Cavitation 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...
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 کاملIntraspecific variation in embolism resistance and stem anatomy across four sunflower (Helianthus annuus L.) accessions.
Drought-induced xylem embolism is a key process closely related to plant mortality during extreme drought events. However, this process has been poorly investigated in crop species to date, despite the observed decline of crop productivity under extreme drought conditions. Interspecific variation in hydraulic traits has frequently been reported, but less is known about intraspecific variation i...
متن کاملChloroplast DNA variation confirms a single origin of domesticated sunflower (Helianthus annuus L.).
Although sunflower was long thought to be the product of a single domestication in what is now the east-central United States, recent archaeological and genetic evidence have suggested the possibility of an independent origin of domestication, perhaps in Mexico. We therefore used hypervariable chloroplast simple-sequence repeat markers to search for evidence of a possible Mexican origin of dome...
