Using the SERK gene as a marker during the examination of either carrot hypocotyls explants [ 3], immature zygotic embryos of sunflower [ 20], leaf explants of Dactylis glomerata L. (Poaceae) [ 30], or developing ovules and embryos of Arabidopsis [ 31].
Blooms also has followed a growing trend toward variegated-leaved plants by introducing a variegated-leaf sunflower (Heliopsis) named Loraine Sunshine.
In sunflower, the dominant mutant Basilicum Leaf (BL) is characterized by prominent downward leaf curling.
A differential exudation of phenolic compound coumarins (like scopolin, ayapin and scopoletin) in the leaf surface of sunflower genotypes prevents rust germ tube growth and appressorium differentiation (Prats et al. 2007).
For chilling stress, sunflower seedlings at the two-leaf stage were subjected to 10°C (adapted from Huang et al).
We have shown that selection directly favors early season leaf length in a sunflower crop wild hybrid zone, but we have not identified the selective pressure(s) responsible.
The efficacy of a double-barreled electrode containing a proton ionophore in the ion-selective barrel is demonstrated in situ in the leaf apoplasm of pea (Pisum) and sunflower (Helianthus).
A deflated balloon from the annual picnic on a recent Saturday hangs from a leaf of an eight-foot sunflower, not far from the three places to barbecue, including the cinder-block pit where the pigs are roasted.
It has been shown that AQPs play a role in the sunflower response to drought in both the leaf and the root (Ouvrard et al. [1996]; Sarda et al. [1997], [1999]).
