Sažetak
In monocotyledons, especially grasses (Poaceae), process of lignification is still unexplored in many of its aspects. Lignin deposition in cell wall is temporally and spatially specific and differs between species and tissues. The aim of this study was to investigate the dynamics of lignin synthesis and deposition, by using anatomical, physiological and molecular approach, in the stem of three spring barley cultivars (Hordeum vulgare L.) during four developmental stages: heading, anthesis, grain filling and ripening. Lignin localization and histochemical changes related to lignin deposition, total lignin content and gene expression of cinnamoyl CoA reductase (HvCCR) and cinnamyl alcohol dehydrogenase (HvCAD) was studied. Analyses showed that most of the lignin was deposited in the sclerenchyma ring in all three internodes. Total lignin content increased with stem development, especially in the first internodes and was the highest in ripening, but it was also relative to the cultivar and developmental stage. Genes of the lignin biosynthetic pathways HvCCR showed the highest expression in anthesis in the third internode of all three cultivars whereas gene HvCAD, in cultivars Astor and Scarlett, showed highest expression in anthesis and in cultivar Jaran in heading stage. Results obtained in this study will contribute to the comprehensive description of the biochemical and molecular changes that accompany lignin deposition in the cell wall during barley development.
