Summary
Complex plant bodies evolved in land plants. CLAVATA3-like peptides and conserved receptors in Physcomitrella patens are key to 3D growth innovation.
Area of Science:
- Plant biology
- Developmental biology
- Evolutionary biology
Background:
- Land plants exhibit complex multicellular bodies in both sporophyte and gametophyte generations.
- Morphological innovation, particularly 3D growth, is a hallmark of terrestrial plant evolution.
Purpose of the Study:
- To investigate the molecular mechanisms underlying 3D growth in land plants.
- To identify key signaling molecules and receptors involved in plant morphological evolution.
Main Methods:
- Utilized Physcomitrella patens as a model organism for studying early land plant evolution.
- Investigated the function of CLAVATA3-like peptides and their associated receptors in regulating plant growth and development.
Main Results:
- CLAVATA3-like peptides were found to function through conserved receptors in Physcomitrella patens.
- These peptides act as crucial regulators for the morphological innovation of 3D growth in land plants.
Conclusions:
- CLAVATA3-like signaling pathways represent a conserved mechanism for 3D growth in land plants.
- This study provides insights into the molecular basis of morphological diversification during plant terrestrialization.

37.7K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

01:54Convergent Evolution
33.0K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

02:55The Evidence for Evolution
48.3K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

The endosymbiont theory is the most widely accepted theory of eukaryotic evolution; however, its progression is still somewhat debated. According to the nucleus-first hypothesis, the ancestral prokaryote first evolved a membrane to enclose DNA and form the nucleus. Conversely, the mitochondria-first hypothesis suggests that the nucleus was formed after endosymbiosis of mitochondria.

3.8K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.

01:27Support Reactions in Three Dimensions
1.6K
Support reactions in three dimensions help maintain the stability and equilibrium of various structures and systems. These reactions prevent the system from translating and rotating, ensuring the design can withstand external forces and perform its intended function efficiently and safely. Some of the supports providing support reactions in three dimensions are discussed below:
Ball and Socket Joint is one of the supports allowing free rotation about any axis. This freedom of rotation is...
