A revision and key to the 23 species and eight subspecies of Poa (including Dissanthelium) known to occur in Mexico is provided. All voucher specimens seen are cited for accepted taxa, except Poa annua for which one voucher per state is provided. Taxa not previously known from, or poorly understood in, Mexico are discussed.Poa palmerisp. nov. is endemic to forested slopes of the Sierra Madre Or...

The Indolines of the Poeae and Triticeae are economically important as they control seed hardness (endosperm texture) in wheat other cereals. Here an silico analysis was performed at nucleotide protein levels across Avena, Aegilops, Brachypodium, Hordeum, Oryza, Sorghum, Secale, Triticum taxa. In addition, Vromindolines from cv. Hayden oat were isolated, cloned sequenced. paralogous Vin-1, Vin-...

Puccinellia tenuiflora is an alkaline salt-tolerant monocot found in saline-alkali soil in China. To identify the genes which are determining the higher tolerance of P. tenuiflora compared to bicarbonate sensitive species, we examined the responses of P. tenuiflora and a related bicarbonate-sensitive Poeae plant, Poa annua, to two days of 20 mM NaHCO3 stress by RNA-seq analysis. We obtained 28 ...

Circumscriptions of and relationships among many genera and suprageneric taxa of the diverse grass tribe Poeae remain controversial. In an attempt to clarify these, we conducted phylogenetic analyses of >2400 new DNA sequences from two nuclear ribosomal regions (ITS, including internal transcribed spacers 1 and 2 and the 5.8S gene, and the 3'-end of the external transcribed spacer (ETS)) and fi...
