Cattleya intermedia is an Atlantic Forest species endemic to Brazil that is classed as vulnerable on the list of threatened species. In this study, C. intermedia plantlets were micropropagated in an asymbiotic culture and the influence of different concentrations of sucrose (15, 30, 45 and 60 g L-1, plus a zero sucrose medium) and macronutrient salts (complete Murashige and Skoog (MS) medium an...

The present study was performed to unravel the mechanisms of systemic acquired resistance (SAR) establishment and resistance signaling pathways against the canker-rot fungus (Inonotus obliquus strain IO-U1) infection in Japanese birch plantlet No.8. Modulation of protein-profile induced by salicylic acid (SA)-administration was analyzed, and SA-responsive proteins were identified. In total, 5 s...

The aim of the research work was to study the genetic variability of sunflower (Heliantus annuus L.) seeds collection. From 1500 available genotypes a set of 120 recombinant inbred lines coming from different countries were selected to perform the study. The genetic variability consisted in two types of experiments: in vivo and in vitro cultures. The recombinant inbred lines were classified usi...

The present study was undertaken to investigate the role of banana extract (BE) on synchronous plantlet formation from seeds of Dendrobium lituiflorum Lindl. The seedlings formed on modified Knudson C (KC) medium supplemented with 20% (v/v) BE had significantly high fresh and dry weights. Morphologically uniform plantlets with elongated leaves and well developed roots were formed on KC medium w...
