Opis:: Barley phylloplane is seriously colonized by Drechslera graminea, the causal agent of leaf stripe disease in the hos. The present study involved the elucidation of alterations induced in the protein content of the host due to Drechslera infection. Naturally growing barley plants were obtained from fields and Drechslera graminea was isolated and identified from diseased plants’ leaves. After identification and preparation of the pure culture, the pathogen was inoculated on plants grown under aseptic and controlled laboratory conditions. Changes in the total soluble cytoplasmic proteins and defense enzymes of the host such as polyphenol oxidase (PPO), peroxidase (POX), phenylalanine lyase (PAL) and tyrosine ammonia lyase (TAL) were observed up to 5 h after inoculation. The results demonstrated a significant effect of the pathogen on the cytoplasmic protein expression of the host as well as in its defense system.

Opis:: Leaf scald, caused by the necrotrophic fungus Monographella albescens, is one of the main threats to rice (Oryza sativa L.) around the world. This disease decreases yields in rice by up to 30% because of dead leaf tissue, damaged seeds, and sterile flowers. Currently, there is limited knowledge about the molecular mechanisms involved in rice plant resistance against this pathogen. For this purpose, six commercial cultivars of rice were primarily screened for M. albescens infection and development. Dasht and Salari were found to be the most resistant and susceptible to M. albescens infection, respectively. The plants were kept in a greenhouse at 29 ± 2°C during the day and 26 ± 2°C at night with a relative air humidity of 85 ± 5%. Forty-five days after sowing, the plants with three biological replications were inoculated by transferring a PDA disc (0.3 cm2) containing M. albescens mycelia to the middle third of the 7th, 8th, and 9th completely open leaves. The leaves were collected 24, 48, 72, 96 and 120 hai. Leaf samples were also collected from the non-inoculated plants (0 h) to serve as controls. Real-time quantitative PCR (RT-qPCR) showed rapid induction and significant accumulation of jasmonic acid (JA) and ethylene (ET) responsive genes such as lipoxygenase (LOX), allene oxide synthase 2 (Aos2), jasmonic acid carboxyl methyltransferase 1 (JMT1) and ACC synthase 1 (ACS1) in the resistant Dasht cultivar after infection with M. albescens. Furthermore, the transcripts of salicylic acid (SA) responsive phenyl alanine ammonia lyase 1 (PAL1) and nonexpressor of pathogenesis-related genes 1 (NPR1) genes were induced in the incompatible interaction. The activities of the defense enzymes superoxide dismutase (SOD), peroxidase (POX) and glutathione reductase (GR) increased strongly in Dasht in response to M. albescens infection. In addition, there was an increase in the H2 O2 levels in the leaves of the Dasht cultivar during the infectious period of M. albescens associated with the enhancement of catalase (CAT) activity as well as higher levels of malondialdehyde (MDA). This is the first study on the interaction between rice and M. albescens at the molecular level. It can contribute to understanding how rice responds to pathogen infection, as well as assist with future research plans of molecular breeding regarding the tolerance to leaf scald disease.

Opis:: Lupine diseases caused by pathogenic fungi constitute a serious problem in agriculture. They lead to partial yield loss and deterioration of crop quality through the changes in biochemical composition of seeds or their contamination with mycotoxins. Some of common lupine diseases are fusarioses caused by Fusarium oxyspomm f. sp. lupini. Morphometric and metabolic changes were investigated in yellow lupine seedlings infected with F. oxyspomm f. sp. lupini. It was found that infection caused temporary inhibition of seedling growth, overcome at later development, and activation of ß-glycosidase and peroxidases. The changes in enzymes activity indicate the induction of defense mechanism against F. oxyspomm f. sp. lupini and inhibition of pathogen spread.
Choroby łubinu powodowane przez grzyby chorobotwórcze stanowią poważny problem w rolnictwie. Prowadzą do zniszczenia części plonu oraz pogorszenia jego jakości, poprzez zmiany w składzie biochemicznym nasion lub zakażenie ich mykotoksynami. Do powszechnie występujących chorób łubinu zaliczane są fuzariozy powodowane przez Fusarium oxysporum f. sp. lupini. Badano zmiany morfologiczne oraz metaboliczne w siewkach łubinu żółtego infekowanych F. oxysporum f. sp. lupini. Stwierdzono, że infekcja spowodowała okresowe zahamowanie wzrostu siewek, przełamane w dalszej fazie ich rozwoju oraz aktywację ß-glikozydazy oraz peroksydaz. Poinfekcyjne zmiany aktywności enzymów wskazują na uruchamianie mechanizmu obronnego względem F. oxysporum f. sp. lupini i zahamowanie rozprzestrzeniania się patogena.
