Abstract
Calcium oxalate CaOx crystals in higher plants occur in five forms raphides styloids prisms druses and crystal sand CaOx crystals are formed in almost all tissues in intravacuolar crystal chambers However the mechanism of crystallization and the role of CaOx crystals have not been clearly explained The aim of this study was to explore the occurrence and location of CaOx crystals in organs of Tinantia anomala Torr CB Clarke Commelinaceae with special attention to ultrastructural changes in the quantity of tapetal raphides during microsporogenesis We observed various parts of the plant that is stems leaves sepals petals anthers staminal trichomes and stigmatic papillae and identified CaOx crystals in all parts except staminal trichomes and stigmatic papillae in Tinantia anomala Three morphological forms styloids raphides and prisms were found in different amounts in different parts of the plant Furthermore in this species we identified tapetal raphides in anthers The number of tapetal raphides changed during microsporogenesis At the beginning of meiosis the biosynthesis of raphides proceeded intensively in the provacuoles These organelles were formed from the endoplasmic reticulum system In the tetrad stage we observed vacuoles with needleshaped raphides type I always localised in the centre of the organelle When the amoeboid tapetum was degenerating vacuoles also began to fade We observed a small number of raphides in the stage of mature pollen grainsThe author responsible for distribution of materials integral to the findings presented in this article in accordance with the policy described in the Instructions for Authors http//wwwplantcellorg Krystyna Winiarczyk krystynawiniarczykpocztaumcslublinpl
