Cytokinin Biosynthesis in Mutants of the Moss Physcomitrella patens.
نویسندگان
چکیده
Three cytokinin-over-producing mutants of the moss, Physcomitrella patens, have been shown to convert [8-(14)C]adenine to N(6)-[(14)C](Delta(2)-isopentenyl)adenine, the presence of which was confirmed by thin layer chromatography, high performance liquid chromatography, and recrystallization to constant specific radioactivity. The labeled cytokinin was detected in the culture medium within 6 hours and the tissue itself appears to contain both labeled N(6)-(Delta(2)-isopentenyl)adenine and N(6)-(Delta(2)-isopentenyl)adenosine monophosphate.

Cytokinins from the Moss Physcomitrella patens.
Gametophore-over-producing mutants of the moss, Physcomitrella patens, when grown in liquid culture export high levels of cytokinin into their culture medium. The cytokinin produced by these mutants is postulated to account for their peculiar phenotype, that of mosses treated with exogenous cytokinin. N(6)-(Delta(2)-isopentenyl)adenine, the major cytokinin, has been identified previously in two...
متن کاملCHASE domain-containing receptors play an essential role in the cytokinin response of the moss Physcomitrella patens
While the molecular basis for cytokinin action is quite well understood in flowering plants, little is known about the cytokinin signal transduction in early diverging land plants. The genome of the bryophyte Physcomitrella patens (Hedw.) B.S. encodes three classical cytokinin receptors, the CHASE domain-containing histidine kinases, CHK1, CHK2, and CHK3. In a complementation assay with protopl...
متن کاملIsopentenyltransferase-1 (IPT1) knockout in Physcomitrella together with phylogenetic analyses of IPTs provide insights into evolution of plant cytokinin biosynthesis
The moss Physcomitrella patens is part of an early divergent clade of land plants utilizing the plant hormone cytokinin for growth control. The rate-limiting step of cytokinin biosynthesis is mediated by isopentenyltransferases (IPTs), found in land plants either as adenylate-IPTs or as tRNA-IPTs. Although a dominant part of cytokinins in flowering plants are synthesized by adenylate-IPTs, the ...

Stem cells self-renew and repeatedly produce differentiated cells during development and growth. The differentiated cells can be converted into stem cells in some metazoans and land plants with appropriate treatments. After leaves of the moss Physcomitrella patens are excised, leaf cells reenter the cell cycle and commence tip growth, which is characteristic of stem cells called chloronema apic...
