Engineering of Transmembrane Alkane Monooxygenases to Improve a Key Reaction Step in the Synthesis of Polymer Precursor Tulipalin A. [PDF]

Angew Chem Int Ed Engl
A biosynthesis route for the polymer precursor tulipalin A starting from isoprenyl acetate is proposed. The alkane monooxygenase AlkB catalyzes the chemoselective terminal hydroxylation of isoprenyl acetate. Rational enzyme engineering further increased the activity of the membrane enzyme.

Phylogeny and Comparative Analysis for the Plastid Genomes of Five Tulipa (Liliaceae). [PDF]

Biomed Res Int, 2021
Species of Tulipa (Liliaceae) are of great horticultural importance and are distributed across Europe, North Africa, and Asia. The Tien Shan Mountain is one of the primary diversity centres of Tulipa, but the molecular studies of Tulipa species from this location are lacking.

Spatial distribution patterns and formation of global spermatophytes. [PDF]

J Integr Plant Biol
The global Spermatophyte Spatial Evolutionary System defines 18 distribution types and six supertypes across three floristic elements, primarily formed between the Eocene and Miocene and shaped by climate, long‐distance dispersal, and tectonic movement, revealing that similar distribution patterns of spermatophytes were driven by comparable formation ...

EL CARIOTIPO DE BOMAREA PATINII BAKER SUBSP. PATINII (ALSTROEMERIACEAE) THE KARYOTYPE OF BOMAREA PATINII BAKER SUBSP. PATINII (ALSTROEMERIACEAE)

Gayana: Botanica, 2008
The karyotype oí Bomarea patinii Baker subsp. patinii from Colombia was examined. The species has a karyotype 2n = 2x= 18, with a haploid formula 2m + lsm+ 5st+ lt-sat. The reported karyotype is asymmetric (Asl %= 75.51).

Osmoxylon-like fossils from early Eocene South America: West Gondwana-Malesia connections in Araliaceae. [PDF]

Am J Bot
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

A genome‐wide phylogeny and the diversification of genus Liriomyza (Diptera: Agromyzidae) inferred from anchored phylogenomics

Systematic Entomology, Volume 48, Issue 1, Page 178-197, January 2023., 2023
Phylogenetic relationships are reconstructed among the Liriomyza leafminers using phylogenomic analysis of nuclear gene loci obtained by anchored hybrid enrichment (AHE). Trees inferred using multiple data types and analysis methods are congruent and individual clade support confirms morphological species groups and relationships among them.

Large flowers can be short‐lived: Insights from a high Andean cactus

Ecology and Evolution, Volume 12, Issue 8, August 2022., 2022
We explored the context‐dependent large flower/short flower longevity hypothesis in Eriosyce curvispina (Cactaceae), a large‐flowered species of the semi‐arid central Chilean Andes. We determined breeding system, flower visitation rates and open‐pollination fruit set and quantified floral water content.

Comparative genome analysis and phylogenetic relationship of order Liliales insight from the complete plastid genome sequences of two Lilies (Lilium longiflorum and Alstroemeria aurea). [PDF]

PLoS ONE, 2013
Monocots are one of the most diverse, successful and economically important clades of angiosperms. We attempt to analyse the complete plastid genome sequences of two lilies and their lengths were 152,793bp in Lilium longiflorum (Liliaceae) and 155,510bp ...
