Autopolinización y su implicancia en la invasividad de Helianthus annuus ssp. annuus y H. petiolaris [PDF]

open access: yes, 2014
Helianthus petiolaris and H. annuus are exotic invaders that have spread widely in central Argentina in the last 70 years. As other annuals of the same genus, these species are outcrossers bearing a sporophytic self-incompatible mechanism.

Metabolomic and Single‐Cell Transcriptomic Analyses Shed Light on Secondary Metabolite Profiling and Potential Developmental Dynamics of Glandular Trichomes in Artemisia argyi

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant glandular trichomes (GTs) are characterised by their ability to synthesise and store abundant secondary metabolites of significant biological importance. The medicinal plant Artemisia argyi exhibits a dense covering of GTs, yet the precise metabolic compositions and the developmental molecular dynamics of A.

Plant Lipid Droplets and Derived Lipidic Nano‐Assemblies: Structure, Biogenesis and Pharmaceutical Applications

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Lipid droplets (LDs) serve as the primary storage site for neutral lipids in plant cells, with growing evidence supporting many additional biological roles, such as in lipid homeostasis, signalling, trafficking, inflammatory responses and inter‐organelle communication.

Germplasm resources of oilseed crops—sunflower, soybeans, and flax

open access: yesCalifornia Agriculture, 1977
Sunflowers (Helianthus annuus L.) are presently grown on a limited acreage in California, but because of their potential we maintain two germplasm collections: (1) domestic types, of both oilseed and confectionary varieties, and (2) wild species ...

Jasmonate‐Activated AaWRKY9–AabHLH93/AabHLH93–AaMYB7 Complexes Balance Artemisinin Biosynthesis in Artemisia annua

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Artemisinin, an antimalarial sesquiterpene lactone, is biosynthesized in glandular trichomes of Artemisia annua. Although numerous transcription factors have been demonstrated to regulate artemisinin biosynthesis, the molecular mechanisms underlying the high expression of artemisinin‐associated biosynthetic enzyme and transcription factor ...
