The transcription factors C-repeat binding factors/dehydration-responsive element binding proteins (CBFs/DREBs) control the expression of many stress-inducible genes in Arabidopsis. A cDNA clone, designated GhDREB1, was isolated from cotton (Gossypium hirsutum) by cDNA library screening. Northern blot analysis indicated that mRNA accumulation of GhDREB1 was(More)
* Zinc finger proteins are a superfamily involved in many aspects of plant growth and development. However, CCCH-type zinc finger proteins involved in plant stress tolerance are poorly understood. * A cDNA clone designated Gossypium hirsutum zinc finger protein 1 (GhZFP1), which encodes a novel CCCH-type zinc finger protein, was isolated from a salt-induced(More)
The locus control region (LCR) of the human red and green visual pigment genes is critical for the formation of functional red and green cones in the retina. A 37-bp core of the LCR is perfectly conserved among mammals and binds specific retinal nuclear proteins. Here, we employed a yeast one-hybrid screen of an adult retinal cDNA library to clone and(More)
MicroRNAs (miRNAs) have emerged as a class of regulators of gene expression through posttranscriptional degradation or translational repression in living cells. Increasing evidence points to the important relationship between miRNAs and environmental stress responses, but the regulatory mechanisms in plants are poorly understood. Here, we found that(More)
The nuclear factor Y (NF-Y), which is a ubiquitous transcription factor found in eukaryotes, is composed of three distinct subunits, namely, NF-YA, NF-YB, and NF-YC. Here, we firstly characterized the detailed function of the Arabidopsis NFYA1 factor. It is found that the 35S::AtNFYA1-overexpressed lines were hypersensitive to salt stress and Abscisic acid(More)
Currently, the molecular regulation mechanisms involved in the early development of maize brace root are poorly known. To gain insight into the transcriptome dynamics that are associated with its development, genome-wide gene expression profiling was conducted by Solexa sequencing (Illumina Inc., San Diego, CA, USA). More than five million tags were(More)
Plants vary significantly in their ability to tolerate low temperatures. The CBF/DREB1 cold response pathway has been identified in many plant species and plays a pivotal role in low temperature tolerance. Here, we show that GhDREB1 is a functional homologue and elevates the freezing, salt and osmotic stress tolerance of transgenic Arabidopsis. The(More)
Being poikilothermic and sessile organisms, plants have to respond quickly to changing environmental cues, and a higher order of gene regulation is required. The significance of nucleocytoplasmic transport via importinalpha and importinbeta (alpha/beta) has been exhibited in a wide spectrum of biological processes. However, most of these receptors have not(More)
To characterize the microRNAs that contribute to the development of brace root, Solexa high-throughput sequencing of three libraries derived from tissues of node (N), nodes with just-emerged brace roots (NR), and nodes with just-emerged brace roots after IAA treatment (NRI) was performed. Total 650,793, 957,303 and 1,082,948 genome-matched unique reads were(More)
Spa2 is an important component of the multiprotein complex polarisome, which is involved in the establishment, maintenance, termination of polarized cell growth and is important for defining tip growth of filamentous fungi. In this study, we isolated an insertional mutant of the rice blast fungus Magnaporthe oryzae that formed smaller colony and conidia(More)
