Cyclotides are plant peptides comprising a circular backbone and three conserved disulfide bonds that confer them with exceptional stability. They were originally discovered in Oldenlandia affinis based on their use in traditional African medicine to accelerate labor. Recently, cyclotides have been identified in numerous plant species of the coffee, violet, cucurbit, pea, potato, and grass fami...
Due to widespread industrial use, chromium (Cr) is considered a hazardous environmental pollutant. It is known to inhibit plant growth and development. The present study provides the evidence of the phytotoxicity of this metal on the pea (Pisum sativum L. cv Azad) plants. The plants of pea (Pisum sativum L.) were grown in refined sand under different concentrations i.e. 0.05, 0.1, 0.2, 0.3 and ...
Endophytic bacteria are critical for plant growth and health. However, compositional and functional responses of bacterial endophyte communities towards agricultural practices are still poorly understood. Hence, we analyzed the influence of fertilizer application and mowing frequency on bacterial endophytes in three agriculturally important grass species. For this purpose, we examined bacterial...
Arbuscular mycorrhizae (AM) and Plant Growth Promoting Rhizobacteria (PGPR) associations are integral and functioning parts of plant roots. These associations have a basic role in root uptake efficiency as well as improvement of plant growth in degraded environments including heavy metals contaminated soils. This study was conducted to evaluate the effects of heavy metal-resistant soil microbe'...
ATCase carries out the first committed step in de novo pyrimidine nucleotide biosynthesis in plants, and its activity is regulated via classical end-product inhibition by UMP or its products (Lovatt and Cheng, 1984). As an important first step in understanding the mechanisms by which plant ATCase expression is regulated, we have cloned a pea (Pisum sativum L.) ATCase gene. This appears to be th...
bauer, 1996). Many pea diseases common in production areas affect root growth and function, thereby limiting Root growth is an important component of plant growth but has productivity (Kraft and Pfleger, 2001, p. 67). Tolerance received little attention by plant breeders because of difficulties associto many root diseases has been attributed to rapid root ated with root observation. Improved ro...
Leguminosae, Lathyrus sativus, Phytoalexin, 6a-Hydroxypterocarpan, Pisatin Lathyrus sativus was investigated for the nature of its phytoalexin response with the result that leaflets, im mature pods, and seeds were induced to produce 6a-hydroxy-3-methoxy-8,9-methylenedioxypterocarpan (pisatin). Evidence is presented for the metabolism of pisatin, by the wound pathogen Botrytis cinerea, to a phe...
In order to evaluate the effect of seed priming on some effective physiological parameters on seed germination of pea (Pisum sativum L.) under chilling stress, a factorial experiment was conducted in completely randomized design with four replications. Treatments were consisted of priming treatments (hydropriming, halopriming, osmopriming and no priming) and temperature (3, 6, 9, 12 and 15 ˚c)....
Mammalian herbivores profoundly influence plant-dwelling insects [1]. Most studies have focused on the indirect effect of herbivory on insect populations via damage to the host plant [2,3]. Many insects, however, are in danger of being inadvertently ingested during herbivore feeding. Here, we report that pea aphids (Acyrthosiphon pisum) are able to sense the elevated heat and humidity of the br...
Endophytic fungi are plant symbionts living asymptomatically within plant tissues. Neotyphodium spp., which are asexual vertically transmitted systemic fungal endophytes of cool-season grasses, are predicted to be plant mutualists. These endophytes increase host plant resistance to environmental stresses and/or increase the production of alkaloid-based herbivore deterrents. The ubiquity of this...
