Effective plant defense strategies rely in part on the perception of non-self determinants, so-called microbe-associated molecular patterns (MAMPs), by transmembrane pattern recognition receptors leading to MAMP-triggered immunity. Plant resistance against necrotrophic pathogens with a broad host range is complex and yet not well understood. Particularly, it is unclear if resistance to necrotro...

Biological Nitrogen fixation is one of the two sources of nitrogen (N). Most nitrogen fixation in agriculture takes place in the Fabaceae family which can form symbiotic relationships with Rhizobium spp. if it is present in the soil. This study reexamines the effect that nitrogen (N) application has on nodulation number on the rooting zone of two small seeded legumes, alfalfa (Medicago sativa L...

Cucumber plants (Cucumis sativus L.) were grown under controlled conditions and fumi­ gated with either 0 3, diluted automobile exhaust or a combination of both. The ratio of variable to maximum chlorophyll fluorescence (FJFm) was estimated as a measure of PSII activity Activities of the enzymes catalase, glutathione reductase and guaiacol-dependent peroxidase and contents of the antioxidants a...

Perception of microbe-associated molecular patterns (MAMPs) elicits transcriptional reprogramming in hosts and activates defense to pathogen attacks. The molecular mechanisms underlying plant pattern-triggered immunity remain elusive. A genetic screen identified Arabidopsis poly(ADP-ribose) glycohydrolase 1 (atparg1) mutant with elevated immune gene expression upon multiple MAMP and pathogen tr...

Establishment of arbuscular mycorrhizal symbiosis in plant roots can affect plant physiological and morphological characteristics and may induce tolerance to heavy metals in plants grown in polluted soils; therefore, it can play an important role in phytoremediation. In present study, to investigate the effect of mycorrhizae on alfalfa growth and Pb uptake, a factorial experiment was designed w...

Three seasonal ornamental plants, namely Petunia hybrida, Callistephus chinensis and Impatiens balsamina, were tested for their response to inoculation with mixed indigenous AM culture when grown on a marginal wasteland amended with organic matter. Subsequently, the treatments consisting of AM inoculations were compared with those consisting of recommended chemical fertilizers in terms of growt...
