Complete plastid genomes from Ophioglossum californicum, Psilotum nudum, and Equisetum hyemale reveal an ancestral land plant genome structure and resolve the position of Equisetales among monilophytes [PDF]

open access: yesBMC Evolutionary Biology, 2013
Background Plastid genome structure and content is remarkably conserved in land plants. This widespread conservation has facilitated taxon-rich phylogenetic analyses that have resolved organismal relationships among many land plant groups.

Structural Variation of Plastomes Provides Key Insight Into the Deep Phylogeny of Ferns [PDF]

open access: yesFrontiers in Plant Science, 2022
Structural variation of plastid genomes (plastomes), particularly large inversions and gene losses, can provide key evidence for the deep phylogeny of plants.

Evolution and expression of LEAFY genes in ferns and lycophytes [PDF]

open access: yesEvoDevo, 2022
Background The LEAFY (LFY) transcription factors are present in algae and across land plants. The available expression and functional data of these genes in embryophytes suggest that LFY genes control a plethora of processes including the first zygotic ...

Diversity and host plant utilization of leaf-mining beetles of Chrysomeloidea (Coleoptera) in Japan [PDF]

open access: yesZooKeys
The superfamily Chrysomeloidea (Cerambycidae + Chrysomelidae + Megalopodidae) encompasses a diverse phytophagous beetles, whose larvae exhibit internal or external feeding on leaves, wood, or roots of many plants.

Origin of horsetails and the role of whole-genome duplication in plant macroevolution. [PDF]

open access: yesProc Biol Sci, 2019
Whole-genome duplication (WGD) has occurred commonly in land plant evolution and it is often invoked as a causal agent in diversification, phenotypic and developmental innovation, as well as conferring extinction resistance.

First record of late Devonian-early Carboniferous palynoflora from the Lipak Formation, Spiti Basin, Tethyan Himalaya, India, and their biostratigraphic implications

open access: yesJournal of the Palaeontological Society of India, 2023
The present work elucidates palynofloral records from the Lipak Formation (late Devonian– early Carboniferous) of the Spiti Basin. The study has been carried out from three different sections of Spiti and Pin valleys to look for the signatures of ...

Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content. [PDF]

open access: yes, 2016
Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced rate of nucleotide substitution ...
