Ecogeography and utility to plant breeding of the crop wild relatives of sunflower (Helianthus annuus L.)

open access: yesFrontiers in Plant Science, 2015
Crop wild relatives (CWR) are a rich source of genetic diversity for crop improvement. Combining ecogeographic and phylogenetic techniques can inform both conservation and breeding.

A new way of valorizing biomaterials: the use of sunflower protein for 1 a-tocopherol microencapsulation [PDF]

open access: yes, 2013
Biopolymer based microparticles were efficiently prepared from sunflower protein (SP) wall material and a-tocopherol (T) active core using a spray-drying technique. Protein enzymatic hydrolysis and/or N-acylation were carried out to make some structural

Foliar-applied glyphosate substantially reduced uptake and transport of iron and manganese in sunflower (helianthus annuus L.) plants [PDF]

open access: yes, 2006
Evidence clearly shows that cationic micronutrients in spray solutions reduce the herbicidal effectiveness of glyphosate for weed control due to the formation of metal-glyphosate complexes.

MADS-box genes controlling inflorescence morphogenesis in sunflower [PDF]

open access: yes, 2008
MADS-box genes play an important role in plant ontogeny, particularly, in the regulation of floral organ induction and development. Eight full-length cDNAs of HAM genes (Helianthus annuus MADS) have been isolated from sunflower.

Analysis of codon usage bias of WRKY transcription factors in Helianthus annuus

open access: yesBMC Genomic Data, 2022
Background The phenomenon of codon usage bias is known to exist in many genomes and is mainly determined by mutation and selection. Codon usage bias analysis is a suitable strategy for identifying the principal evolutionary driving forces in different ...

Increasing leaf hydraulic conductance with transpiration rate minimizes the water potential drawdown from stem to leaf. [PDF]

open access: yes, 2014
Leaf hydraulic conductance (k leaf) is a central element in the regulation of leaf water balance but the properties of k leaf remain uncertain. Here, the evidence for the following two models for k leaf in well-hydrated plants is evaluated: (i) k leaf is
