Is the grass *always* greener on the other side?
Maybe Barberá et al. know! They certainly know a lot about #phylogenetics and #reticulation among koelerioid clades. Don't miss this fascinating #OpenAccess study published in #JSE!

Maximum-likelihood tree inferred from combined plastid (rpl32-trnL, rps16 intron, and rps16-trnK) and ITS sequences of Koeleriinae Clades A and B, and Sibirotrisetum. Exemplars with incongruent placements in plastid DNA and ITS are coded orange and red, respectively. Samples of perennials are labeled in Arial type, and annuals in Times New Roman. Bootstrap and posterior probability values for nodes are posted above and below the branches, respectively.

Peterson et al. investigate the #phylogeny, #biogeography, #reticulation, and #classification of Agrostis in their latest study published in #JSE!

Parsimony chloroplast haplotype network for Agrostis (A) species and relatives (Cal = Calamagrostis, Ch = Chaetotropis, La = Lachnagrostis, P = Podagrostis, Poly = Polypogon, Tripl = Triplachne) inferred from rpl32-trnL sequence data. Each link between haplotypes represents one mutational difference. The geographic distribution of haplotypes is as follows: red = North America, orange = South America, light green = Africa, dark green = Asia, blue = Europe, purple = Australia, and pink = East Asia.

(7/7) And the winner was Crossroad.

To explain the genetic puzzle in the Philippines, we concluded that two of the genus' major lineages, one Pacific, one African-Asian populated the Philippines when they came in reach and found enough place (niches) to radiate there. In course of this (early) contact, inter-lineage mixing occured (#CoralOfLife #reticulation) leading to the modern-day genetic mosaic.

Towards that end, it may be worthwhile to explore the incongruent signals (see gCF results): what are the alternatives?

Between-gene incongruence and phylogenomic branch supports < 100 may relate to lack of discriminative signal (fast ancient radiations) and ILS. Or evidences evolutionary #reticulation

A dichotomous tree may simply be not comprehensive enough, for any group of plants #CoralOfLife

Includes a few posts on viruses, too, especially towards the end. Teaser attached.

Are #grasses your thing?
How about #phylogenetics and #reticulation among koelerioid clades?
If you answered🤩to any of these, then today is your lucky day! Read part 1 of a new study from Barberá et al. in #JSE!
