Quantitative trait loci for head bug resistance in sorghum

An experiment was conducted during the 1997/99 cropping seasons, in Mali, France, to study the inheritance for resistance to head bug (Eurystylus oldi) of sorghum progenies using quantitative trait loci (QTL) maps. Cultivars Malisor 84-7 (resistant) and S 34 (susceptible) were used as parents. To build the sorghum genetic map, 345 restriction fragment length polymorphism (RFLP) probes in combination with 6 restriction enzymes (BamHI, DraI, EcoRI, EcoRV, HindIII and SstI) were screened for their ability to reveal polymorphism. Thousand kernel weight (TKW) and germination rate at grain maturity were measured. Head bug damage was assessed visually on a 1 to 9 scale on the infested part of the panicle (NOTF2). Among the 345 RFLP probes, 81 revealed polymorphism between the parents. Additionally, 14 microsatellite markers gave amplification products. The genetic map based on Malisor 84-7 × S 34 includes 13 linkage groups (LGs) covering a total distance of 1160 cM. Three significant and 7 putative QTLs were detected. One QTL for TKW reduction that accounted for 13% of the phenotypic variation was detected on LG C2. For this QTL, resistance is conditioned by the Malisor 84-7 allele and is dominant. Two QTLs were detected on LG D and LG E for visual damage score under natural head bug infestation, explaining 16 and 26% of the phenotypic variation for this trait, respectively. Resistance from the QTL on LG D is conditioned by the S 34 allele, whereas resistance from the QTL on LG E is provided by the Malisor 84-7 allele. In both cases, resistance is recessive. No significant QTLs were detected for NOTF2 and germination rate, but co-localization of 2 putative QTLs for these traits was observed on LG G2, and in both cases, resistance is conditioned by the S 34 allele

Quantitative trait loci for head bug resistance in sorghum

Research focusing on families’ experiences of end-of-life care in an Irish context is largely absent. In a recent comprehensive review of end-of-life care for older people in acute and long-stay care settings in Ireland, O’Shea et al (2008) excluded the perspective of families from the study. This study aims to reduce that deficit by exploring families’ experiences and perceptions of the end-of-life care received by their loved in the context of a private nursing home setting. The report is comprised of discussions on: methodology; review of existing literature and interpretation of the data gathered thorough interviews of relatives who admitted a family member to nursing homes. The data revealed how families noticed their loved ‘grow infirm, they age’ (Elias 1985 p.3) focusing on their journey through the ageing process. It uncovers the emotional journey of family members when they come to the realisation of the limitations of their ability to provide care for their loved ones. The majority of participants came to the realisation they could no longer provide the care their loved one needed. They had to navigate both the cultural ideology and promises made that nursing homes was the place of last resort for caring for a family member. Finding a nursing home is not easy and the majority of participants reviewed a number of nursing homes until they found what they were looking for. The decision to admit their loved one was based upon their initial instinctive reaction to the home for the majority ‘it felt like home’. Life within a nursing home is unpacked, from the quality of life of residents to the quality of care and the process of partings. This report is centered on the stories people told of living with a loved one who was ill and how they journeyed with them until their death
