Geminiviridae consists of a large group of single-stranded DNA viruses that cause tremendous losses worldwide. Frequent mixed infection and high rates of recombination and mutation allow them to adapt rapidly to new hosts and overcome hosts’ resistances. Therefore, an effective strategy able to confer plants with resistance against multiple begomoviruses is(More)
BACKGROUND Tall fescue (Festuca arundinacea Schreb) is a major cool season forage and turf grass species grown in the temperate regions of the world. In this paper we report the generation of a tall fescue expressed sequence tag (EST) database developed from nine cDNA libraries representing tissues from different plant organs, developmental stages, and(More)
CpG repression in RNA viruses has been known for decades, but a reasonable explanation has not yet been proposed to explain this phenomenon. In this study, we calculated the CpG odds ratio of all RNA viruses that have available genome sequences and analyzed the correlation with their genome polarity, base composition, synonymous codon usage, phylogenetic(More)
In the first reaction specific for proanthocyanidin (PA) biosynthesis in Arabidopsis thaliana and Medicago truncatula, anthocyanidin reductase (ANR) converts cyanidin to (−)-epicatechin. The glucosyltransferase UGT72L1 catalyzes formation of epicatechin 3′-O-glucoside (E3′OG), the preferred substrate for MATE transporters implicated in PA biosynthesis in(More)
The liver is the most frequent site of metastasis in colorectal cancer (CRC), in which long noncoding RNAs (lncRNAs) may play a crucial role. In this study, we performed a genome-wide analysis of lncRNA expression to identify novel targets for the further study of liver metastasis in CRC. Samples obtained from CRC patients were analyzed using Arraystar(More)
Cotton (Gossypium spp.) is an important economic crop and there is obvious heterosis in cotton, fertility has played an important role in this heterosis. However, the genes that exhibit critical roles in anther development and fertility are not well understood. Here, we report an acyl-CoA N-acyltransferase (EC2.3; GhACNAT) that plays a key role in anther(More)
Transcription activator-like effectors (TALEs) are a class of sequence-specific DNA-binding proteins that utilize a simple and predictable modality to recognize target DNA. This unique characteristic allows for the rapid assembly of artificial TALEs, with high DNA binding specificity, to any target DNA sequences for the creation of customizable(More)
A cDNA sequence that encodes a peptide with similarity to known tropinone reductases (TR) was cloned from Dendrobium nobile Lindl. The full coding region of the gene (DnTR1) is 804 bp in length which encodes a putative peptide consisting of 268 amino acids. Phylogenetic analysis showed that DnTR1 was a novel member of the TR family and evolutionarily(More)
Knowing how climate change affects the population dynamics of insect pests is critical for the future of integrated pest management. Rising winter temperatures from global warming can drive increases in outbreaks of some agricultural pests. In contrast, here we propose an alternative hypothesis that both extremely cold and warm winters can mismatch the(More)
Cotton plants engineered for resistance to the herbicides, glyphosate or glufosinate have made a considerable impact on the production of the crop worldwide. In this work, embryogenic cell cultures derived from Gossypium hirsutum L. cv Coker 312 hypocotyl callus were transformed via Agrobacterium tumefaciens with the rice cytochrome P450 gene, CYP81A6(More)
