Plants, 2020 Understanding the pattern of species distribution and the underlying mechanism is essential for conservation planning. Several climatic variables determine the species diversity, and the dependency of species on climate motivates ecologists and bio ...

Variability of chromosome number and morphology and gymnosperm improvement [PDF]
Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2004 The causes of monotypic and polytypic variability of the gymnosperm chromosome complex were studied. The development of karyogram and idiograms of the species should be applied in the aim of upgrading the breeding method and technique.

Epigenetic stress memory in gymnosperms
Plant PhysiologyGymnosperms are long-lived, cone-bearing seed plants that include some of the most ancient extant plant species. These relict land plants have evolved to survive in habitats marked by chronic or episodic stress.

The relationship between shape and size of diaspores depends on being seeds or fruits [PDF]
, 2019 The relationship between the size and shape of diaspores was investigated in angiosperms and gymnosperms including determining if being a seed or fruit was a factor. Size was expressed as volume and shape as the departure from a perfect idealized sphere.

Evolution and structural variations in chloroplast tRNAs in gymnosperms
BMC Genomics, 2020 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.

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 ...

Phylogenetic reconciliation provides new insights into the evolutionary diversification of the glutamine synthetase gene family in seed plants. [PDF]
FEBS JPhylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...
