In some species, a crucial role has been demonstrated for the seed endosperm during germination. The endosperm has been shown to integrate environmental cues with hormonal networks that underpin dormancy and seed germination, a process that involves the action of cell wall remodeling enzymes (CWREs). Here, we examine the cell wall architectures of the endosperms of two related Brassicaceae, Ara...

Cladospirone bisepoxide (1), a novel metabolite, was isolated from cultures of a fungus which was characterized as a coelomycete by the formation of pycnidia. By optimization of media and fermentation conditions, a titer of up to 1.5 g/liter on shake level and 1.16 g/liter on bioreactor scale could be achieved. The isolation of the compound was performed by solvent extraction of the culture bro...

Twelve essential oils from Mediterranean aromatic plants were tested for their phytotoxic activity, at different doses, against the germination and the initial radicle growth of seeds of Raphanus sativus, Lactuca sativa and Lepidium sativum. The essential oils were obtained from Hyssopus officinalis, Lavandula angustifolia, Majorana hortensis, Melissa officinalis, Ocimum basilicum, Origanum vul...

Bu çalışmada Konya’da bulunan yatak kapasiteleri 27-600 kişi arasında değişen 10 hastanenin atıksuyundan yaz ve kış dönemlerinde örnekler alınarak fizikokimyasal özellikleri belirlenmiş Vibrio fischeri, Daphnia magna, Lepidium sativum toksisite testleri ile ekotoksikolojik etkisi belirlenmiştir. Hastane atıksularının pH, elektriksel iletkenlik, askıda katı madde toplam organik karbon parametrel...

Nanoparticles (NPs) are commonly used, and concerns about their possible adverse effects are being voiced as well. However, little is known about the fates of NPs released to the environment. The aim of the study was to (i) evaluate the ability of Sinapis alba and Lepidium sativum plants to take up platinum nanoparticles (Pt-NPs) and translocate them to aboveground organs, (ii) compare the accu...

Some saprobe fungi (Phlebia radiata, Trametes versicolor, Coriolopsis rigida, Pycnoporus cinnabarinus, Fomes sclerodermus or Pleurotus pulmonarius) were able to bioconvert the ethyl acetate fraction (DEAF) and the corresponding aqueous exhausted fraction (EAF) of dry olive mill residue (DOR), reducing their phytotoxicity on Lepidium sativum seeds. Large amount of hydroxytyrosol together with ot...

Comparative biology includes the comparison of transcriptome and quantitative real-time RT-PCR (qRT-PCR) data sets in a range of species to detect evolutionarily conserved and divergent processes. Transcript abundance analysis of target genes by qRT-PCR requires a highly accurate and robust workflow. This includes reference genes with high expression stability (i.e., low intersample transcript ...
