RNA sequencing can simultaneously identify exonic polymorphisms and quantitate gene expression. Here we report RNA sequencing of developing maize kernels from 368 inbred lines producing 25.8 billion reads and 3.6 million single-nucleotide polymorphisms. Both the MaizeSNP50 BeadChip and the Sequenom MassArray iPLEX platforms confirm a subset of high-quality(More)
Maize plant height is closely associated with biomass, lodging resistance and grain yield. Determining the genetic basis of plant height by characterizing and cloning plant height genes will guide the genetic improvement of crops. In this study, a quantitative trait locus (QTL) for plant height, qPH3.1, was identified on chromosome 3 using populations(More)
Argonaute (AGO) proteins play a key role in regulation of gene expression through small RNA-directed RNA cleavage and translational repression, and are essential for multiple developmental processes. In the present study, 17 AGO genes of maize (Zea mays L., ZmAGOs) were identified using a Hidden Markov Model and validated by rapid amplification of cDNA ends(More)
MicroRNAs (miRNAs) are critical post-transcriptional modulators of gene expression involving in plant responses to abiotic stress. However, the regulation of miRNA in the morphological response to waterlogging is poorly understood in maize. In this study, we detected miRNAs and their targets that expressed in waterlogged crown roots of maize seedlings in(More)
PREMISE OF THE STUDY In a warming climate, boreal trees may have adjusted their growth strategy (e.g., onset and coordination of growth among different organs such as stem, shoot, and foliage, within and among species) to cope with the extended growing seasons. A detailed investigation into growth of different organs during a growing season may help us(More)
In this paper a method of image enhancement based on rough-set and genetic algorithm (GA) is developed.The application of rough-set on image enhancement is different from traditional methods. According to the class attribute of rough-set, we can divide the image into the marginal zone and non-marginal zone, and then enhance them separetely. In the process(More)
PREMISE OF THE STUDY Climate warming might have resulted in altered initiation and termination dates of stem xylem growth in boreal stands. A systematic understanding of intra-annual xylem formation is thus needed for precise simulation of future growth in the context of sustainable forest management. METHODS A recently developed novel microsampling(More)
Immediate phenotypic variation and the lagged effect of evolutionary adaptation to climate change appear to be two key processes in tree responses to climate warming. This study examines these components in two types of growth models for predicting the 2010-2099 diameter growth change of four major boreal species Betula papyrifera, Pinus banksiana, Picea(More)
Small RNAs are essential for a variety of cellular functions. Argonaute (AGO) proteins are associated with all of the different classes of small RNAs, and are indispensable in small RNA-mediated regulatory pathways. AGO proteins have been identified in various types of stem cells in diverse species from plants and animals. This review article highlights(More)
Cognitive evoked potential (CEP) is an important description of brain cognitive function. At present average CEP of several measurements is used to extract CEP. However, as the latency of CEP varies at a large area, averaging brings a serious distort of shape and amplitude. So, nonlinear dynamic extraction of CEP using one or a few trials has been widely(More)
