ABSCISSION. "During the course of development, plants shed entire organ systems through the process referred to as abscission. Abscission provides a mechanism for the removal of senescing or otherwise damaged organs and for the release of fruits as they ripen." https://lnkd.in/dNWP3KD View in LinkedIn

MASTER CONTROL. "Observations are consistent with the existence of master regulatory systems that can determine the timing of the senescence syndrome." https://lnkd.in/dNWP3KD View in LinkedIn

COMPLEXITY AND CONTROL. "The overall process of the senescence syndrome may be very complex, but it is still worth considering whether there are definable regulatory systems that have an overriding influence on the timing of the conversion from photosynthetic to salvage programs." https://lnkd.in/dNWP3KD View in LinkedIn

UPWARDLY MOBILE. "The evolution of multi-cellularity is characterized by the integration of lower-level units into higher-level entities, and hence is associated with a transition in individuality." http://rspb.royalsocietypublishing.org/content/early/2011/12/05/rspb.2011.1999.short View in LinkedIn

MASSIVE GENE CHANGES. "Continuing studies are likely to indicate that the conversion of a leaf from a photosynthetic system to a source of stored nutrients involves global changes in gene expression." https://lnkd.in/dNWP3KD View in LinkedIn

FACILITATED TRANSITION. "The evolutionary transition from unicellular to multicellular organisms is often referred to as one of the major transitions in evolution, even though many of the requirements for multicellularity probably evolved in unicellular ancestors, thus facilitating the transition." https://lnkd.in/dWyBAjJ View in LinkedIn

GENE DRIVEN. "It is clear that the senescence syndrome is a genetically controlled process that requires continuing gene expression." https://lnkd.in/dNWP3KD View in LinkedIn

UNIFYING HYPOTHESIS. "More generally, our results unify the role of group formation and genetic relatedness across multiple evolutionary transitions and provide an unmistakable footprint of how natural selection has shaped the evolution of life." http://www.sciencedirect.com/science/article/pii/S0960982213005678 View in LinkedIn

DISMEMBERING TEAM. "The hydrolysis of proteins and nucleic acids that accompanies senescence must be mediated by proteases and nucleases, respectively. Transaminases may function to shunt nitrogen into the most common mobile forms, glutamine and asparagine, and mobilization of lipids released from thylakoid membranes presumably requires conversion to sugars through the glyoxylate cycle." https://lnkd.in/dNWP3KD View in LinkedIn

CLONAL TRANSITIONS. "We found that species with clonal group formation were more likely to have undergone the major evolutionary transition to obligate multicellularity and had more cell types, a higher likelihood of sterile cells, and a trend toward higher numbers of cells in a group." http://www.sciencedirect.com/science/article/pii/S0960982213005678 View in LinkedIn
