Synthesis and hydrolysis of conjugates of plant hormones in regulating the level of active hormones

Plant hormones are important in all aspects of plant growth and development , but the phenomenon of hormonal homeostasis is not fully understood. Conjugation of phytohormones is considered an important element of the mechanism responsible for the levels of these compounds in the cell. It is a process that occurs in all tested plants in response to environmental and physiological factors .

Changes in ultrastructure and distribution of plasmodesmata and the process of differentiation for example anterydiostanów algae of the genus Chara

Describes the changes in the structure and distribution of plasmodesmata during the development of C. vulgaris anterydiostanów and C. tomentosa since the creation of the 24-cell germ to form mature spermatozoidów. These changes are associated with well-defined stages of differentiation, and may provide for adjustment of the structure and function of plasmodesmata in intercellular communication to the changing situation morphogenetic. It has been suggested that regulatory mechanisms symplastycznej the development and operation of the plant are universal.
