Is there silicon in flowers and what does it tell us? [PDF]

Ecol Evol, 2023
Whether flowers accumulate Si and what the implications may be was largely unknown. We analysed the flowers separated into their different anatomical parts, and leaves of different taxa. We conclude that flowers contain Si, in large amounts for some species, and hence the function of this element warrants more attention.

Roots of Indian heliotrope (Heliotropium indicum) produce simple pyrrolizidine alkaloids using the same homospermidine oxidase involved in biosynthesis of complex pyrrolizidine alkaloids in aerial parts. [PDF]

Plant Biol (Stuttg)
Indian heliotrope uses the same oxidase to produce complex pyrrolizidine alkaloid esters in aerial parts and simple pyrrolizidine alkaloids in roots. Abstract Pyrrolizidine alkaloids (PAs) are toxic specialized metabolites found in several plant lineages with independent evolutionary origins.

Chromosome-scale reference genome of <i>Pectocarya recurvata</i>, the species with the smallest reported genome size in Boraginaceae. [PDF]

Appl Plant Sci
Abstract Premise Pectocarya recurvata (Boraginaceae, subfamily Cynoglossoideae), a species native to the Sonoran Desert (North America), has served as a model system for a suite of ecological and evolutionary studies. However, no reference genomes are currently available in Cynoglossoideae. A high‐quality reference genome for P.

Herbivory Dominates the Spring Diet of American Black Bears (<i>Ursus americanus</i>) in a Wood Bison (<i>Bison bison athabascae</i>) Neonatal Range, Suggesting Minimal Bison Consumption. [PDF]

Ecol Evol
In this study, we used scat analysis and DNA metabarcoding to analyze the spring diet of black bears in the neonatal range of a small, threatened wood bison herd in northeast Alberta to assess predation risk of neonate bison. Our results suggest that consumption rates of bison are low and that predation risk to neonate wood bison, during the RLBH's ...

Familial classification of the Boraginales [PDF]

TAXON, 2016
AbstractThe Boraginales are now universally accepted as monophyletic and firmly placed in Lamiidae. However, a consensus about familial classification has remained elusive, with some advocating recognition of a single, widely variable family, and others proposing recognition of several distinct families.

The biosynthesis, degradation, and function of cell wall β‐xylosylated xyloglucan mirrors that of arabinoxyloglucan

New Phytologist, Volume 240, Issue 6, Page 2353-2371, December 2023., 2023
Summary Xyloglucan is an abundant polysaccharide in many primary cell walls and in the human diet. Decoration of its α‐xylosyl sidechains with further sugars is critical for plant growth, even though the sugars themselves vary considerably between species. Plants in the Ericales order – prevalent in human diets – exhibit β1,2‐linked xylosyl decorations.

MORFOANATOMÍA FOLIAR COMO EVIDENCIA TAXONÓMICA EN LA DELIMITACIÓN DE LAS ESPECIES QUE FORMAN EL COMPLEJO Varronia bullata (CORDIACEAE)

Tecnociencia, 2020
El género neotropical Varronia P. Browne es uno de los más problemáticos, taxonómicamente, entre las Boraginales. Esto puede deberse a la frecuente superposición de los límites entre la variación intra e interespecífica de algunos caracteres.
