Abstract Physalis (75+ species, Solanaceae) is most diverse in Mexico, with only the type, P. alkekengi, native to the Old World. Interspecific relationships are poorly known, and despite the distinctive inflated fruiting calyces, generic limits remain uncertain. Sequence data from part of the nuclear gene waxy (622 bp) and the internal transcribed spacer of the nrDNA (652 bp) were used to generate a phylogeny of subtribe Physalinae. Thirty-five species of Physalis and eight physaloid genera… Expand
Complete chloroplast genomes of four Physalis species (Solanaceae): lights into genome structure, comparative analysis, and phylogenetic relationships
TLDR
The results enrich the data on the cp genomes of the genus Physalis, with Physalis in the middle and upper part of the phylogenetic tree, with a monophyletic evolution having a 100% bootstrap value. Expand
The generic position of two species of tribe Physaleae(Solanaceae) inferred from three DNA sequences: A case study on Physaliastrum and Archiphysalis
Abstract For the first time, samples of Physaliastrum and Archiphysalis are included in a molecular phylogenetic analysis of the tribe Physaleae based on the plastid loci ndhF and trnL-F and theExpand
Physalis and physaloids: A recent and complex evolutionary history.
TLDR
Recent origin, high diversification, and morphological complexity have contributed, at least with the currently available methods, to the inability to completely disentangle the phylogenetic relationships of Physalinae. Expand
Karyotype asymmetry shapes diversity within the physaloids (Physalidinae, Physalideae, Solanaceae)
TLDR
Overall, this study suggests that Physalidineae diversification has been accompanied by karyotype changes, which can be applied to delimit genera within the group. Expand
Karyotype asymmetry shapes diversity within the physaloids (Physalidinae, Physalideae, Solanaceae)
TLDR
This study suggests that diversification in this group has been accompanied by karyotype changes, which can also be applied to delimit genera, as well as differentiate genera within subtribe Physalidinae. Expand
A new combination in Alkekengi (Solanaceae) for the Flora of China
TLDR
In order to emphasize the monophyly and morphological homogeneity of the New World species and decrease nomenclatural disruption, the genus Physalis was proposed for conservation with a conserved type, P. pubescens Linneaus, to represent the NewWorld species (Whitson 2011). Expand
Molecular identification of species of Physalis (Solanaceae) using a candidate DNA barcode: the chloroplast psbA-trnH intergenic region.
TLDR
Results of both BLAST1 and nearest-distance methods prove that the psbA-trnH regions can be used as an efficient DNA barcode for the identification of species of Physalis and confirm the relationship between species and closely related species. Expand
Nomenclatural Innovations in North American Physalis (Solanaceae)
TLDR
The type specimen is from northern Florida and exhibits characters that are intermediate between the two parents, most notably narrowly ovate to lanceolate leaves and a sparse dendriticstellate pubescence throughout. Expand
A molecular phylogeny of the Solanaceae
TLDR
The current results corroborate previous studies that identify a monophyletic subfamily Solanoideae and the more inclusive "x = 12" clade, which includes Nicotiana and the Australian tribe Anthocercideae, and provide greater resolution among lineages within Solanoidesae. Expand
Evolution of the inflated calyx syndrome in Solanaceae.
TLDR
Surprisingly, expression of MPF2-like genes in floral organs appears to be plesiomorphic in both the Physaleae and the Capsiceae, raising the possibility that originally ICS also was actually a plesiomorph character in these 2 groups. Expand

Testa Patterns in Some Species of Physalis L. and Some Other Genera in the Tribe Solaneae (Solanaceae)

TLDR
Testa patterns in Physalis, Chamaesaracha and Jaborosa showed unique "wings" on the testa that originated from different heights of the anticlinal walls, a character apparently unique to Physalis and the closely related Margaranthus. Expand
