Gymnosperm Resprouting—A Review [PDF]

open access: yesPlants, 2021
Gymnosperms are generally regarded as poor resprouters, especially when compared to angiosperms and particularly following major disturbance. However, is it this clear-cut?

Diverse Mesozoic thrips carrying pollen during the gymnosperm-to-angiosperm plant-host ecological shift [PDF]

open access: yesiScience
Summary: Insects are important pollinators, and entomophilous pollination of gymnosperms occurred long before the Cretaceous radiation of angiosperms, but most extant pollination systems involve angiosperms.

Construction of Ancestral Chromosomes in Gymnosperms and the Application in Comparative Genomic Analysis [PDF]

open access: yesPlants
Chromosome rearrangements during plant evolution can lead to alterations in genome structure and gene function, thereby influencing species adaptation and evolutionary processes.

Seed Wings Optimize the Regulation of Temperature and Light on Smith Fir Seed Germination Timing [PDF]

open access: yesPlants
Seed wings are widely recognized for facilitating dispersal and influencing germination in angiosperms, but their functional role in gymnosperm germination is poorly understood.

Developmentally regulated genes drive phylogenomic splits in ovule evolution [PDF]

open access: yesNature Communications
The evolution of seeds transformed life on earth and is responsible for our most important food crops. Gymnosperms, the oldest living seed plants, are an untapped genomic reservoir for genes involved in seed evolution.

Phylogenomic Inference Suggests Differential Deep Time Phylogenetic Signals from Nuclear and Organellar Genomes in Gymnosperms [PDF]

open access: yesPlants
The living gymnosperms include about 1200 species in five major groups: cycads, ginkgo, gnetophytes, Pinaceae (conifers I), and cupressophytes (conifers II).

Lingyuanfructus: The First Fossil Angiosperm with Naked Seeds [PDF]

open access: yesLife
Unlike gymnosperms with naked ovules, angiosperms are defined and characterized by their enclosed ovules. According to plant evolution theories, angiosperms should be derived from their gymnospermous ancestors, which have naked ovules.

PtABI3 represses the age biomarker gene PtDAL1 during male cone development in conifer [PDF]

open access: yesForestry Research
The age biomarker gene PtDAL1 in conifers undergoes expression resetting during pollen maturation, but its regulatory mechanisms remain unclear. This study identifies PtABI3, a B3 transcription factor (TF) in Pinus tabuliformis, as a key repressor of ...

Competition and Niche Differentiation of Water and Nutrients between Broussonetia papyrifera and Platycladus orientalis under Prolonged Drought Stress

open access: yesAgronomy, 2022
Little is known about the competition between and niche differentiation of water and nutrients between angiosperm and gymnosperm tree species under prolonged drought stress, especially in fragile environments.

miR160 Interacts in vivo With Pinus pinaster AUXIN RESPONSE FACTOR 18 Target Site and Negatively Regulates Its Expression During Conifer Somatic Embryo Development

open access: yesFrontiers in Plant Science, 2022
MicroRNAs (miRNAs) are key regulators of several plant developmental processes including embryogenesis. Most miRNA families are conserved across major groups of plant species, but their regulatory roles have been studied mainly in model species like ...
