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.

Functional and morphological evolution in gymnosperms: A portrait of implicated gene families
Evolutionary Applications, 2020 Gymnosperms diverged from their sister plant clade of flowering plants 300 Mya. Morphological and functional divergence between the two major seed plant clades involved significant changes in their reproductive biology, water‐conducting systems ...

Phylogeny and Divergence Times of Gymnosperms Inferred from Single-Copy Nuclear Genes [PDF]
PLoS ONE, 2014 Phylogenetic reconstruction is fundamental to study evolutionary biology and historical biogeography. However, there was not a molecular phylogeny of gymnosperms represented by extensive sampling at the genus level, and most published phylogenies of this

Evolutionary Analysis of MIKCc-Type MADS-Box Genes in Gymnosperms and Angiosperms
Frontiers in Plant Science, 2017 MIKCc-type MADS-box genes encode transcription factors that control floral organ morphogenesis and flowering time in flowering plants. Here, in order to determine when the subfamilies of MIKCc originated and their early evolutionary trajectory, we ...

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

The Systematics and Evolution of Gymnosperms with an Emphasis on a Few Problematic Taxa
PlantsGymnosperms originated in the Middle Devonian and have experienced a long evolutionary history with pulses of speciation and extinction, which resulted in the four morphologically distinct extant groups, i.e., cycads, Ginkgo, conifers and gnetophytes ...

Pollen Germination and Pollen Tube Growth in Gymnosperms
Plants, 2021 Pollen germination and pollen tube growth are common to all seed plants, but these processes first developed in gymnosperms and still serve for their successful sexual reproduction.

The Role of Plant Evolutionary History in Shaping the Variation in Specific Leaf Area Across China [PDF]
Ecology and EvolutionSpecific leaf area (SLA, leaf area per unit leaf dry mass) occupies a central position in both community assembly and ecosystem functioning. Although SLA has significant phylogenetic signals, how and to what extent the evolutionary history influences the

The age-related expression patterns of Larix kaempferi AP2 subfamily genes and functional dissection of LkTOE1-2 in seed formation and germination [PDF]
Forestry ResearchConifers pose challenges for breeding programs due to their extended vegetative phases. Despite the critical role of APETALA2 (AP2) in regulating phase transitions, the AP2/ERF superfamily remains largely unexplored in gymnosperms. Here, the first genome-

Distribution and conservation of threatened gymnosperms in China
Global Ecology and Conservation, 2021 China is one of the diversity centers of gymnosperms. Nearly one-fifth (195 species) of gymnosperms are located in China, but 69 species are threatened. To date, the conservation status of gymnosperms, especially threatened gymnosperms in China, remains ...
