| Background: An adaptive mechanism in plant roots is initiated in the event of nitrogen and potassium deficiency, and it facilitates the active uptake of these elements in order to ensure plant growth and survival in stress conditions. Signaling and transduction of signals in response to changing nitrogen and potassium concentrations is a complex process, affected by interactions between various gene expression products, and often subjected to modifications. Results: In order to identify genotypic differences between phenotypes of two populations of recombinant inbred rye lines (153/79-1 x Ot1-3 and Ot0-6 x Ot1-3) in response to nutrition stress caused by nitrogen and potassium deficiency at the seedling stage, bulk segregant analysis was utilized.... |

| Background: Plants differ in the methods used to acquire nutrients from environments with low nutrient availability, and may change the morphology of their root architecture to be able to take up nutrients. Results: In the present study rye response to stress caused by high and low nitrogen-potassium treatments in mature embryos cultures was described within a population consisting of one hundred and thirty eight recombinant inbred lines of rye. Characterization of the response of recombinant inbred lines (RILs) to nutrient stress was presented as the results of analyses of morphological traits, and physiological and biochemical parameters of the seedlings grown in both treatments. A wide range of variability of individual RILs to induced stress was... |
