Rostlinný hormon auxin je známý jako regulátor prodlužování stonku a (ne)aktivity postranních pupenů. Ve skutečnosti ale dokáže mnohem více. Ovšem jen za předpokladu, že se ho správné množství vyskytuje ve správném místě a čase. Příjem auxinového signálu zajišťují receptory uvnitř buňky i na jejím povrchu., The plant hormone auxin is a long-known regulator of shoot elongation and auxiliary bud (in)activity. But there is much more about it – if the right amount of auxin appears at the right place and time. The auxin signal is perceived by both intracellular and surface receptors., and Jiří Libus.
World of RNA. In last 10-15 years RNA molecules has emerged as stars on the cell biology sky. They participate and regulate almost every step in the gene expression pathway. The role of RNA begins with regulation via catalysis of RNA splicing and translation and finishes with RNA degradation. In addition, small variations in RNA processing can result in dramatic changes in the phenotype and might explain differences between organisms with very similar genomes.
