De novo Assembly and Comparative Analyses of Mitochondrial Genomes in Piperales. [PDF]
Genome Biology and Evolution, 2023 AbstractThe mitochondrial genome of Liriodendron tulipifera exhibits many ancestral angiosperm features and a remarkably slow evolutionary rate, while mitochondrial genomes of other magnoliids remain yet to be characterized. We assembled nine new mitochondrial genomes, representing all genera of perianth-bearing Piperales, as well as for a member of ...

Evolution of the Subgroup 6 R2R3-MYB Genes and Their Contribution to Floral Color in the Perianth-Bearing Piperales [PDF]
Frontiers in Plant Science, 2021 Flavonoids, carotenoids, betalains, and chlorophylls are the plant pigments responsible for floral color. Anthocyanins, a class of flavonoids, are largely responsible for the red, purple, pink, and blue colors. R2R3-MYB genes belonging to subgroup 6 (SG6)

Flower development and perianth identity candidate genes in the basal angiosperm Aristolochia fimbriata (Piperales: Aristolochiaceae) [PDF]
Frontiers in Plant Science, 2015 Aristolochia fimbriata (Aristolochiaceae: Piperales) exhibits highly synorganized flowers with a single convoluted structure forming a petaloid perianth that surrounds the gynostemium, putatively formed by the congenital fusion between stamens and the ...

Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic). [PDF]
New PhytolMorphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]
Plant Environ InteractExponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Diverging repeatomes in holoparasitic Hydnoraceae uncover a playground of genome evolution. [PDF]
New PhytolSummary The transition from an autotrophic to a heterotrophic lifestyle is associated with numerous genomic changes. These often involve large genomic alterations, potentially driven by repetitive DNAs. Despite their recognized role in shaping plant genomes, the contribution of repetitive DNAs to parasitic plant genome evolution remains largely ...
