The moss Physcomitrella patens is part of an early divergent clade land plants utilizing the plant hormone cytokinin for growth control. rate-limiting step biosynthesis mediated by isopentenyltransferases (IPTs), found in either as adenylate-IPTs or tRNA-IPTs. Although a dominant cytokinins flowering are synthesized adenylate-IPTs, genome only encodes homologues This study therefore looked into question whether derive from tRNA exclusively. Targeted gene knockout ipt1 (d|ipt1) along with...
Plants make use of “two-component systems” ([TCS][1]s) for signal transduction, and these are involved in a number vital cellular responses, such as responses to cytokinins, ethylene, red light, osmosensing ([Schaller et al., 2011][2]). The [TCS][1] found plants incorporates three
While the molecular basis for cytokinin action is quite well understood in flowering plants, little known about signal transduction early diverging land plants. The genome of bryophyte Physcomitrella patens (Hedw.) B.S. encodes three classical receptors, CHASE domain-containing histidine kinases, CHK1, CHK2, and CHK3. In a complementation assay with protoplasts receptor-deficient Arabidopsis thaliana as binding assays, we found evidence that CHK1 CHK2 receptors can function perception. Using...
Abstract Sexual reproduction in angiosperms requires the production and delivery of two male gametes by a three-celled haploid gametophyte. This demands synchronized gene expression short developmental window to ensure double fertilization seed set. While transcriptomic changes developing pollen are known for Arabidopsis , no studies have integrated RNA proteomic data this model. Further, role alternative splicing has not been fully addressed, yet post-transcriptional post-translational...
Abstract The evolution of plant organs, including leaves, stems, roots, and flowers, mediated the explosive radiation land plants, which shaped biosphere allowed establishment terrestrial animal life. Furthermore, fertilization products angiosperms, seeds serve as basis for most our food. organs immobile gametes required coordinated acquisition novel gene functions, co-option existing genes, development regulatory programs. However, knowledge these events is limited, no large-scale analyses...
