Cell wall degrading enzymes in Orobanche aegyptiaca and its host Brassica campestris

Physiologia Plantarum, 1993
Activities of the cell‐wall degrading enzymes cellulase (EC 3. 2. 1. 4). poly‐galacturonase (EC 3. 2. 1. 15) and xylanase (EC 3. 2. 1. 8), and also that of protease (EC 3. 4. 21. 14) have been determined in the parasite Orobanche aegyiptiaca Pers. and in the roots of infected and control host plants of Brassica campestris L. var. rapa Hartm.

Inhibitors of polygalacturonase in calli of Orobanche aegyptiaca

Phytochemistry, 1997
The presence of at least three distinct polygalacturonases (PGase) in callus of Orobanche was demonstrated. The PGase activity is labile and at pH 4.5 does not require activation by cations. It can be partially purified on Biogel P 100 columns and can be resolved by PAGE into several bands.

In Vitro Culture of Orobanche aegyptiaca

Annals of Botany, 1991
Calli derived from seedlings of the parasitic plant Orobanche aegyptiaca were grown on enriched nutrient agar. Growth was enhanced by the addition of 0.1 mg l -1 NAA and 5% coconut milk. The calli developed two kinds of elongated protrusions: thin ones which resemble the young root radicle and thick ones which resemble the adventitious roots of ...

Control of Orobanche aegyptiaca and O. ramosa in potato

Crop Protection, 2001
Abstract Potato ( Solanum tuberosum ) is a susceptible host of the root holoparasites Orobanche aegyptiaca and Orobanche ramosa in the Mediterranean region, and suffers severe yield losses due to high levels of field infestations. Sulfonylurea and imidazolinone herbicides are selective acetolactate synthase-inhibiting herbicides that have been ...

OROBANCHE AEGYPTIACA CONTROL IN TOMATO WITH SULFONYLUREA HERBICIDES

Acta Horticulturae, 2003
Orobanche spp. are root holoparasitic that cause severe damage to vegetable and field crops worldwide. O. aegyptiaca is common throughout Israel and parasitizes a wide range of crops, including processing tomatoes. Efficacy of O. aegyptiaca control and selectivity of 4 tomato varieties to sulfosulfuron (Monitor, Monsanto, 75% WG), rimsulfuron (Titus ...

Purification of pectin methylesterase from Orobanche aegyptiaca

Phytochemistry, 1996
The purification of pectin methylesterase by the use of acrylamide gel electrophoresis followed by electro-elution and Biogel column chromatography is described. Antibodies were prepared against the purified enzyme and their specificity tested against crude extracts of Orobanche calli and purified enzyme.

Development of in-vitro seed germination assay for Orobanche aegyptiaca Pers. L. to assess the Mustard-Orobanche interaction

Journal of Oilseeds Research, 2023
Orobanche aegyptiaca Pers. L. has emerged as a serious constraint to the mustard cultivation in India. Orobanche seed germination requires induction by stimulants present in root exudates of mustard plants. An efficient In-vitro assay is important for understanding the Mustard-Orobanche interactions and evaluation of germplam lines of Indian mustard ...

Pectin methylesterase in calli and germinating seeds of Orobanche aegyptiaca

Phytochemistry, 1993
Abstract The presence and secretion of pectin methylesterase was compared in infective calli and seedlings of Orobanche aegyptiaca and of O.

Differential response of pea (Pisum sativum) to Orobanche crenata, Orobanche foetida and Phelipanche aegyptiaca

Crop Protection, 2012
Several broomrape species including Orobanche crenata, Orobanche foetida and Phelipanche aegyptiaca are reported to infect various grain and forage legumes in the Mediterranean and West Asia. Pea (Pisum sativum) is severely damaged by O. crenata, but there are no reports on O. foetida or P. aegyptiaca infection.

Bacterial inhibition ofOrobanche aegyptiacaandOrobanche cernuaradical elongation

Biocontrol Science and Technology, 2010
Abstract The ability of different bacteria to inhibit Orobanche radical elongation was examined. Seeds of Orobanche aegyptiaca Pers. and O. cernua Loefl. were induced to germinate with the Growth Regulator GR24 in the presence or absence of test bacterium.
