“…Seeds of alfalfa ( Medicago sativa L.) Mesa variety and black seeded Simpson lettuce ( Lactuca sativa L.) were stirred in 4% ClONa solution for 30 min, rinsed with deionized water (DI) three times and kept in DI for 24 h. Subsequently, seeds were rolled in autoclaved wet germination paper towels, as described by Carrrillo-Castaneda et al 37 Ten drops of antimycotic/antibiotic solution (Sigma 5955) were added to the seeds before the paper was rolled. The rolls were put into Mason jars containing approximately 10 mL of DI, incubated in the dark for four days and exposed to light for one day.…”

The increased production and use of nanoparticles (NPs) has generated concerns about their impact on living organisms. In this study, nCu, bulk Cu, nCuO, bulk CuO, Cu(OH)2 (CuPRO 2005, Kocide 3000), and CuCl2 were exposed for 15 days to 10 day-old hydroponically grown lettuce (Lactuca sativa) and alfalfa (Medicago sativa). Each compound was applied at 0, 5, 10, and 20 mg/L. At harvest, we measured the size of the plants and determined the concentration of Cu, macro and microelements by using ICP-OES. Catalase and ascorbate peroxidase activity was also determined. Results showed that all Cu NPs/compounds reduced the root length by 49% in both plant species. All Cu NPs/compounds increased Cu, P, and S (>100%, >50%, and >20%, respectively) in alfalfa shoots and decreased P and Fe in lettuce shoot (>50% and >50%, respectively, excluding Fe in CuCl2 treatment). Biochemical assays showed reduced catalase activity in alfalfa (root and shoot) and increased ascorbate peroxidase activity in roots of both plant species. Results suggest that Cu NPs/compounds not only reduced the size of the plants but altered nutrient content and enzyme activity in both plant species.

“…Their ability to deplete iron from their surroundings makes it unavailable to pathogenic fungi, creating a competitive advantage (O'Sullivan and O'Gara, 1992;Loper and Henkels, 1999). Inoculation with siderophore-producing bacteria grown under iron limiting conditions has a positive effect on plant growth (Carrillo-Castaneda et al, 2002); however the potential role for a combination of several PGP mechanisms and not siderophore production alone cannot be discounted.…”

a b s t r a c tThere is a growing body of evidence that demonstrates the potential of various microbes to enhance plant productivity and yield in cropping systems. Realizing the potential of beneficial microbes requires an understanding of the role of microbes in growth promotion, particularly in terms of fertilization and disease control, the underlying mechanisms and the challenges in application and commercialization of plant growth-promoting (PGP) microbes. This review focuses specifically on the use of PGP microbes in the cotton industry and summarizes the commercial bioinoculant products currently available for cotton; highlighting factors that must be considered for future development of PGP microbial products for the cotton industry. Given the paucity of information on beneficial microbes for cotton production systems in comparison to those for other cropping systems (e.g. legumes and grains), a snapshot of the current research is critical in light of the increased interest in cotton inoculants, mainly in developing countries such as India, and the overall increased interest in PGP applications as part of promoting sustainable agriculture.
