Abstract

Sadravi  M. & Rahimizadeh  M. 2016. Ten  useful  Penicillium species. Plant Pathology Science 5(1):1-13.

Penicillium species have saprophytic live on plants debris, in the soil and also on some plant products, fresh and juicy damaged fruits as well as the storage fruit and grains.  They can characterized by studying the features of their colony, conidiophores, phialids  and conidia on selective culture media. The ability of some isolates of P. aurantiogriseum, P. bilaiae, P. chrysogenum, P. citrinum, P. funiculosus, P. glabrum, P. griseofulvum, P. oxalicum, P. purpurogenum and P. simplicissimum to control plants diseases such as Fusarium and Verticillium wilt of tomato, pulse white and gray molds, brown rot and blight twig of peach, late blight and cyst of potato has been proved. They also can act as plant growth promoter. Key  morphological characteristics of  these ten species of Penicillium  is described in this paper. Most of these species are reported from Iran, thus identification and use of the efficient isolates of them can be suggested in management of plants diseases or in enhancement of plants growth programs.

Tahmasebi A, GhodoumParizipour MH (2020) The role of brassinosteroid hormones in plant response to pathogens. Plant Pathology Science 9(1):108-117.          DOI: 10.2982/PPS.9.1.108.
Plants are usually attacked by several pathogens. Different defense pathways in plants have evolved in reaction to pathogens. Plant defense responses have been shown to be regulated by various plant hormones. Brassinosteroids are plant-specific steroid hormones that play important roles in regulating growth and developmental processes. In addition to acting as a regulator of plant growth, they also play a role in defense responses to pathogens. Many researches have been done on their role in plant resistance to fungi, bacteria and viruses, which are described in this article. Further understanding of the role of these hormones in plant defense responses can be useful in inducing resistance or producing plants resistant to pathogens.

Sadeghi Garmaroodi H, Seyed Masoumi SY, Nankali A (2022) The reaction of thirteen peach and nectarine cultivars to Verticillium wilt. Plant Pathology Science 11(1):60-73.                  Doi: 10.2982/PPS.11.1.60.
 
Introduction: Verticillium wilt, caused by Verticillium dahliae, is one of the most important soil-borne diseases of stone-fruit trees. Materials and Methods: Samples showing evidence of Verticillium wilt were collected from stone fruit orchards in the suburbs of Shahroud and Damavand and four isolates of V. dahliae were obtained. The fungal inoculum was prepared on sterile wheat grains and the response of 13 peach and nectarine cultivars propagated by grafting on GF305 (almond-peach hybrid) rootstock was inoculated with it in the canopy area in the garden in early spring. Sixteen weeks after inoculation, disease severity was recorded on a three-point scale. Results: All peach and nectarine cultivars were classified as very susceptible, susceptible, or semi-susceptible and none of them showed resistance. The Nectarine Independence cultivar was highly susceptible to disease, while the peach cultivar had the lowest disease severity index and was therefore classified as semi-susceptible. Conclusion: Among these cultivars, the Romestar peach cultivar is less susceptible to the disease.
