Somatic embryogenesis in Arabidopsis is achieved by culturing bending-cotyledon embryos on a 2,4-D-containing induction medium for 14 d followed by a transfer on to a hormone-free development medium. Several genes orthologous to Arabidopsis SHOOTMERISTEMLESS (STM), CLAVATA 1 (CLV1), and ZWILLE (ZLL) were isolated from Brassica oleracea (Bo), B. rapa (Br), and B. napus (Bn), and ectopically expr...

Studies of the anther transcriptome on non-model plants without a known genome are surprisingly scarce. RNA-Seq and digital gene expression (DGE) profiling provides a comprehensive approach to identify candidate genes contributing to developmental processes in non-model species. Here we built a transcriptome library of developing anthers of Hamelia patens and analyzed DGE profiles from each sta...

Lipid transfer proteins (LTPs) are small secretory proteins in plants with defined lipid-binding structures for possible lipid exocytosis. Special groups of LTPs unique to the anther tapetum are abundant, but their functions are unclear. We studied a special group of LTPs, type III LTPs, in Arabidopsis (Arabidopsis thaliana). Their transcripts were restricted to the anther tapetum, with levels ...

the present study reports an efficient protocol for isolation and regeneration of protoplasts from callus of fritillaria imperialis l. there is no published method recommended for protoplast isolation and regeneration from fritillaria imperialis l. a range of factors, which influence the success of isolation and regeneration of f. imperialis protoplasts, were investigated. from the results obta...
