Identification of Genes in a Partially Resistant Genotype of Avena sativa Expressed in Response to Puccinia coronata Infection
Cultivated oat (Avena sativa), an important crop in many countries, can suffer significant losses through infection by the fungus Puccinia coronata, the causal agent of crown rust disease. Understanding the molecular basis of existing partial resistance to this disease might provide targets of interest for crop improvement programs. A suppressive subtractive hybridization (SSH) library was cons...
متن کاملOn the taxonomy of Puccinia coronata in Iran
In the present study, infra specific taxonomy of Puccinia coronata in Iran was studied. Based on morphological characters only, four P. coronata varieties were recognized in Iran. These are: P. coronata var. coronata, P. c. var. avenae, P. c. var. hordei and P. c. var. golestanica var. nov. Descriptions of the four varieties and their host range are provided. Several new hosts for aecial and te...
متن کاملThe Plasma Membrane of Avena Coleoptile
Treatment of living protoplasts from the Avenia coleoptile with enzymes and chemicals has provided new information about the external surface of the plasma membrane. Treatments with selected detergents and polyene antibiotics indicate that little sterol is present. The lysis of protoplasts in carboxymethyl-RNase which is enzymatically almost inactive provides strong evidence that the lysis prev...
متن کاملInhibition of cell elongation in Avena coleoptile by hydroxyproline.
A study has been made of the hydroxyproline-induced inhibition of elongation of Avena coleoptile tissues. The isomers of 4-hydroxyproline differ in their effectiveness; only the L isomers are growth inhibitors with the cis form (allohydroxyproline) being more effective than the trans form (hydroxyproline). Hydroxyproline differs from other amino acid antagonists and protein synthesis inhibitors...
متن کاملSecond positive phototropism in the Avena coleoptile.
A method has been developed whereby the second positive phototropism can be observed separately from the first positive and negative phototropic responses which also occur in oat coleoptiles. Although the second positive phototropic response has often been referred to as the base response, photoreception for it is shown to occur mainly in the apical 3 mm of the coleoptile. The Bunsen-Roscoe rec...
