“…Two main groups of upregulated DEGs in the "Lipid degradation" sub-sub category were (1) lipase-like proteins (including patatins) and (2) esterase-like proteins with uncertain activity potentially related to lipids (GDSL esterase/lipase, esterase/lipase/thioesterase family proteins). Within the "Amino acid metabolism" subcategory, 8 of 20 upregulated DEGs were related to arginine metabolism, which has been previously shown to be enhanced during different plant-pathogen interactions [15,36,37].…”

“…Some physiological reactions following M. nivale infection have been demonstrated to be host plant genotype-dependent. Superoxide dismutase (SOD) activity was decreased in triticale during M. nivale infection [15]; herewith, changes in SOD activity varied in different host plant cultivars [16]. The level of lipid peroxidation in M. nivale-infected triticale cultivars has been shown to correspond to the level of host susceptibility: the more susceptible the cultivar, the more pronounced the lipid peroxidation [15].…”

Microdochium nivale is a progressive and devastating phytopathogen that causes different types of cereal crop and grass diseases that are poorly characterized at the molecular level. Although rye (Secale cereale L.) is one of the most resistant crops to most of the phytopathogens, it is severely damaged by M. nivale. The recent high-quality chromosome-scale assembly of rye genome has improved whole-genome studies of this crop. In the present work, the first transcriptome study of the M. nivale-infected crop plant (rye) with the detailed functional gene classification was carried out, along with the physiological verification of the RNA-Seq data. The results revealed plant reactions that contributed to their resistance or susceptibility to M. nivale. Phytohormone abscisic acid was shown to promote plant tolerance to M. nivale. Flavonoids were proposed to contribute to plant resistance to this pathogen. The upregulation of plant lipase encoding genes and the induction of lipase activity in M. nivale-infected plants revealed in our study were presumed to play an important role in plant susceptibility to the studied phytopathogen. Our work disclosed important aspects of plant-M. nivale interactions, outlined the directions for future studies on poorly characterized plant diseases caused by this phytopathogen, and provided new opportunities to improve cereals breeding and food security strategies.

“…On challenge with M. nivale , ‘Hewo’ showed a marked increase in chitinase while none of the cultivars showed a change in glucanase, confirming the role of chitinases in resistance against M. nivale [ 54 ]. Gawrońska and Gołębiowska [ 55 ] identified biochemical markers that are potentially involved in increased resistance against M. nivale . It was shown that the triticale genotype and seedling treatment may influence the level of TBARS, which is well-known as a marker of oxidative stress in response to different abiotic and biotic factors.…”

This review article presents the greatest challenges in modern triticale breeding. Genetic maps that were developed and described thus far, together with the quantitative trait loci and candidate genes linked to important traits are also described. The most important part of this review is dedicated to a winter triticale mapping population based on doubled haploid lines obtained from a cross of the cultivars ‘Hewo’ and ‘Magnat’. Many research studies on this population have focused on the analysis of quantitative trait loci regions associated with abiotic (drought and freezing) and biotic (pink snow mold and powdery mildew) stress tolerance as well as related to other important breeding traits such as stem length, plant height, spike length, number of the productive spikelets per spike, number of grains per spike, and thousand kernel weight. In addition, candidate genes located among these regions are described in detail. A comparison analysis of all of these results revealed the location of common quantitative trait loci regions on the rye chromosomes 4R, 5R, and 6R, with a particular emphasis on chromosome 5R. Described here are the candidate genes identified in the above genome regions that may potentially play an important role in the analysis of trait expression. Nevertheless, these results should guide further research using molecular methods of gene identification and it is worth extending the research to other mapping populations. The article is also a review of research led by other authors on the triticale tolerance to the most current stress factors appearing in the breeding.

“…After electrophoresis (4 • C, 180 V), SOD bands were visualized using the staining method described by Beauchamp and Fridovich [43]. The gels were incubated in a staining buffer (PB with 10 mM EDTA, 28 mM tetramethylethylenediamine (TEMED), 22 mM riboflavin and 0.25 mM nitro blue tetrazolium (NBT); pH 7.8 for 20 min in darkness, and then exposed to white light until SOD activity bands became visible [44].…”

Industrial and agronomic activities lead to oversupply and accumulation of elements in the environment. Relatively little is known about mechanisms of manganese (Mn) triggered stress. In this study, different cultivars of popular cereals wheat, oat, and barley were investigated for their response to excessive Mn. Manganese ions (MnCl2) at 5 and 10 mM were applied to the grains and then to the media on which the plants grew until they developed their first leaf. It was performed ICP MS aiming to understand the mechanism of manganese stress in susceptible and resistant cultivar. Under Mn-stress a decrease in fresh weight of plants was observed, also differences in water content in first leaves, an increase in superoxide dismutases (SOD) and peroxidases (POX) activity, and a significant rise in catalase (CAT) was only characteristic for barley. Increasing Mn concentration resulted in enhancing of manganese superoxide dismutase (Mn-SOD) and copper, zinc superoxide dismutase (Cu/Zn-SOD) bands intensity. The increase in proline content, depending on a balance between pyrroline-5-carboxylate synthase (P5CS), ornithine-d-aminotransferase (OAT), and proline dehydrogenases (PHD) activities, indicated osmotic disorders in all plants and differentiated the studied cereals. Microscopic observations of changes in the structure of plastids and starch accumulation in Mn presence were particularly visible in sensitive cultivars. The study ranked the tested cereals in terms of their tolerance to Mn from the most tolerant wheat through barley and the least tolerant oats.
