Stimulatory and Inhibitory Conditioning Factors that Regulate Cell Proliferation and Morphogenesis in Plant Cell Cultures

Proliferation and morphogenesis in plant cell cultures are influenced by the conditioning factors that are produced by the cultured cells themselves. Phytosulfokines(PSKs), sulfated peptide growth factors, have been identified as conditioning factors that promote cell proliferation in plant cell cultures. Our research has shown that the formation of carrot somatic embryos is regulated by both stimulatory and inhibitory conditioning factors. The stimulatory factor was found to be PSK, which markedly increased the frequency of somatic embryo formation. In contrast, the inhibitory factor was identified as 4-hydroxybenzyl alcohol(4HBA). 4HBA strongly inhibited somatic embryo formation by specifically suppressing the rapid cell division that is characteristic of the early globular stage. These findings suggest that dose-balancing of various plant growth regulators, including PSK and inhibitory factors, like 4HBA, might contribute to cell proliferation and morphogenesis in plant cell cultures.
