In order to study the effects of biofertilizers on yield quantity and quality of Capsicum annuum L., an experiment was conducted in completely randomized block design with three replications in 2011. All plants were treated before transplanting in pots in greenhouse condition by biological fertilizers including nitroxin and biophosphates. Treatments included 3 concentrations of nitroxin (1:3, 1...

Agrobacterium tumefaciens B-6 and T-37 strains, inoculated into Nicotiana glauca, N. langsdorffii, and their interspecific hybrid, which forms genetic (spontaneous) tumors as well, initiate amorphous tumors from the B-6 strain and organoid tumors (aberrant roots, stems, and buds) from the T-37 strain. In the hybrid, the critical point was to induce crown gall tumors at the site of wounding and ...

MicroRNAs are 19- to 24-nt-long single-stranded RNAs that are crucial regulators of gene expression which control plant development and response to environmental cues. We have analyzed microtranscriptomes of five barley developmental stages. Generally, during the barley development, miR168-3p and miR1432-5p levels increase while the 5'U-miR156-5p level decreases (with exception for the 2-week-o...

An experiment was conducted to evaluate the tolerance of micropropagated and mycorrhized alpinia plants to the parasite Meloidogyne arenaria. The experimental design was completely randomized with a factorial arrangement of four inoculation treatments with arbuscular mycorrhizal fungi (AMF) (Gigaspora albida, Claroideoglomus etunicatum, Acaulospora longula, and a non-inoculated control) in the ...

Legumes of the genera Astragalus (milkvetch), Coronilla (crownvetch), Lathyrus (pea vine), Lotus (birdsfoot trefoil), Medicago (alfalfa), Melilotus (clover), Trifolium (clover), and Vicia (common vetch) were inoculated with a population of Melaidogyne chitwoodi from Utah or with one of three M. hapla populations from California, Utah, and Wyoming.Thirty-nine percent to 86% of alfalfa (M. scutel...
