The role of auxins and cytokinins in the mutualistic interaction between Arabidopsis and Piriformospora indica
Original language description
Arabidopsis growth and reproduction are stimulated by the endophytic fungus Piriformospora indica. The fungus produces low amounts of auxins, but the auxin levels and the expression of auxin-regulated genes are not altered in colonized roots. Also, mutants with reduced auxin levels (ilr1-1, nit1-3, tfl2, cyp79 b2b3) respond to P. indica. However, the fungus rescues the dwarf phenotype of the auxin overproducer sur1-1 by converting free auxin into conjugates, which also results in the downregulation of the auxin-induced IAA6 and the upregulation of the P. indica?induced LRR1 gene. The fungus produces relatively high levels of cytokinins, and the cytokinin levels are higher in colonized roots compared with the uncolonized controls. trans-Zeatin cytokininbiosynthesis and the CRE1/AHK2 receptor combination are crucial for P. indica?mediated growth stimulation, while mutants lacking cis-zeatin, impaired in other cytokinin receptor combinations, or containing reduced cytokinin levels respon

Role auxinů a cytokininů ve vzájemné interakci mezi Arabidopsis a Piriformospora indica
Czech description
Byl studován vliv endofytní houby Piriformospora indica na růst a reprodukci Arabidopsis. Byly měřeny hladiny auxinů a cytokininů u houby, v nenapadených i napadených kořenech Arabidopsis (mutantech i netransgenních rostlinnách), výsledky porovnány a diskutovány. Nakonec, srovnávací analýza fytohormonových mutantů vedla k závěru , že odpověď na P. indica je nezávislá na stavbě i velikost kořenů.
