Geologically calibrated mammalian tree and its correlation with global events, including the emergence of humans

open access: yesEcology and Evolution, Volume 13, Issue 12, December 2023., 2023
A robust minimum age tree shows post K–Pg Placentalia radiation, and subsequent extensive radiation connected to exponentially increased base substitution (mutation) rate including generation of Homo sapiens. This Neogene radiation may have been triggered by expansion of C4 grasses that decreased atmospheric CO2, resulting in global cooling and ...

Genetic Diversity and Population Differentiation of Guignardia mangiferae from “Tahiti” Acid Lime

open access: yesThe Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
Among the citrus plants, “Tahiti” acid lime is known as a host of G. mangiferae fungi. This species is considered endophytic for citrus plants and is easily isolated from asymptomatic fruits and leaves. G. mangiferae is genetically related and sometimes confused with G. citricarpa which causes Citrus Black Spot (CBS).

Genetic Diversity and Population Differentiation of the Causal Agent of Citrus Black Spot in Brazil

open access: yesThe Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
One of the most important diseases that affect sweet orange orchards in Brazil is the Citrus Black Spot that is caused by the fungus Guignardia citricarpa. This disease causes irreparable losses due to the premature falling of fruit, as well as its severe effects on the epidermis of ripe fruit that renders them unacceptable at the fresh fruit markets ...
