The major clades of MADS-box genes and their role in the development and evolution of flowering plants.
TLDR
The deep branching of the MADS-box gene tree is described to place the MIKC(c)-type genes into an evolutionary context and reveal that the diversity of MADs-box genes in Arabidopsis is rather ancient and representative for other flowering plants. Expand
The Norway spruce genome sequence and conifer genome evolution
TLDR
The draft assembly of the 20-gigabase genome of Norway spruce (Picea abies), the first available for any gymnosperm, is presented, revealing numerous long (>10,000 base pairs) introns, gene-like fragments, uncharacterized long non-coding RNAs and short RNAs, which opens up new genomic avenues for conifer forestry and breeding. Expand
A short history of MADS-box genes in plants
TLDR
It is demonstrated that the phylogeny of MADS-box genes was strongly correlated with the origin and evolution of plant reproductive structures such as ovules and flowers, and it seems likely that changes in MADs-box gene structure, expression and function have been a major cause for innovations in reproductive development during land plant evolution. Expand
MIKC-type MADS-domain proteins: structural modularity, protein interactions and network evolution in land plants.
TLDR
It is hypothesize that combinatorial multimer formation of MIKC-type MADS-domain proteins facilitated an unusually efficient and rapid functional diversification based on gene duplication, sequence divergence and fixation. Expand
The Selaginella Genome Identifies Genetic Changes Associated with the Evolution of Vascular Plants
TLDR
The genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported, is reported, finding that the transition from a gametophytes- to a sporophyte-dominated life cycle required far fewer new genes than the Transition from a non Seed vascular to a flowering plant. Expand
Heterotopic expression of class B floral homeotic genes supports a modified ABC model for tulip (Tulipa gesneriana)
TLDR
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. Expand
MADS-box genes reveal that gnetophytes are more closely related to conifers than to flowering plants.
TLDR
P phylogeny reconstructions and the outcome of expression studies suggest that complex features such as flower-like reproductive structures and double-fertilization arose independently in gnetophytes and angiosperms. Expand
Functional conservation and diversification of class E floral homeotic genes in rice (Oryza sativa).
TLDR
These findings reveal conservation of SEP-like genes in specifying floral determinacy and organ identities since the separation of eudicots and monocots about 150 million years ago, however, they indicate also monocot-specific neo- and sub-functionalization events and hence underscore the evolutionary dynamics ofSEP- like genes. Expand
Two ancient classes of MIKC-type MADS-box genes are present in the moss Physcomitrella patens.
TLDR
The studies reveal an ancient duplication of an MIKC-type gene that occurred before the separation of the lineages that led to extant mosses and vascular plants more than about 450 MYA, and strongly suggest that the most recent common ancestor of mossesand vascular plants contained at least one MI KC(c)-type and one MIKC(*)-type gene. Expand
Structural diversification and neo-functionalization during floral MADS-box gene evolution by C-terminal frameshift mutations.
TLDR
Data is presented suggesting that frameshift mutations in the C-terminal domain of specific ancestral MADs-box genes may have contributed to the structural and functional divergence of the MADS-box gene family. Expand
