This study examined the metabolic activity of pure cultures of five root pathogens commonly found in closed hydroponic cultivation systems (Phytophthora cryptogea (PC), Phytophthora capsici (PCP), Pythium aphanidermatum (PA), Fusariumoxysporum f.sp. radicis-lycopersici (FORL) and Fusarium solani (FS)) using sole carbon source utilisation in order to develop effective biocontrol strategies again...
Agathosma species, which are indigenous to South Africa, are also cultivated for commercial use. Recently growers experienced severe plant loss, and symptoms shown by affected plants suggested that a soilborne disease could be the cause of death. A number of Phytophthora taxa were isolated from diseased plants, and this paper reports their identity, mating type, and pathogenicity to young Agath...
The soil-borne species Aneurinibacillus migulanus (A. migulanus) strains Nagano and NCTC 7096 were shown to be potent biocontrol agents active against several plant diseases in agricultural forest ecosystems. Both produce the cyclic peptide gramicidin S (GS) that was described as main weapon inhibiting some gram-negative gram-positive bacteria fungus-like organisms along with production of bios...
NO has important physiological functions in plants, including the adaptative response to pathogen attack. We previously demonstrated that cryptogein, an elicitor of defence reaction produced by the oomycete Phytophthora cryptogea, triggers NO synthesis in tobacco. To decipher the role of NO in tobacco cells elicited by cryptogein, in the present study we performed a proteomic approach in order ...
در این مطالعه، روابط فیلوژنتیکی این گونه ها با استفاده از توالی سنجی نواحی هسته ای (فاصله ی ترانویسی شده ی داخلی، بتاتوبولین، پروتئین شوک حرارتی 90 و الیسیتین) و میتوکندریایی (زیرواحد یک سیتوکروم سی اکسیداز و زیرواحد یک اِن اِی-دی اِچ دهیدروژناز) مورد بررسی قرار گرفت. نتایج این پژوهش نشان داد که در تمامی درخت های فیلوژنتیکی رسم شده بر اساس توالی نواحی هسته ای و میتوکندریایی و درخت های برآیند نواحی...
Mitogen-activated protein kinase (MAPK) cascades are important signaling modules in eukaryotic cells. They function downstream of sensors/receptors and regulate cellular responses to external and endogenous stimuli. Recent studies demonstrated that SIPK and WIPK, two tobacco (Nicotiana spp.) MAPKs, are involved in signaling plant defense responses to various pathogens. Ntf4, another tobacco MAP...
Cryptogein is a proteinaceous elicitor secreted by Phytophthora cryptogea that can induce resistance to P. parasitica in tobacco plants. On the basis of previous computer modelling experiments, by site-directed mutagenesis a series of cryptogein variants was prepared with altered abilities to bind sterols, phospholipids or both. The sterol binding and phospholipid transfer activities correspond...
