Kinds, Purification and Morphological Characteristics of Plant Viruses

Enzyme - assisted Purification of two Phloem - limited Plant Viruses

Tobacco necrotic dwarf (TNDV) and potato leafroll (PLRV), viruses which are normally phloem-limited and are transmitted by aphids in the persistent manner, were successfully purified using Driselase, an enzyme that macerates plant tissue. Frozen tissue of Physalisfloridana infected with TNDV or PLRV was homogenized in buffer containing Driselase and incubated with shaking. The virus particles w...

Morphological and biochemical characteristics of dreb2a mutant plant grown under normal conditions

DREB transcription factors are one of the largest families of transcription factors in plants that are believed to play important regulatory functions in tolerance to environmental stress, but there is no complete information on their role in controlling the morphological and antioxidant properties of developed plants under normal conditions. In this study, some phenotypic characteristics of th...

Effect of Plant Density and Weed Interference on Morphological Characteristics and Yield of Corn (Zea Mays L.)

Objective: Field experiment was conducted in 2009 to investigate the effects of plant density and weed interference on morphological characteristics and yield of corn (Zea Mays, L.) at Research Station of University of Tabriz, Tabriz, Iran. Methods: The experiment was arranged as split plot based on randomized complete block design with three replications. Plant density (D1, D2, D3 and D4: 5, 7...
