Nutritional enhancement of rice for human health: The contribution of biotechnology

Micronutrient malnutrition is widespread, especially in poor populations across the globe where daily caloric intake is confined mainly to staple cereals. Rice, which is a staple food for over half of the world's population, is low in bioavailable micronutrients required for the daily diet. Improvements of the plant-based diets are therefore critical and of high economic value in order to achieve a healthy nutrition of a large segment of the human population. Rice grain biofortification has emerged as a strategic priority for alleviation of micronutrient malnutrition. Nutritional enhancement of crops through conventional breeding is often limited by the low genetic variability for required dietary micronutrient levels. In this case, biotechnology strategies offer effective and efficient perspectives. In this review, we discuss genetic engineering approaches that have been successful in the nutritional enhancement of rice endosperm. These advancements will make substantial contributions to crop improvement and human nutrition. Their practical application, however, also demands visionary changes in regulatory policies and a broader consumer acceptance.     

Abstracts of papers and posters presented at the 33rd conference of the New Zealand society for Parasitology,at Massey University,Palmerston North, 24 October 2006

Abstract

Eight species of Recent Braohiopoda dredged from the fiords of south-western New Zealand in 1946 included first records for Fiordlarrd of Crania, Amphithyris, and Liothyrella. Amphithyris richardsonae n.sp. is described from a live-collected individual from 74 m, Long Sound, Preservation Inlet; it differs from A. buckmani Thomson and A. hallettensis Foster in shape, attachment, and details of ornament. Ventml valves fTom 101 m, Dagg Sound, characterised by coarse punctation and an ornament of hollow spines are treated as Platidiidae genus and species indeterminate.     

The ultrastructure of pinealocytes in the golden mole (Amblysomus hottentotus) with special reference to the granular vesicles

Summary The ultrastructure of the pinealocytes of the golden mole (Amblysomus hottentotus), a blind subterranean mammal living in complete darkness, was examined and compared with that of pinealocytes of other mammals. On the basis of the presence of granular vesicles and glycogen granules, only one population of pinealocytes was found. Large mitochondria, ribosomes, lipid inclusions and scarce lysosomes were observed in the perikaryon. Numerous glycogen granules, often forming typical accumulations, were frequently found to be associated with typical vacuoles. An extraordinary large number of granular vesicles is characteristic of the golden mole pinealocyte. Phenomena of excretion of compound(s) stored in the granular vesicles were identified. Morphologically this is characterized by dissociation of its granular core in situ while its limiting membrane is preserved. The physiological significance of the secretory process characterized by the formation of these granular vesicles is discussed.A portion of these observations were presented at the International Symposium on the Pineal Gland, Jerusalem, Israel, November 14–17, 1977     

秦岭川金丝猴的母系投入与生殖性别偏倚

雌性灵长类为获得更高的投入收益比,会调整其对不同性别后代的母系投入策略,并主要表现为针对某一性别尽可能多的生育或对某一性别的幼崽付出更多的母系照顾。雄性质量模型(MaleQualityModel,MQ)和栖息地资源竞争模型(LocalResourceCompetitionModel,LRC)分别将这种现象发生的机制解释为物种对性选择压力和资源竞争压力的回应。本研究通过对一个秦岭川金丝猴群生育行为连续四年的观察,发现该种群新生雄性幼崽的数量多于雌性幼崽,种群的次级性比存在偏离(♀∶♂=1∶1.71)。通过对不同社会单元的等级与雄性出生率的分析,发现两者之间存在一元线性关系(PM=-0.4918MDI 0.9329)(t=-1.879,df=24,P=0.073<0.10,R2=0.1331),各社会单元内新生雄猴占所有新生幼猴的比例会随着该单元社会等级的降低而升高,呈现PMH相似文献   

The novel primers for sex identification in the brown eared-pheasant and their application to other species

We designed a pair of primers for sex identification in the brown eared-pheasant (Crossoptilon mantchuricum) based on the mechanism of PCR amplification of CHD fragments, and identified the number of products. The new primers were considered to have more sensitivity than P2/P8, and cross-species application indicated that they can also be used for sex identification in other species of Phasianidae and Passeriformes.     

Using probability of occurrence to assess potential interaction between wind farms and a residual population of golden eagle Aquila chrysaetos in NW Spain

We evaluate the areas with potential negative impacts in a golden eagle population derived of the development of wind farms. At present, the entire golden eagle Galician population (5–6 pairs) is located within an area of about 2,000 km². Grid squares of 10 × 10 km UTM in the province were scored for current and future wind turbine density and probability of occurrence of golden eagle. This probability was obtained using cartographic models of habitat selection for two different historic periods. Potential risk index (PRI) was calculated for each grid square by multiplying the wind turbine density score by the probability of occurrence score. With the PRIs obtained a cartographic model of potential impact of wind farms on the golden eagle population was constructed. No significant correlation was observed between current wind turbine density and the probability of occurrence of golden eagle. A significant positive correlation was observed between current and future wind turbine density and the probability of occurrence of golden eagle. The areas with highest potential risk are eastern and the central mountains of Ourense where the species breeds. The risk model presented could be applied to future wind farm proposals and monitor potential interactions of golden eagles with wind farms in the Province of Ourense.     

黑颈长尾雉的巢址选择

2004年至2005年,在广西百色岑王老山自然保护区对黑颈长尾雉(Syrmaticus humiae)的巢址选择进行了研究。野外工作中共发现5巢,其中3巢在针叶林中,2巢在灌草丛中。结果表明,黑颈长尾雉的巢都是选择在向阳的东南坡且位于坡的下位,靠近林缘、水源和林间小道。对巢址10 m×10 m和1 m×1 m植被样方不同层次盖度作统计发现,黑颈长尾雉巢址选择更多的依赖于灌木层和草本层的盖度。
