Colorectal cancer (CRC) recurrence is often attributable to circulating tumor cells and/or cancer stem cells (CSCs) that resist to conventional therapies and foster tumor progression. Isothiocyanates (ITCs) derived from Brassicaceae vegetables have demonstrated anticancer effects in CRC, however little is known about their effect in CSCs and tumor initiation properties. Here we examined the eff...

The analysis of the Arabidopsis genome revealed evidence of three ancient polyploidy events in the evolution of the Brassicaceae, but the exact phylogenetic placement of these events is still not resolved. The most recent event is called the At-alpha (alpha) or 3R, the intermediate event is referred to as the At-beta (beta) or 2R, and the oldest is the At-gamma (gamma) or 1R. It has recently be...

BACKGROUND AND AIMS Brassicaceae, with nearly 340 genera and more than 3350 species, anchors the low range of angiosperm genome sizes. The relatively narrow range of DNA content (0.16 pg < 1C < 1.95 pg) was maintained in spite of extensive chromosomal change. The aim of this study was to erect a cytological and molecular phylogenetic framework for a selected subset of the Brassicacae, and use t...

Establishment of morphological novelties has contributed to the enormous diversification of floral architecture. One such novelty, flower monosymmetry, is assumed to have evolved several times independently during angiosperm evolution. To date, analysis of monosymmetry regulation has focused on species from taxa where monosymmetry prevails, such as the Lamiales and Fabaceae. In Antirrhinum maju...

The genetic mechanisms regulating dry fruit development and opercular dehiscence have been identified in Arabidopsis thaliana. In the bicarpellate silique, valve elongation and differentiation is controlled by FRUITFULL (FUL) that antagonizes SHATTERPROOF1-2 (SHP1/SHP2) and INDEHISCENT (IND) at the dehiscence zone where they control normal lignification. SHP1/2 are also repressed by REPLUMLESS ...

DNA barcode sequences are accumulating in large data sets. A barcode is generally a sequence larger than 1000 base pairs and generates a computational burden. Although the DNA barcode was originally envisioned as straightforward species tags, the identification usage of barcode sequences is rarely emphasized currently. Single-nucleotide polymorphism (SNP) association studies provide us an idea ...

گیاه sameraria stenophylla به عنوان گونه جدیدی از شرق ایران گزارش می شود. این گونه به سادگی با داشتن گلبرگ های بلند و سرنیزه ای بودن قاعده برگ های ساقه ای از گونه مجاور خود یعنی sameraria elegans قابل تفکیک است. نقشه پراکنش این گونه و نزدیکترین خویشاوند آن به همراه تصویری از این گونه ارائه می شود.

tissue culture is an attractive alternative for plant propagation. micropropagation is a technique to ensure a constant and uniform source of ornamental plants. matthiola incana is an important ornamental species mainly cultivate by seed. matthiola incana seeds were germinated on solid ms medium without plant growth regulators. shoot proliferation and root formation are possible using kinetin (...

The flower is essential for sexual reproduction of flowering plants and has been extensively studied. However, it is still not clear how many genes are expressed in the flower. Here, we performed RNA-seq analysis as a highly sensitive approach to investigate the Arabidopsis floral transcriptome at three developmental stages. We provide evidence that at least 23, 961 genes are active in the Arab...
