Rhizoctonia solani, Cinnamomum cassia, Nigella sativa, Pectinases and protease, Carboxymethyl cellulase, Docking Abstract: The present study evaluated the ability of different extracts of cinnamon and black cumin seeds to inhibit the growth of the phytopathogenic fungus Rhizoctonia solani and its extracellular cell wall degrading enzymes. Concentrations of 300 and 450 ppm of methylene chloride and hexane extracts of cinnamon completely inhibited the growth of R. solani after 72 hours of incubation at 25±1°C in vitro. Methylene chloride or hexane extracts of black cumin seeds at 4000 ppm after 72 hours inhibited the growth of R. solani by 37 and 39% respectively. Moreover, black cumin seed hexane extract at 2000 ppm inhibited 55% and 38% of the activity of pectin lyase (PL) and polygalacturonase (PG) respectively. In addition, the methanolic extract of black cumin seeds at 2000 ppm exhibited a significant reduction of exo-protease activity (74.8%). GC-MS analysis results showed that linoleic acid is the main component of the fixed oil fraction of black cumin seed hexane extract while (E)-cinnamaldehyde is the main component in both hexane and methylene chloride extracts of cinnamon. HPLC-MS analysis of black cumin seeds methanolic extract showed that amentoflavone, was the main component. Docking was used to identify the major component interaction with pectin lyase A and exo-protease.

: Accelerating global warming and water scarcity and improving water use efficiency are considered essential factors for achieving adequate crop development and productivity. Therefore, the authors targeted the use of arbuscular mycorrhizal fungi (AMF) and Pseudomonas fluorescens (Ps1) for improving growth, productivity, and water use efficiency of broccoli plants ( Brassica olercea L. var. italica , cv. Belstar F 1 ) under various irrigation regimes i.e., 50, 75, and 100% of crop evapotranspiration (ETc). Two greenhouse experiments were carried out in clayey soil. The combined inoculation of endomycorrhizae and Ps. fluorescens (Ps1) improved water use efficiency and consequently vegetative growth and yield. Under the applied irrigation regime 75% ETc of broccoli inoculated with both endomycorrhizae and Ps. fluorescens (Ps1) showed higher head weight (616 and 647 gram) than those grown under the irrigation regime 75% ETc combined with endomycorrhizae
:加速全球变暖和缺水以及提高用水效率被认为是实现充分作物发展和生产力的基本因素。因此，作者瞄准了利用丛枝菌根真菌(AMF)和荧光假单胞菌(Ps1)来提高西兰花(Brassica olercea L. var. italica, cv.)的生长、生产力和水分利用效率。在不同的灌溉制度下，即50%、75%和100%的作物蒸散量(等)。在粘性土壤中进行了两个温室试验。联合接种内生菌根和荧光ps (Ps1)提高了水分利用效率，从而提高了营养生长和产量。75% ETc同时接种内生菌根和荧光ps (Ps1)的西兰花在灌水条件下的穗重(616和647 g)高于75% ETc同时接种内生菌根的西兰花
