Taheri H, Bazgir E (2022) The role of autophagy in plants protection against pathogens. Plant Pathology Science 11(1):133-145. Doi: 10.2982/PPS.11.1.133.
Autophagy plays an important role in the process of plant development and interaction with pathogens such as fungi, bacteria, and plant viruses. Autophagy is linked to immunity and disease resistance through inhibition of programmed cell death (PCD) and is recognized as an important defense component in plants. Autophagy also helps selectively eliminate pathogens through specific interactions. A number of pathogens have acquired the ability to cope with or evade autophagy and use it to develop the disease. Some other pathogens also use the autophagy system as pathogenic factors. Therefore, understanding cellular processes such as responses related to autophagy genes are very important for studying pathological physiology and plant immunity. The role of autophagy in the immune system and the plant's defense response to pathogens is described in this article.

Abstract
Cereal cyst nematode is acknowledged globally as a biotic constraint for wheat production in the world. A total of 150 composite soil and root samples were randomly taken from wheat fields of Kohgiluyeh and Boyer-Ahmad province during 2016-2020, along with recording the geographical coordinates of the sampled locations. Species was identified based on morphological and morphometric features and molecular characters. Among 75 soil samples, from rain-fed and irrigated wheat fields of the province, 42 soil samples (56%) contained Heteroderafilipjevi. The percentage of infested of rain-fed and irrigated wheat fields in the province was estimated to be 55 and 57.6 respectively, with 2.6 eggs and J2s/g of soil. The average population of eggs and second-stage juveniles (J2s) in cysts extracted from infested soils collected from wheat fields in the province was estimated as. The minimum population density of H. filipjevi (0.5 eggs and J2s/g of soil) was found in wheat fields of villages Tol Khosrow in Boyer-Ahmad county. The rain-fed wheat field (Dehdasht cultivar) of Lirab village in Basht county with 13.7 eggs and J2s/g of soil, has the highest mean population density of H. filipjevi. The average population of eggs and J2s in both rain-fed and irrigated wheat fields infested with the H. filipjevi in all counties of the province were estimated to be 2.6 and 2.51/g soil, respectively. In total rain-fed and irrigated wheat fields, the highest and lowest mean populations of eggs and J2s of H. filipjevi were 4.9 and 1.18, respectively, in Basht and Gachsaran counties.
