RESUMO
In the Southern Great Plains, wheat cultivars have been selected for a combination of outstanding yield and drought tolerance as a long-term breeding goal. To understand the underlying genetic mechanisms, this study aimed to dissect the quantitative trait loci (QTL) associated with yield components and kernel traits in two wheat cultivars `TAM 112' and `Duster' under both irrigated and dryland environments. A set of 182 recombined inbred lines (RIL) derived from the cross of TAM 112/Duster were planted in 13 diverse environments for evaluation of 18 yield and kernel related traits. High-density genetic linkage map was constructed using 5,081 single nucleotide polymorphisms (SNPs) from genotyping-by-sequencing (GBS). QTL mapping analysis detected 134 QTL regions on all 21 wheat chromosomes, including 30 pleiotropic QTL regions and 21 consistent QTL regions, with 10 QTL regions in common. Three major pleiotropic QTL on the short arms of chromosomes 2B (57.5 - 61.6 Mbps), 2D (37.1 - 38.7 Mbps), and 7D (66.0 - 69.2 Mbps) colocalized with genes Ppd-B1, Ppd-D1, and FT-D1, respectively. And four consistent QTL associated with kernel length (KLEN), thousand kernel weight (TKW), plot grain yield (YLD), and kernel spike-1 (KPS) (Qklen.tamu.1A.325, Qtkw.tamu.2B.137, Qyld.tamu.2D.3, and Qkps.tamu.6A.113) explained more than 5% of the phenotypic variation. QTL Qklen.tamu.1A.325 is a novel QTL with consistent effects under all tested environments. Marker haplotype analysis indicated the QTL combinations significantly increased yield and kernel traits. QTL and the linked markers identified in this study will facilitate future marker-assisted selection (MAS) for pyramiding the favorable alleles and QTL map-based cloning.
RESUMO
BACKGROUND: In this study we aimed to determine knowledge, attitudes, and behaviors of mosque imams regarding organ donation. MATERIAL/METHODS: This study involved 322 mosque imams working in Kahramanmaras, a city in the Mediterranean region of Turkey. A questionnaire was used to determine participants' sociodemographic characteristics, knowledge, attitudes, and behaviors regarding organ donation. RESULTS: Out of a total of 322 participants, 253 (78.6%) stated that organ donation is allowed in Islam, while 5 (1.6%) expressed that it is religiously forbidden, and 64 (19.9%) stated that they have no idea about the issue. Only 2 (0.6%) participants were registered organ/tissue donors, wile 320 (99.4%) were not. Out of all participants, 72 (22.4%) imams were willing to donate organs. Forty-six (14.3%) imams had previously received basic training about organ donation, and 166 (51.6%) were willing to attend a related training. Television programs and healthcare professionals were the most common means of learning about organ donation. Educational programs by healthcare professionals for imams and the public were proposed to be effective in increasing the number of organ donations. CONCLUSIONS: This study revealed that the knowledge of mosque imams regarding organ donation is poor and they had little willingness to donate their organs. Interestingly, many imams had no knowledge about organ donation under Islam. Collaboration of media, healthcare professionals, and mosque imams regarding organ donation might help increase organ donation.
