Saururus chinensis is a core member of Saururaceae, a perianthless (lacking petals or sepals) family. Due to its basal phylogenetic position and unusual floral composition, study of this plant family is important for understanding the origin and evolution of perianthless flowers and petaloid bracts among angiosperm species. To isolate genes involved in S. chinensis flower development, subtracted floral cDNA libraries were constructed by using suppression subtractive hybridization (SSH) on… Expand
The role of ABC genes in shaping perianth phenotype in the basal angiosperm Magnolia.
Magnolia genus is capable of forming, in some species, a perianth differentiated into a calyx (sepals) and corolla (petals), even though no clear gradient of morphological changes could be observed. Expand
Identification of a novel homolog for a calmodulin-binding protein that is upregulated in alloplasmic wheat showing pistillody
Wheat Calmodulin-Binding Protein 1 plays a role in formation and development of pistil-like stamens induced by mitochondrial retrograde signaling, indicating that it was associated with spikelet/floret development. Expand
Dynamic expression analysis of early response genes induced by potato virus Y in PVY-resistant Nicotiana tabacum
Key messageDynamic transcriptional changes of the host early responses genes were detected in PVY-resistant tobacco varieties infected with Potato virus Y; PVY resistance is a complex process thatExpand


Extended expression of B-class MADS-box genes in the paleoherb Asarum caudigerum
Remarkably, APETALA3 (AP3) B-class genes isolated from A. caudigerum were upregulated in the perianth, stamens and carpels, implying that the expression domain of B- class genes in this basal angiosperm was broader than those in their eudicot counterparts. Expand
Expressed sequence tags (ESTs) and phylogenetic analysis of floral genes from a paleoherb species, Asarum caudigerum.
The origin of A. caudigerum is intermediate between the angiosperms and gymnosperms, and phylogenetic trees were reconstructed in order to infer evolutionary relationships within the MADS-box gene family. Expand
Characterization of MADS genes in the gymnosperm Gnetum parvifolium and its implication on the evolution of reproductive organs in seed plants
It is suggested that the comparable reproductive organs in Gnetum and flowering plants evolved in parallel, and is likely to support the homology between the ovule‐ovuliferous scale complex of conifers and the G Netum ovules, including the three envelopes. Expand
Floral MADS box genes and homeotic gender dimorphism in Thalictrum dioicum (Ranunculaceae) - a new model for the study of dioecy.
The potential of T. dioicum as a new model for the study of sex determination in the basal eudicots is discussed, raising the possibility that genetic mechanisms working at or above the level of organ identity promote sex determination through a homeotic-like mechanism. Expand
Evolution of the Petal and Stamen Developmental Programs: Evidence from Comparative Studies of the Lower Eudicots and Basal Angiosperms
These findings indicate that although some aspects of the ABC program are conserved, others display a high degree of plasticity and may not have become fixed until later in angiosperm evolution. Expand
Elaboration of B Gene Function to Include the Identity of Novel Floral Organs in the Lower Eudicot Aquilegia[W]
The findings show that preexisting floral organ identity programs can be partitioned and modified to produce additional organ types, and indicate that some types of petaloid organs are not entirely dependent on AP3/PI homologs for their identity. Expand
Heterotopic expression of class B floral homeotic genes supports a modified ABC model for tulip (Tulipa gesneriana)
Northern hybridization analysis showed that all of these genes are expressed in whorls 1, 2 and 3 (outer and inner tepals and stamens), thus corroborating the modified ABC model, and cloned and characterized putative class B genes from tulip, confirming this phenomenon is conserved within Liliaceae plants or even monocot species.

Are petals sterile stamens or bracts? The origin and evolution of petals in the core eudicots.
The origin and evolution of petals appears to be as complex on a molecular basis as it is from a morphological point of view. Expand
Evolution of the APETALA3 and PISTILLATA lineages of MADS-box-containing genes in the basal angiosperms.
Comparison of genomic structure among PI homologs indicates that a 12-nucleotide deletion that had been considered synapomorphic for the whole PI lineage actually arose within the ANITA grade, after the split of the Nymphaeales but before the separation of the Austrobaileyales. Expand
APETALA3 and PISTILLATA homologs exhibit novel expression patterns in the unique perianth of Aristolochia (Aristolochiaceae)
The expression of AP3 and PI homologs in the perianth does not suggest a role in organ identity but, rather, in promoting late aspects of cell differentiation, implications for the evolution of both petaloidy and B gene function are discussed. Expand
