Abstract:
... In this work, the effect of lead on sunflower seedlings with two root system types: primary — formed from embryonic tissues and adventitious - originating from hypocotyl after cutting off primary roots was investigated. The seedlings were subjected to Pb(NO3)2 in doses: 0, 0.5, 2.5, 5 and 20 mg(Pb) dm−3 for a week. Lead accumulation, seedling length and mass as well as selected parameters repr ...

Abstract:
... LAF1 (Long after far-red radiation 1) is a R2R3 Myb transcription factor and a signal transducer of far-red radiation. To investigate the role of LAF1 in leaf and root development, the leaf growth and vein patterning in laf1 mutants under short day conditions were examined. The length of rosette leaves was reduced and the width of the midvein was increased in laf1 mutants compared to their wild-ty ...
