Última Chromosomal organization and phylogenetic relationships in Hypochaeris species (Asteraceae) from Brazil Genet. Mol. Biol. Ruas,Claudete de Fátima; Vanzela,André L.L.; Santos,Melissa O.; Fregonezi,Jeferson N.; Ruas,Paulo Maurício; Matzenbacher,Nelson I.; Aguiar-Perecin,Margarida L.R. de. The association of cytogenetic and molecular techniques has contributed to the analysis of chromosome organization and phylogeny in plants. The fluorochrome GC-specific CMA3, fluorescent in situ hybridization (FISH) and RAPD (Random Amplified Polymorphic DNA) markers were used to investigate chromosome structure and genetic relationships in Hypochaeris (Asteraceae). Seven species native to South America, and two species introduced from Europe (H. glabra and Hypochaeris sp) were studied. FISH with rDNA probes identified one or two loci of 18S-5.8S-25S rDNA in the South American Hypochaeris species and one locus in the European species. Only one 5S rDNA locus was seen in all species studied. Blocks of GC-rich heterochromatin (CMA-positive bands) associated...

Mol. Biol. Peng,Xiaojian; Wang,Qianqian; Zhao,Yang; Li,Xiaoyu; Ma,Qing. Abstract SPLs are plant-specific transcription factors that play important regulatory roles in plant growth and development. Systematic analysis of the SPL family has been performed in numerous plants, such as Arabidopsis, rice, and Populus. However, no comparative analysis has been performed across different species to examine evolutionary features. In this study, we present a comparative analysis of SPLs in different species. The results showed that 84 SPLs of the four species can be divided into six groups according to phylogeny. We found that most of the SPL-containing regions in maize showed extensive conservation with duplicated regions of rice and sorghum. A gene duplication analysis in maize indicated that ZmSPLs showed a significant excess of...
