The sfr mutations, which result in sensitivity to freezing after cold acclimation, define genes that are required for freezing tolerance. We tested plants homozygous for mutations sfr2 to sfr7 for cold-induced gene expression and found that sfr6 plants were deficient in cold-inducible expression of the genes KIN1 , COR15a , and LTI78 , which all contain the(More)
The sensitive to freezing2-1 (sfr2-1) mutation causes freezing sensitivity in Arabidopsis thaliana. By mapping, transgenic complementation, and sequencing, sfr2-1 was revealed to be a mutation in gene At3g06510. A new knockout allele was obtained, and its identical freezing-sensitive phenotype confirmed that the SFR2 gene product is essential for freezing(More)
The sfr3 mutation causes freezing sensitivity in Arabidopsis thaliana. Mapping, sequencing, and transgenic complementation showed sfr3 to be a missense mutation in ACC1, an essential gene encoding homomeric (multifunctional) acetyl-CoA carboxylase. Cuticle permeability was compromised in the sfr3 mutant when plants were grown in the cold but not in the(More)
BACKGROUND The demand for transplantable organ continues to exceed supply, particularly in minority patient populations. We explored the factors influencing organ donation attitude within the Arab American community. METHODS Secondary data analysis from a face-to-face survey administered in late 2003 to 1016 adults from a representative population-based(More)

Urethroplasty is the preferred surgical approach for the management of urethral stricture disease. To date, no standard has been established to evaluate stricture recurrence after urethral reconstruction, though both invasive and non-invasive methods are used widely. In this article we review the role of noninvasive testing and questionnaires in urethral(More)
