“…After dehydration, the slides were sealed with neutral adhesive. Experimental procedures referred to previous studies (Hou, 2006a; Pereira et al, 2020; Paul & Chowdhury, 2021). Moreover, a comprehensive statistic of stomatal morphology was carried out, including stoma type, stoma aspect ratio, stoma density, and stoma index.…”

Previous phylogenetic analyses indicated that Polygonoideae, the largest subfamily in the Polygonaceae, is monophyletic. Phylogenetic relationships within the Polygonoideae have been substantially controversial. We collected 160 samples representing all currently recognized tribes for a more comprehensive phylogenetic analysis of the subfamily. Here, we reconstructed phylogenetic relationships of the Polygonoideae, inferred ancestral character states, and estimated the divergence time with a dense taxon sampling. This study corroborated and expanded previous results regarding the phylogenetic relationships of the Polygonoideae clade, and resolved the phylogenetic status of some controversial taxa by integrating molecular and morphological evidence. Phylogenetic analyses based on the complete plastomes suggested strong support for six primary clades that correspond to the most recent circumscription of tribes: Polygoneae, Rumiceae, Calligoneae, Pteroxygoneae, Fagopyreae, and Persicarieae. In addition, we provided further morphological data and assessed characters that supported different clades. The 3‐colpate pollen, 5‐parted perianth, and 3 styles were inferred to be the ancestral states of Polygonoideae. Divergence time estimation revealed that Polygonoideae originated around the late Cretaceous, and diversification was concentrated in the Eocene and Miocene. Time estimation indicated that the rapid uplift of the Tibetan Plateau and the intensification of the Asian monsoons might be potential driving forces for the diversification of Polygonoideae. Overall, this study advances our understanding of the phylogeny and diversification of the Polygonoideae and highlights the adaptive evolution of the taxa.

“…The determination of plant species with beekeeping importance was made through direct observations of bee foraging in the field and also based on the literature (Aguiar et al 2002;Pereira et al 2006;Santos et al 2006b;Vidal et al 2008;Marques et al 2011;Maia-Silva et al 2012;Nascimento et al 2014;Silva et al 2014b;Salis et al 2015;Salis et al 2017). Plant species with beekeeping importance were identified and grouped into a checklist with their respective floral resources (pollen/nectar/oil) identified based on the specialized literature (Pedro & Camargo 1991;Oliveira et al 1998;Aguiar et al 2002;Agostini & Sazima 2003;Aguiar et al 2003;Costa et al 2006;Machado & Lopes 2006;Pereira et al 2006;Santos et al 2006a;Santos et al 2006b;Viana et al 2006;Polatto et al 2007;Silva et al 2007;Vidal et al 2008;Mendonça et al 2008;Ramalho & Rosa 2010;Modro et al 2011;Moreira & Bragança 2011;Maia-Silva et al 2012;Nascimento et al 2014;Silva et al 2014a;Costa et al 2015;Salis et al 2015Salis et al , 2017Saturni et al 2015;Guimarães-Brasil et al 2017;Melo 2019;Pinto...…”

“…Nonetheless, for beekeepers to have an ideal use of quality and production of honey in a specific region, it is necessary to know the favourable flora for bees, besides analysing the soil, local climate, and support capacity of this region (Pereira et al 2006;Santos & Ribeiro 2009;Ribeiro et al 2019). Plants with beekeeping potential usually show intense flowering events, being attractive food sources for different species of bees.…”

“…The biological knowledge of plant species is important for beekeeping as flowering times, and pollen morphology helps to estimate the beekeeping potential of these species from the bee pasture and contribute to the creation of a flowering calendar for local bee plants (Freitas & Silva 2006;Lima et al 2006;Pereira et al 2006;Moreti et al 2007). Studies on the floristic diversity of interest to bees allow the creation of future strategies to rationally use the beekeeping flora and the conservation of their ecosystems, contributing to a possible production increase of honey (Mendonça et al 2008).…”

Floristic characterization and pollen morphology of plants visited by Apis mellifera L. in caatinga areas in Bahia, Brazil

et al. 2023

The aim of this study was to identify plant species visited by Apis mellifera L. in honey producing areas with typical Caatinga vegetation in the State of Bahia, as well as morphologically characterize pollen grains of the most representative species. Flowering specimens were collected from both areas, herborized, identified and deposited at the HUNEB herbarium. Analyses of floristic similarities were performed between eleven municipalities close to the study areas. Pollen was collected from all specimens, acetolyzed, measured, statistically analyzed, morphologically described, and photographed in light microscopy. Of the total of species recorded, 67.46 % were regarded as having beekeeping importance, with the richest botanical families being Fabaceae, Malvaceae and Asteraceae. Additionally, 37.5 % of the recorded species were herbs. The analyzed municipalities showed 84 % of floristic similarity. Of the total species recorded with visits by A. mellifera, 25.52 % had their pollen grains already described in the literature as monads, tetrads and polyads; isopolar, apolar and heteropolar; and mostly prolate spheroidal shape. Sizes varied from small to large, and the amb circular was predominant. The exine ornamentation was greatly diversified, varying from psilate to echinate. The obtained data corroborate the palynological knowledge of plants regarded as having beekeeping importance within the Caatinga.
