The complete chloroplast genome of Myriophyllum spicatum reveals a 4‐kb inversion and new insights regarding plastome evolution in Haloragaceae

open access: yesEcology and Evolution, 2020
Myriophyllum, among the most species‐rich genera of aquatic angiosperms with ca. 68 species, is an extensively distributed hydrophyte lineage in the cosmopolitan family Haloragaceae. The chloroplast (cp) genome is useful in the study of genetic evolution,

Explosive Radiation of Malpighiales Supports a Mid-Cretaceous Origin of Modern Tropical Rain Forests [PDF]

open access: yes, 2005
Fossil data have been interpreted as indicating that Late Cretaceous tropical forests were open and dry adapted and that modern closed-canopy rain forest did not originate until after the Cretaceous-Tertiary (K/T) boundary.

Assembled Plastid and Mitochondrial Genomes, as well as Nuclear Genes, Place the Parasite Family Cynomoriaceae in the Saxifragales [PDF]

open access: yesGenome Biology and Evolution, 2016
Cynomoriaceae, one of the last unplaced families of flowering plants, comprise one or two species or subspecies of root parasites that occur from the Mediterranean to the Gobi Desert. Using Illumina sequencing, we assembled the mitochondrial and plastid genomes as well as some nuclear genes of a Cynomorium specimen from Italy.

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]

open access: yes, 2016
Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

First whole genome sequence of a diploid crop wild relative of the Andean tuber “oca”: Annotation and comparative genomic analysis of Oxalis oulophora

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Oxalis oulophora, a diploid species closely related to the octoploid Andean tuber crop oca (Oxalis tuberosa), was selected for whole‐genome sequencing to aid in understanding the origins of polyploidy and domestication in oca and its relatives (crop wild relatives).
