Transgenic Sunflower (Helianthus annuus)
2000The genus Helianthus (Asteraceae) includes about 100 species (Watson 1929), the majority of which are native to North America. The genus provides two food plants, H. annuus, the sunflower, and H. tuberosus, the topinambour or Jerusalem artichoke. Several varieties of H.

Sunflower (Helianthus annuus L.)
2014Sunflower (Helianthus annuus L.) is still considered as a recalcitrant species to in vitro culture and transformation in spite of the publication of different protocols. Here we describe a routine transformation system of this crop which requires mature HA89 genotype seeds and Agrobacterium tumefaciens EHA105 strain for gene delivery, being both easily

Sunflower (Helianthus annuus) Seed
2020Sunflower (Helianthus annuus L.) is an important agricultural crop grown for its seeds worldwide. Globally, sunflower is the fourth largest source of vegetable oil next to soybean, palm and rapeseed. Besides edible oil, it is grown for its fruits both for human and livestock consumption. Production of sunflower seed has increased over the years because

Micropropagation of Sunflower (Helianthus annuus L.)
1992The common sunflower (Helianthus annuus L.) is a member of the Compositae (Asteraceae) family. Its name (from the Greek helios, sun, and anthos, flower) is derived from the heliotropic movement of the sunflower’s head (nutation). Grown for its seed, this species is one of the most important suppliers of vegetable oil, and is now fairly widely ...

Diffusible gibberellins and phototropism in Helianthus annuus
Planta, 1972Endogenous gibberellins were obtained in agar from the lower cut surface of upright sunflower shoot-tips. Exposure to unilateral light of the tips standing on agar, with the lower cut ends bisected by a vertical glass barrier at right angles to incident light, resulted in approximately 8 times the quantity of gibberellins moving into the agar below the

Characterization of Helianthus annuus L. storage proteins
Journal of Agricultural and Food Chemistry, 1989A rapid method is described for isolating the globulin fraction (helianthinin) of sunflower seeds (Helianthus annum L.). The protein was characterized by chromatography and electrophoresis and compared with the globulin extracted from protein bodies.

Gibberellins in seeds of Helianthus annuus
Phytochemistry, 1988Abstract Fourteen gibberellins (GAs) have been identified in seeds of Helianthus annuus . They comprise the previously known GA 1 , GA 4 , GA 19 , GA 20 , and GA 45 , and nine new 15β-hydroxyGAs. Of the new GAs, 15β-hydroxyGA 20 and 15β-hydroxyGA 1 have been previously synthesized chemically from GA 3 and are now assigned the numbers GA 67 and ...
