Abstract Land plants (embryophytes) constitute a monophyletic group that is well supported by morphological and molecular characters. Numerous vegetative and reproductive traits directly associated with life on land characterize the group (1) (Fig. 1).

Light-Response Curves in Land Plants
2018Light is the driving force for photosynthesis. Two techniques are commonly employed to help characterize the relationship between the light environment and photosynthesis in plants.Chlorophyll a fluorescence analysis is used to examine both the capacity for and the efficiency of the conversion of absorbed light into energy for photosynthesis ...

Numerous Transitions to Land in Green Plants: The ‘Other’ Land Plants
Journal of Phycology, 2002AbstractIn addition to the more conspicuous embryophyte group, numerous other green plant lineages have made successful transitions to land. Phylogenetic analyses using molecular data indicate that these lineages are primarily derived from freshwater ancestors, and include free‐living and lichen photobiont algae in the class Trebouxiophyceae, and ...

The impact of paleobotanical data on land plant systematics is greatest for ancient cladogenic events, resulting in isolated extant groups of divergent morphology. Paleobotanical data are therefore ideally suited to addressing problems in land plant macrosystematics, an area of botanical research that has received considerable attention over the last ...

The colonization of land by plants was one of the most important events in the earth’s history, setting the stage for the greening of the continents, increased oxygenation of the atmosphere, and the provision of food and habitat for the animals and microorganisms that evolved in parallel—and in many cases, diversified in their shadows.

Achieving zero extinction for land plants
Trends in Plant Science, 2023Despite the importance of plants for humans and the threats to their future, plant conservation receives far less support compared with vertebrate conservation. Plants are much cheaper and easier to conserve than are animals, but, although there are no technical reasons why any plant species should become extinct, inadequate funding and the shortage of

The evolution of land plant hemoglobins
Plant Science, 2012This review discusses the evolution of land plant hemoglobins within the broader context of eukaryote hemoglobins and the three families of bacterial globins. Most eukaryote hemoglobins, including metazoan globins and the symbiotic and non-symbiotic plant hemoglobins, are homologous to the bacterial 3/3-fold flavohemoglobins.

Annual Review of Ecology, Evolution, and Systematics, 2008
Considerable progress has been made in documenting evidence of very early plants starting in the basal Ordovician employing dispersed spore, phytodebris, and mesofossil data. Macrofossil evidence is sparse until Late Silurian, but recent new data are improving our understanding of aspects of earliest plants.

American Midland Naturalist, 1939
The earth is populated by an innumerable host of plants and animals, tio two of which, it is generally agreed, are exactly alike. Happily they do have such likenesses as enable us to classify them into less and more inclusive categories. The objects are discovered by us. Their likenesses are discovered.
