Phylogenetic relationships in Solanaceae and related species based on cpDNA sequence from plastid trnE-trnT region [PDF]

, 2008
Intergenic spacers of chloroplast DNA (cpDNA) are very useful in phylogenetic and population genetic studies of plant species, to study their potential integration in phylogenetic analysis. The non-coding trnE-trnT intergenic spacer of cpDNA was analyzed

The bumble bees (Hymenoptera: Apidae: Bombus) of Arkansas, fifty years later [PDF]

, 2015
Many species of bumble bees (Hymenoptera: Apidae: Bombus Latreille) are declining throughout their ranges in North America, yet detecting population trends can be difficult when historical survey data are lacking.  In the present study, contemporary data

Pollen morphology of Plantago species native to Poland and their taxonomic implications

Acta Societatis Botanicorum Poloniae, 2011
Pollen grains of 9 species of the genus Plantago (Plantaginaceae), including 8 taxa native to Poland, were observed under a light microscope and a scanning electron microscope. Descriptions of grain sculpture are illustrated only SEM micrographs.

Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

Assembly of Australia's Alpine Seed Plant Flora

Austral Ecology, Volume 51, Issue 4, April 2026.
ABSTRACT To characterise the assembly of Australia's distinctive native alpine seed plant flora. Past events when species were sequestered into the alpine habitat from warmer climates and/or distant regions were identified using published phylogenies and distribution information.

Several plant self‐incompatibility systems may be controlled by atypical receptor–ligand interactions

The Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Self‐incompatibility (SI) is the single most important mechanism utilized by flowering plants to avoid self‐fertilization, thus preventing inbreeding and promoting outcrossing. Many plant SI systems are genetically controlled by a multi‐allelic S‐locus, containing two tightly linked genes that encode the female and male S‐determinants.
