Incidence and post-pollination mechanisms of nonrandom mating in Arabidopsis thaliana [PDF]
, 2009 Compatible pollinations from many differenttaxa display nonrandom mating. Here we describe a systemfor examining questions of nonrandom mating in Arabidopsisthaliana.

Nordic Journal of Botany, EarlyView.Petrocodon gracilis T.Ding & B.Pan and P. mirus X.Z.Shi, J.X.Fu & Li H.Yang are two recently described species exhibiting nearly identical morphology. To determine whether they represent the same taxon, we compared their type localities, type materials, and morphological features and conducted phylogenetic analyses using the nuclear internal ...

Peptide Signaling in Pollen-Pistil Interactions [PDF]
Plant and Cell Physiology, 2010 Plant fertilization is achieved through the involvement of various pollen-pistil interactions. Self-/non-self-recognition in pollination is important to avoid inbreeding, and directional and sustainable control of pollen tube growth is critical for the pollen tube to deliver male germ cells.

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy [PDF]
, 2020 In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes.

Hechtia mixtecana sp. nov. (Hechtioideae; Bromeliaceae), from Oaxaca, Mexico
Nordic Journal of Botany, EarlyView.Botanical explorations carried out in the state of Oaxaca, Mexico, led to the discovery of a new Bromeliaceae: Hechtia mixtecana,which is here described and illustrated. The new taxon is compared with the morphologically similar Hechtia fragilis, Hechtia lyman‐smithii, and Hechtia minuta.
