Agrobacterium-MEDIATED TRANSFORMATION OF TWO HIGH OLEIC SUNFLOWER (Helianthus annuus L.) GENOTYPES: ASSESSMENT AND OPTIMIZATION OF IMPORTANT PARAMETERS
The establishment of an efficient Agrobacterium–mediated transformation protocol for a recalcitrant crop like high oleic sunflower genotypes, cv. Capella and SWSR2 inbred line, is presented in this paper. The protocol requires the identification and optimization of parameters affecting T-DNA delivery and plant regeneration. The basis for identifying the most appropriate conditions for transform...
متن کاملOptimization of Agrobacterium-mediated transformation of sunflower (Helianthus annuus L.) immature embryos
Sunflower is an important oilseed crop, however the genetic transformation of sunflower has been very challenging to date. In the present study, we describe a successful Agrobacterium-mediated transformation approach via somatic embryogenesis from immature zygotic embryos of sunflower. By optimizing the culture medium, we have achieved high efficiency (45.5%) of somatic embryogenesis with MS me...
متن کاملTOLERANCE OF SUNFLOWER (Helianthus annuus L.) TO IMAZETHAPYR
The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid "Zoltan" (S) was investigated under controlled conditions. Hybrids grown in pots were treated post-emergence with imazethapyr at the two pairs of leaves stage. Visual injury evaluation and vegetative parameters were recorded. ALS (acetolactate synthase) enzyme activ...
متن کاملComplete Mitochondrial Genome Sequence of Sunflower (Helianthus annuus L.)
This is the first complete mitochondrial genome sequence for sunflower and the first complete mitochondrial genome for any member of Asteraceae, the largest plant family, which includes over 23,000 named species. The master circle is 300,945-bp long and includes 27 protein-coding sequences, 18 tRNAs, and the 26S, 5S, and 18S rRNAs.
متن کاملCavitation fatigue and its reversal in sunflower (Helianthus annuus L.).
"Cavitation fatigue" is the increased susceptibility of a xylem conduit to cavitation as a result of its prior cavitation. It was investigated whether cavitation fatigue induced in vivo could be repaired in intact plants. Sunflowers (Helianthus annuus L.) were subjected to soil drought in the greenhouse. Native embolism and vulnerability to cavitation was measured in well-watered controls and a...
