Leaf morphology in maize is regulated by developmental patterning along three axes: proximodistal, mediolateral, and adaxial-abaxial. Maize contains homologues of many genes identified as regulators of leaf development in other species, but their relationship to the natural variation of leaf shape remains unknown. In this study, quantitative trait loci(More)
The objective of this study is to develop techniques for assessing and analysing land desertification in Yulin of Northwest China, as a typical monitoring region through the use of remotely sensed data and geographic information systems (GIS). The methodology included the use of Landsat TM data from 1987, 1996 and 2006, supplemented by aerial photos in(More)
Halophytes can grow under a high salinity condition. Similar to glycophytes, their salt-tolerance possesses a high genetic complexity. There are many morphological and physiological studies on halophytes but very little information is at molecular level why they are salt-tolerant. Limonium sinense is a salt-secreting halophyte and can excretes salts by(More)
Associations were analysed between polymorphisms of the growth hormone gene (GH-MspI) (localized in intron 3) and milk production traits of Beijing Holstein cows (a total of 543 cows). Polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method was used for identification of various geno-types. Frequencies of genotypes were 0.77,(More)
Microsatellites have proved to be useful polymorphic markers for the analysis of genetic diversity. Microsatellite based studies in livestock have mainly concentrated on pig, cattle and sheep, and there are now more than a thousand cattle microsatellite markers to choose from (Barendse et al. 1994; Kappes et al. 1997). Genotyping of cattle can be done on(More)
Maize architecture is a major contributing factor to their high level of productivity. Maize varieties with an erect-leaf-angle (LA) phenotype, which increases light harvesting for photosynthesis and grain-filling, have elevated grain yields. Although a large body of information is available on the map positions of quantitative trait loci (QTL) for LA,(More)
The highly pathogenic avian influenza (HPAI) H5N1 outbreak at Qinghai Lake, China, in 2005 caused the death of over 6,000 migratory birds, half of which were Bar-headed Geese Anser indicus. Understanding the movements of this species may inform monitoring of outbreak risks for HPAI viruses; thus, we investigated the movement patterns of 29 Bar-headed Geese(More)
Endmember extraction and spectral unmixing is a very challenging task in multispectral/hyperspectral image processing due to the incompleteness of information. In this paper, a new method for endmember extraction and spectral unmixing of hyperspectral images is proposed, which is called as minimum distance constrained nonnegative matrix factorization(More)
Algorithms based on reflectance band ratios and first derivative have been developed for the estimation of chlorophyll a and carotenoid content of rice leaves by using airborne hyperspectral data acquainted by Pushbroom Hyperspectral Imager (PHI). There was a strong R680/R825 and chlorophyll a relationship with a linear relationship between the ratio of(More)
Bone is one of the most frequent targets of small cell lung cancer (SCLC) metastasis, but the molecular mechanism remains unclear. β3-integrin plays an important role in invasion of various kinds of tumors. Yet, its role in bone-metastasis of SCLC is still unknown. In this study, we first examined the expression of β3-integrin in SBC-5 and SBC-3 cells by(More)
