Yu.V. Venzhik, V.V. Talanova, A.F. Titov, E.A. Miroslavov. The ultrastructure of chloroplasts in wheat during cold adaptation and aba influence // Transactions of Karelian Research Centre of Russian Academy of Science. No 5. Experimental biology. 2014. Pp. 102-107
Keywords: Triticum aestivum L., cold hardening, abscisic acid, cold tolerance, ultrastructure of chloroplasts.
The study of wheat seedlings showed that exogenous abscisic acid (ABA) not only stimulated an additional increase of the leaf cells cold tolerance in the process of cold adaptation (4 °C) but also modified the ultrastructure of chloroplasts. In particular, the results gained during wheat hardening with exogenous ABA (0.1 mM ) indicated an additional increase in the area and density of the chloroplasts stroma, formation of numerous invaginations in chloroplasts as well as changes in the plastids thylakoid system. It seems that most of the observed ultrastructural changes in chloroplasts are involved in the formation of an increased leaf cells tolerance and meant to “fix” and support a certain part of functional changes, promoting thereby the longterm cold tolerance of the plants.
