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 ...

Evolution and structural variations in chloroplast tRNAs in gymnosperms

BMC Genomics, 2021
Background Chloroplast transfer RNAs (tRNAs) can participate in various vital processes. Gymnosperms have important ecological and economic value, and they are the dominant species in forest ecosystems in the Northern Hemisphere.

Dry Climate Filters Gymnosperms but Not Angiosperms through Seed Mass

Diversity, 2023
In the context of climate change in recent years, the fate of woody plant seed has an important impact on forest regeneration. Seed mass is an important reproductive strategy of plants. There are huge differences between gymnosperms (mainly conifers) and

Classification of Vascular Plants in Vietnam According to Modern Classification Systems

Plants, 2023
Vietnam is extremely rich in biodiversity, with a remarkable range of habitats and more than 13,500 species of vascular plants recorded for the flora of Vietnam. This number represents about 3 to 5% of the world’s diversity of vascular plants.

An Anatomically Preserved Cone-like Flower from the Lower Cretaceous of China

Life, 2023
Although diverse fossil angiosperms (including their reproductive organs) have been reported from the Early Cretaceous, few of them are well-documented due to poor preservation and limited technologies available to apply. For example, paraffin sectioning,

Comparative Genomics Analysis of Repetitive Elements in Ten Gymnosperm Species: “Dark Repeatome” and Its Abundance in Conifer and Gnetum Species

Life, 2021
Repetitive elements (RE) and transposons (TE) can comprise up to 80% of some plant genomes and may be essential for regulating their evolution and adaptation.

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 ...

Isolation of an AGAMOUS homolog from Zamia muricata [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2020
AGAMOUS (AG) is a class C MADS-box gene that plays an important role in the development of reproductive organs in angiosperms and gymnosperms. Here, an AGAMOUS homolog was isolated from male and female Zamia muricata.
