Human utilization of the mulberry-silkworm interaction started at least 5,000 years ago and greatly influenced world history through the Silk Road. Complementing the silkworm genome sequence, here we describe the genome of a mulberry species Morus notabilis. In the 330-Mb genome assembly, we identify 128 Mb of repetitive sequences and 29,338 genes, 60.8% of(More)
BACKGROUND Wood is the end product of secondary vascular system development, which begins from the cambium. The wood formation process includes four major stages: cell expansion, secondary wall biosynthesis, lignification, and programmed cell death. Transcriptional profiling is a rapid way to screen for genes involved in these stages and their transitions,(More)
NAM/ATAF/CUC (NAC) family genes comprise one of the largest families of transcription factors in plant genomes and are widely expressed in developing woody tissues. In the present study, we constructed plant transformation vectors using the β-glucuronidase (GUS) reporter gene system and detected the promoter expression patterns derived from the PtNAC068 and(More)
Cry3 class toxins are used extensively for biological control of coleopteran larvae. We previously identified a peptide (PCx) from a phage display library that specifically binds Cx-cellulase from the midgut of Anoplophora glabripennis Motschulsky (Asian longhorn beetle) larvae. Here, we added a DNA fragment that encodes the peptide onto either end of the(More)
Populus euphratica Oliv., a species of the model woody plant genus Populus, is well known for its tolerance to salinity stress, the underlying mechanism of which is a research hotspot. Transient expression of fluorescent fusion proteins is commonly used for rapid assessment of gene functions and interactions, and thus would be useful to study the genes(More)
Wood formation is a complex developmental process primarily controlled by a regulatory transcription network. MicroRNAs (miRNAs) can modulate the expression of target genes involved in plant growth and development by inducing mRNA degradation and translational repression. In this study, we used a model of secondary vascular system regeneration established(More)
The plant hormone auxin is a central regulator of plant growth. TRANSPORT INHIBITOR RESPONSE 1/AUXIN SIGNALING F-BOX (TIR1/AFB) is a component of the E3 ubiquitin ligase complex SCF(TIR1/AFB) and acts as an auxin co-receptor for nuclear auxin signaling. The SCF(TIR1/AFB)-proteasome machinery plays a central regulatory role in development-related gene(More)
