis sativus, phaseolus mungo, Oryza sativus, Raphanus sativus and Lycopersicum esculentum plants were studied. The rate of vegetative growth was found to be more in the
Lariats are formed by excised introns, when the 5' splice site joins with the branchpoint (BP) during splicing. Although lariat RNAs are usually degraded by RNA debranching enzyme 1, recent findings in animals detected many lariat RNAs under physiological conditions. By contrast, the features of BPs
