Diverse Mesozoic thrips carrying pollen during the gymnosperm-to-angiosperm plant-host ecological shift [PDF]
iScienceSummary: Insects are important pollinators, and entomophilous pollination of gymnosperms occurred long before the Cretaceous radiation of angiosperms, but most extant pollination systems involve angiosperms.

The Douglas-Fir Genome Sequence Reveals Specialization of the Photosynthetic Apparatus in Pinaceae [PDF]
G3: Genes, Genomes, Genetics, 2017 A reference genome sequence for Pseudotsuga menziesii var. menziesii (Mirb.) Franco (Coastal Douglas-fir) is reported, thus providing a reference sequence for a third genus of the family Pinaceae.

Gymnosperm Resprouting—A Review [PDF]
Plants, 2021 Gymnosperms are generally regarded as poor resprouters, especially when compared to angiosperms and particularly following major disturbance. However, is it this clear-cut?

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

Phylogenomic Inference Suggests Differential Deep Time Phylogenetic Signals from Nuclear and Organellar Genomes in Gymnosperms [PDF]
PlantsThe living gymnosperms include about 1200 species in five major groups: cycads, ginkgo, gnetophytes, Pinaceae (conifers I), and cupressophytes (conifers II).

Tissue-specific transposon-associated small RNAs in the gymnosperm tree, Norway spruce [PDF]
BMC Genomics, 2019 Background Small RNAs (sRNAs) are regulatory molecules impacting on gene expression and transposon activity. MicroRNAs (miRNAs) are responsible for tissue-specific and environmentally-induced gene repression.

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

Spatiotemporal Distribution Patterns and Conservation Priorities of Gymnosperms With Different Leaf Shapes in China Under Climate Change [PDF]
Ecology and EvolutionLeaf morphology is one of the important indicators for studying the response of plants to climate change. Gymnosperms play a crucial role in maintaining biodiversity and ecosystem stability in China. However, the geographical and altitudinal distribution

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