Molecular Systematics of Plants
TL;DR: The chloroplast DNA restriction site variation and the evolution of the annual habit in North American Coreopsis (Asteraceae) and the suitability of molecular and morphological evidence in reconstructing plant phylogeny are examined.

Secondary sex characters in plants
David G. Lloyd,C. J. Webb +1 more
TL;DR: The benefits to males of increasing pollen production and to females of increasing ovule production differ in such a way that the optimal reproductive effort will often be less for males than for females; this appears to explain a number of secondary sex characters.
Journal ArticleDOI
Advances in the study of polyploidy since Plant speciation
TL;DR: Despite the recent advances in the understanding of polyploid evolution, many exciting aspects remain under-investigated, and some of these include the consequences of genetic and genomic changes in naturalpolyploid populations, the physiological and ecological effects of polyPLoidy, and whether recurrent polyploidsy prompts evolution to repeat itself.
Journal ArticleDOI
Widespread genome duplications throughout the history of flowering plants

TL;DR: Cross-species sequence divergence estimates suggest that synonymous substitution rates in the basal angiosperms are less than half those previously reported for core eudicots and members of Poaceae, and lower substitution rates permit inference of older duplication events.
Journal ArticleDOI
Crossover/noncrossover differentiation, synaptonemal complex formation, and regulatory surveillance at the leptotene/zygotene transition of meiosis.
TL;DR: During wild-type meiosis, recombinational interactions are differentiated into CR and NCR types very early, prior to onset of stable strand exchange and independent of SC, suggesting that SC formation may require interference.
