A new color edge detector based on vector differences is proposed. The basic technique gives as its output the maximum distance between the vectors within a mask. When applied to scalar-valued images, the method reduces to the classic morphological gradient. The technique is relatively computationally efficient and can also be readily applied to other(More)
The disease take-all, caused by the fungus Gaeumannomyces graminis, is one of the most destructive root diseases of wheat worldwide. Breeding resistant cultivars is an effective way to protect wheat from take-all. However, little progress has been made in improving the disease resistance level in commercial wheat cultivars. MYB transcription factors play(More)
We constructed small RNA and degradome sequencing libraries to identify miRNAs and targets involved in tomato pedicel abscission, and confirmed their roles via quantitative real-time PCR. MicroRNAs (miRNAs) are endogenous small RNAs which play crucial negatively regulatory roles at both the transcriptional and post-transcriptional levels in plants; however,(More)
Abscission facilitates growth and reproduction and improves plant defenses against pathogens. This tightly regulated process is triggered by environmental cues and hormones such as ethylene and auxin. Because auxin is crucial for abscission, auxin response factors (ARFs) may play important roles in this process. Here, we examined changes in gene expression(More)
Solanum lycopersicum auxin response factor 10 (SlARF10) is post-transcriptionally regulated by Sl-miR160. Overexpression of a Sl-miR160-resistant SlARF10 (mSlARF10) resulted in narrower leaflet blades with larger stomata but lower densities. 35S:mSlARF10-6 plants with narrower excised leaves had greater water loss, which was in contrast to the wild type(More)
The necrotrophic fungus Rhizoctonia cerealis is a major pathogen of sharp eyespot that is a devastating disease of wheat (Triticum aestivum). Little is known about roles of MYB genes in wheat defense response to R. cerealis. In this study, TaRIM1, a R. cerealis-induced wheat MYB gene, was identified by transcriptome analysis, then cloned from resistant(More)
Phytohormones, such as auxin (IAA) and gibberellin (GA), are known to be essential for fruit development. We utilized GA-deficient (gib-3) and diageotropica (dgt) tomato mutants to elucidate the effects of single hormones in the pericarp. The application of IAA or GA, respectively, to gib-3 or dgt single mutants induced a significant morphological(More)
SlARF2a is expressed in most plant organs, including roots, leaves, flowers and fruits. A detailed expression study revealed that SlARF2a is mainly expressed in the leaf nodes and cross-sections of the nodes indicated that SlARF2a expression is restricted to vascular organs. Decapitation or the application of 6-benzylaminopurine (BAP) can initially promote(More)
Cancer is one of the leading causes of death worldwide; with many different types, it kills thousands of people every day. Various types of treatments have been developed to treat cancer, and new approaches that are currently under investigation include boron neutron capture therapy (BNCT) [1] and gad-olinium neutron capture therapy (GdNCT).
