Apomictic populations, which produce seeds with embryos without proper sexual syngamy, often show low genetic diversity, but eventually, such diversity has been reported to be surprisingly high. We studied here the in agamic complexes of Eriotheca crenulata (comb. n. E. gracilipes), pubescens (Malvaceae-Bombacoideae), and Handroanthus ochraceus (Bignoniaceae), tropical tree species from savannas Central Brazil. evaluated structure self-fertile polyploid sporophytic apomicts versus...
Plant stomata are essential structures (pores) that control the exchange of gases between plant leaves and atmosphere, also they influence adaptation to climate through photosynthesis transpiration stream. Many works in literature aim for a better understanding these their role evolution process behavior plants. Although studies dicots species have advanced considerably past years, even there is not much knowledge about cereal grasses. Due high morphological variation traits intra-...
Abstract Approximately 70% of the angiosperm species are polyploid, an important phenomenon in evolution those plants. But ploidy estimates have often been hindered because small size and large number chromosomes many tropical groups. Since polyploidy affects cell size, morphometric analyses pollen grains stomata used to infer level. Polyploidy is present Cerrado, Neotropical savanna region Central Brazil, has linked apomixis some taxa. Eriotheca gracilipes pubescens common tree this region,...
Abstract Research on stomata, i.e., morphological structures of plants, has increased in popularity the last years. These (pores) are charge interaction between internal plant system and environment, working different processes such as photosynthesis transpiration stream. Besides, a better understanding pore mechanism plays significant role when exploring evolution process, well behavior plants. Although study stomata dicots species plants advanced considerably past years, there is little...
Abstract Backgrounds and Aims Dimorphandra wilsonii Rizzini, a critically endangered protected tree, has restricted distribution in the ecotone between Cerrado Atlantic Forest south-eastern Brazil. In this area, it co-occurs with D. mollis Benth., common tree from Cerrado, exaltata Schott., rare Forest. Previous studies of indicated heterozygosity excess at individual level. Field observation some intermediate phenotypes both congeners suggests hybridization and/or exaltata. Here, we tested...
Polyploidy and whole genome duplication are major evolutionary drivers in plants. Climate variations during the Pleistocene have influenced distribution range expansion worldwide. Similar trends been reported for Cerrado plants, but no attempt has made to link phylogeography with ploidy breeding changes. Thus, we aimed (i) assess size of Eriotheca estevesiae Carv.-Sobr., compare it E. pubescens (Mart.) Schott & Endl. (Both included into Stellate Trichome Species Complex - ESTSC). (ii)...
The cultivation of species in urban areas for landscaping or consumption has increased cities surrounded by Cerrado, putting risk the local flora.Thus, objective this paper was to describe seed germination and seedling emergence five cultivated Melastomataceae Bombacoideae compare them with Cerrado native evaluate if they offer any vegetation.The seeds were collected area Uberlândia, within Brazilian Cerrado.We calculated measurements compared literature data.Seeds
Abstract Apomixis is the asexual production of seeds by plants and, in theory, would render low genetic diversity and even clonal lineages. However, recent studies have shown otherwise, although not always clear where obligate apomicts comes from. We evaluated among sister seedlings M. albicans , an apomictic species Cerrado, Neotropical Savannas Central Brazil. A total 50 from five individuals were analysed using ISSR primers. obtained 107 fragments, all with good resolution, consistently...
We describe a new species endemic to the Cerrado province from state of Minas Gerais: Eriotheca luzensis (Malvaceae, Bombacoideae). This can be identified by its yellow pubescent indumentum associated with ferruginous scales, mainly grouped in calyx apex. provide diagnosis, complete description, taxonomic comments, key differentiate E. congeners Gerais, plate diagnostic features, distribution map, and preliminary conservation status. also included notes on reproductive system information...
Abstract Geographic parthenogenesis, range expansion of apomictic plants after climate changes, has been described for Northern Hemisphere gametophytic apomicts. But similar trends have observed sporophytic apomicts Cerrado, the savannas in Brazil. Eriotheca pubescens is a common Cerrado tree, an agamic complex either hexaploid/polyembryonic or tetraploid/monoembryonic sexual individuals. Some populations as new species, estevesiae , all included Stellate Trichome Species Complex (ESTSC)....
Abstract Hybridization and changes in ploidy have been associated with shifts from sexuality to apomixis, may explain isolation among populations species. Hybrids resulting interploidy crosses contribute a broader understanding of how these species originated evolved. Stomatal morphometrics flow cytometry analyses were carried out for seedlings different Eriotheca estevesiae, E. gracilipes pubescens, group closely related tree the Central Brazilian Cerrados. Controlled cross-pollinations...
