Sadeghi  L. & Jamali  S. 2016. Molecular plants defense mechanisms against nematodes. Plant Pathology Science 5(2):90-100.

Plant  parasitic  nematodes can devastate a wide range of  crop  plants. They are obligate parasites and have evolved compatible parasitic relationship with their host plants to obtain nutrients that are necessary to support their development and reproduction. Suppression of host defense is a key step for pathogenesis in the compatible interaction. Plant defense response is activated from the moment a nematode penetrates the plant root. Stylet and secretions of esophageal glands play central roles at during invasion to host, migration inside the roots and establishment of feeding site on host cells. New findings demonstrate that secretions of esophageal  glands of  some  nematodes as  effectors deliver  into the apoplast and cytoplasm of host cells to active plant defense responses in resistant host. Molecular  plants defense mechanisms against nematodes described in this paper.

Abstract

Jamali S (2021) Truffles of Iran. Plant Pathology Science 10(2):1-14. Doi: 10.2982/PPS.10.2.1.
Truffles are edible fungi belonging to the phylum Ascomycota. These valuable fungi can be divided into two categories: desert and forest truffles. They are obligatory mycorrhiza forming with some trees, shrubs, annual and perennial plants. These fungi belong to 38 genera of six families of the order Pezizales, class Pezizomycetes. The forest truffles are classified in the Tuberaceae family and the desert truffles in the other families. The existence of Tuber aestivum from the family Tuberaceae, Terfezia claveryi, Terfezia boudieri, Tirmania pinoyi, and Tirmania nivea from the family Pezizaceae, Picoa juniperi, Picoa lefebvrei, Geopora cooperi and Geopora cooperi, from the family Pyronemataceae, has been morphologically and molecularly proven by researches in Iran. The morphological characteristics, symbiotic plants, and distribution areas of these fungi are described here.

Kazemian F, Jamali S, Alipour Z, Nasaj Hosseini SM (2023) The effect of four herbal compounds on root-knot nematode of kiwi. Plant Pathology Science 12(2):27-40. 

Introduction: Root-knot nematodes damage is one of the major problems in kiwifruit production in northern Iran. This research was carried out to investigate the possibility of using dried leaves of four plants to manage kiwifruit root-knot nematode. Materials and Methods: The soil and roots of diseased kiwifruit from the gardens of Rudsar City, Gilan Province, Iran were sampled and their root knot nematode was purified using the single egg mass method on the early Urbana tomato variety. The morphological characteristics of nematode second stage larvae and females were examined and nematode species were identified. By using the single egg mass technique, the necessary nematode population was reared on the early Urbana tomato. The effect of dry leaves of chrysanthemum, parsley, guava and oleander in two rates of 50 and 75 grams per kilogram of soil was evaluated in greenhouse conditions. The experiment was conducted in a completely randomized design with four replicates for each treatment on nematode-inoculated kiwi seedlings of Hayward cultivar. Nematode-related indices (number of galls, egg mass, eggs and J2s in 250 g of soil and reproductive factor) and plant growth characteristics (seedling height; root length and volume; fresh and dry weight of roots and shoots) were measured. Results: The root- knot nematode causing the disease in this region was identified as Meloidogyne incognita. In addition to controlling the nematode, the treatments used improved the growth of the kiwi seedlings. The results of the mean comparison of data showed that the treatment of 75 g of chrysanthemum leaves had a greater effect on reducing nematode population indices than other treatments. The next effective treatments were chrysanthemum at the rate of 50g, parsley at the rate of 75g, parsley at the rate of 50g, oleander at the rate of 75g, oleander at the rate of 50g, guava at the rate of 75g and guava at the rate of 50g, respectively. Treatment with 75 g of chrysanthemums also had the greatest effect on improving the growth rate of tomato seedlings. Conclusion: Adding 75g of dry chrysanthemum leaves to each kilogram of soil will help reduce root nematode damage and improve the growth of kiwi seedlings.
