In Caenorhabditis species, among the six "vulva precursor cells", only one termed P3.p shows fate evolution within and among species.In contrast, in Oscheius species(sister genus)other vulva precursor cells fates evolve faster, named P4.p and P8.p.
They discuss the taxonomy of these genera and the sister genus Talaromyces; techniques currently used in relation to genomics; a genomic perspective on biological processes of pathogenicity, carbon starvation, sulfur metabolism, feruloyl esterases, secondary metabolism, and pH modulation in these fungi; and an approach to generating targeted mutants using genomics to gain more insight into the mechanism underlying enzyme production.
thesis committee, MIT microbiologist Penny Chisholm, tells the story of a photosynthetic bacterium that she discovered called Prochlorococcus, which is a sister genus to Synechococcus.
Kerodon was traditionally included within the subfamily Caviinae with guinea pigs and its relatives, but now it is placed as sister genus from Hydrochoerus within the Hydrochoerinae subfamily, according to new molecular studies by Rowe and Honeycutt (2002).
On morphological grounds it seems safe to say that the ancestor of the lineage was probably a plant with a lateral-winged samara that reached western Mexico via long-distance dispersal from southern South America, where Camarea, the sister genus, occurs.
After analysis of data obtained from the literature and subsequent evaluation of diagnostic generic/species features, the taxonomic position of the genus Tritogenia together with its sister genus Michalakus was seen in a new light.
Sister genus Pehria Sprague, with approximately the same distributional range and habitats in Central and South America as Adenaria, shares a similar seed structure but differs by a selerenchymatous, rather than a spongy, mesotesta (pers.
