1 mar 2023 · These will elucidate the nature of ancestral Archaeplastida, Viridiplantae, and Streptophyta, and will highlight variation within early plant lineages. Model organisms will also be vital to establish the function of genes across early plant evolution and within younger plant ancestors.
Evidence of the emergence of embryophyte land plants first occurs in the middle Ordovician (~ 470 million years ago), and by the middle of the Devonian (~ 390 million years ago), many of the features recognised in land plants today were present, including roots and leaves.
31 paź 2022 · Evolution of the primary archaeplastids reshaped the hydrosphere, cryosphere, and lithosphere , and the subsequent evolution of land plants transformed the continents and created new habitats, thus promoting diversity across the tree of life including animals , fungi , bacteria , and archaea.
31 paź 2022 · Plant (archaeplastid) evolution has transformed the biosphere, but we are only now beginning to learn how this took place through comparative genomics, phylogenetics, and the fossil record.
Plant (archaeplastid) evolution has transformed the biosphere, but we are only now beginning to learn how this took place through comparative genomics, phylogenetics, and the fossil record.
Together, these insights inform on the coevolution of plants and the Earth system that transformed ecology and global biogeochemical cycles, increased weathering, and precipitated snowball Earth events, during which they would have been key to oxygen production and net primary productivity (NPP).
13 wrz 2024 · The evolutionary history of plants is recorded in fossils preserved in lowland or marine sediments. Some fossils preserve the external form of plant parts; others show cellular features; and still others consist of microfossils such as pollen and spores.
