“…It is worth noting that RR did not appear as abnormal mitochondria until 8-15 dpi (Figure 4), suggesting that RR has a stronger capacity in resisting rust pathogen infection than RS. Studies on fungal diseases demonstrated that increasing respiration was a basic response to injury in most infected host tissues [27]. The increase and aggregation of mitochondria were observed in RR and RS at a later stage of infection, which might be due to the enhanced respiration at the infected site caused by pathogen infection.…”

“…Previous studies have shown that even minor damage to photosynthesis can weaken the defense systems and increase the susceptibility of the plants to pests and pathogens [27]. The chloroplast disorder led to the change or rearrangement of the chloroplast ultrastructure, which could be related to the development of plant symptoms after pathogen infection [29].…”

Zoysiagrass (Zoysia japonica) is a popular turfgrass species and is widely used for sport turf and urban landscape. Zoysiagrass is often infected by Puccinia zoysiae, which causes a loss in turf quality. The physiological and molecular mechanisms of rust resistance are poorly understood in this species. In this study, the rust-resistant and susceptible lines of zoysiagrass were inoculated with P. zoysiae, and alterations of leaf cell structure, physiological indicators and transcriptomic response were investigated at the various stages of inoculation. After inoculation, the cell membranes, nucleus, mitochondria, and chloroplast were all impaired, followed by abnormal physiological metabolism. The damage occurred earlier and more severely in the susceptible line. Changes in electrolyte leakage and chlorophyll content varied with the genotype and the inoculation stages. The transcriptome analysis showed that plant hormones, MAPK signal transduction pathway, photosynthesis and energy generation pathways were significantly enriched in the early response, in both the resistant and susceptible lines. The results provided insights into the physiological and molecular mechanisms of rust disease resistance and would benefit the breeding of rust-resistant varieties in zoysiagrass and related turfgrass species.

Winter wheat is the most valuable agricultural crop, which occupies one of the first places in the balance of grain crops of the Central region of the Non-Chernozem zone of Russia. Year after year, there is an increasing need to expand the production of grain products, which can be provided by varieties that give high and stable yields over the years. Creation of environmentally plastic varieties is a promising and popular direction of breeding work in recent years. The evaluation of samples in the breeding process for ecological plasticity and yield stability allows to identify varieties most adapted to growing conditions, as well as having high potential productivity. To identify the most valuable samples for the complex of economically useful traits a breeding evaluation of soft winter wheat promising lines obtained using source material of various ecological and geographical origin was carried out in the FSEI HE RSAU-MAA named after K.A. Timiryazev. As a result of the study, the most valuable sample 50h (Azotfixifuyushchaya x Moscovskaya 40) was selected in a competitive variety testing, which significantly exceeded the yield standard, and was also characterized by high grain quality and resistance to powdery mildew. This promising sample, which has high indicators for a complex of economically valuable traits, is planned to be transferred to the State variety testing. Variety samples were identified that showed high resistance to snow mold 32h (Sharada × Nemchinovskaya 24) and 52h (Nemchinovskaya 24× Zimorodok), which we recommend to use in further breeding for resistance to this disease.
