Although symbioses with nitrogen-fixing partners have evolved in several lineages in the rosid I clade, nodules are widespread only in legume taxa, being nearly universal in the papilionoids and in the mimosoid subfamily (e.g., mimosas, acacias) – which diverged from the papilionoid legumes around 58 million years ago, soon after the origin of the legumes.
Although symbioses with nitrogen-fixing partners have evolved independently in several lineages in the rosid I clade [18], nodules that host unicellular bacteria (collectively called "rhizobia") as the symbiont are reported only in the legumes and in the genus Parasponia in Ulmaceae [19].
We identified homology between TipE-like NaV channel regulators and vertebrate Slo-beta auxiliary subunits of big-conductance calcium-activated potassium (BKCa) channels, which suggests that ion channel regulatory partners have evolved distinct lineage-specific characteristics.
In addition, the mechanisms for exchanging information between the partners have evolved over time and played an important role throughout the collaboration-development process to meet the objective of ensuring continuity of care.
In the television special Pokémon Origins, Charizard is Red's partner, having evolved from Charmeleon at the beginning of the third segment.
As copper is a highly reactive reagent due to its potential to oxidize or reduce reaction partners, nature has evolved with a number of copper-binding und copper-handling proteins such as Atox1, COMMD1, COX 17, CCS resulting in a directed and safe handling of copper within the cell and the body [ 6].
Why, in many organisms, do centromeres become coupled with non-homologous partners when meiosis has evolved a series of elaborate mechanisms to ensure the pairing of homologous chromosomes?
Developed by a team of staff, faculty, and community partners, the tool kit has evolved, reflecting refinements of the model and user feedback.
In its quest to secure an attractive partner, this small, stocky bird has evolved bigger wing muscles and heavier bones that likely compromise its flying efficiency, biologist Kim Bostwick reported here last week at the annual meeting of the Society of Integrative and Comparative Biology.
Yackanich added that the business model has evolved: "Our publisher partners are dragging us very happily — and this was always the plan — into more of a platform model".
