1BL.1RS易位系对小麦籽粒性状的遗传效应分析          下载免费PDF全文

肖永贵  刘新伦  何胜美 《西北农林科技大学学报(自然科学版)》2011,39(5):140-146

【目的】研究1BL.1RS易位对小麦籽粒特征的影响及其遗传效应,为小麦籽粒性状的遗传改良提供理论依据。【方法】以豫麦49/周麦16杂交后代的176个F5重组自交系为材料,于2008-2010年连续2年对籽粒性状进行分析,并结合SSR和STS标记对1BL.1RS染色体进行籽粒性状的QTL检测。【结果】小麦籽粒性状中粒长和密度因子主要受基因型影响,千粒质量、粒宽、周长、面积及形态因子等性状受基因型和环境及其互作的影响较大,1BL.1RS易位能显著提高千粒质量、粒长、粒宽、周长和面积,但对形态因子和密度因子影响不显著。千粒质量与粒长、粒宽和密度因子均呈极显著偏正相关;而粒长和粒宽呈极显著偏负相关。位于1BL.1RS染色体短臂上的HVM20-AF1/AF4标记区间携带有控制千粒质量、粒宽和面积的QTL,可解释17.2%～21.0%的表型变异;AF1/AF4-Xg-wm582标记区间存在有控制粒长和周长的QTL,分别解释21.5%和14.9%的表型变异;与Nor-4紧密连锁的形态因子QTL可解释12.2%的表型变异,受环境影响较大。【结论】1RS携带有提高千粒质量、粒长、粒宽、周长、面积及形态因子的QTL,通过分子标记跟踪选择1BL.1RS易位系可有效改良小麦籽粒性状,进而提高千粒质量和产量。  相似文献

水稻生长、根系生理特性和ABA含量的基因型差异与耐盐性的关系   总被引：1，自引：0，他引：1  

张振华  刘强  宋海星  荣湘民 《植物营养与肥料学报》2011,17(5):1035-1043

为进一步揭示不同基因型水稻耐盐性差异的生理机制,探明盐胁迫初期根部激素ABA对水稻耐盐性的调控机理。于2009年10月～2010年2月在严格控制水、温、光和营养元素供应的国际水稻研究所人工气候室进行水培试验。结果表明,盐胁迫条件下耐盐基因型（IR651）相对于敏感基因型（IR29）保持了更高的生物量,稀释了植株体内盐分离子的浓度而减轻盐胁迫。两水稻基因型盐胁迫条件下对盐分的总吸收量并无明显差异,IR651根部较强的耐盐性和较大的生物量可以储存更多的Na+,从而减少Na+向地上部的转运量。盐胁迫初期IR651根部ABA的大量合成是叶片蒸腾速率显著降低的主要原因,从而抑制了盐分离子的大量吸收,大大减轻了盐胁迫初期大量盐分离子吸收对植株造成的不可恢复性伤害。可见,盐胁迫条件下耐盐基因型较大的生物量、根的生理特性以及盐胁迫初期ABA的特有调控都大大增强了其耐盐胁迫性能,是耐盐基因型相对敏感基因型有更强耐盐胁迫能力的重要原因。  相似文献   

Gender and occupational health and safety requirements among Saskatchewan farm adolescents     

Crouchman E  Ding K  Hagel L  Dosman J  Pickett W;Saskatchewan Farm Injury Cohort Study Team 《Journal of agricultural safety and health》2011,17(4):343-354

Children on farms perform hazardous work that exposes them to risks for injury. Hazards include operation of heavy machinery, working with limited supervision, working at heights, and performing work prohibited by law in other industries. Incidence rates and patterns of injury are known to differ between boys and girls on farms. Farm adherence to occupational health and safety practices, and whether such practices vary by gender, has received limited study in this occupational setting. The objective of this study was to evaluate associations between gender and work practices, and required occupational health and safety practices, within a sample of adolescent children age 12 to 18 years living on Saskatchewan farms. A cross-sectional study was performed. Measures were obtained by self-report. We compared requirements for boys and girls on the following: (1) use of personal protective equipment (PPE), (2) conduct of specific hazardous jobs, (3) training and supervision for equipment work, and (4) training and supervision for large animal work. A total of 434 children were identified, and 297 (68%) met the eligibility criteria. Of these, 170 were boys (57%) with a mean age of 14.5 years (SD 1.9). Occupational health and safety requirements varied by gender; girls were less likely to be required to use PPE (adjusted OR 2.39; 95% CI: 1.16, 4.94). There was no evidence of an association between gender and the conduct of hazardous work. Gender patterns in required training and supervision for work suggested disadvantages for girls, but were not significant. Adolescent girls and boys both performed hazardous jobs on the farm. Girls were as likely to conduct hazardous jobs but not to be required to use PPE. This gender disparity may indicate a need for a public health approach that recognizes gender as a determinant of work assignment and of health and safety practices on farms.  相似文献   

Current evidence of skin barrier dysfunction in human and canine atopic dermatitis     

Marsella R  Olivry T  Carlotti DN;International Task Force on Canine Atopic Dermatitis 《Veterinary dermatology》2011,22(3):239-248

Atopic dermatitis (AD) is a multifaceted disease resulting from a complex interaction between environmental and genetic factors. Both of these factors can shape skin barrier function and the immunological response of predisposed patients. There is increasing evidence that an impaired skin barrier plays a role in both human and canine AD. Although many primary skin barrier defects had already been documented in the past in humans, the recent identification of the filaggrin mutations and the fact that such mutations are now considered the most important risk factor for development of AD have further emphasized the relevance of epidermal dysfunction in human AD. Much less is known in veterinary medicine, but evidence is rapidly building to support a role for skin barrier dysfunction in canine AD. Canine AD shares many clinical and immunological similarities with its human counterpart. The similar distribution of clinical lesions and the importance of the epicutaneous route of allergen exposure provided the incentive to investigate the role of skin barrier impairments in canine AD. The purpose of this comparative review is to present the current evidence of barrier dysfunction in both human and canine AD.  相似文献
