“…The result is a reduction in the photosynthetic surface of the plant, which eventually causes leaf mortality and a decline in leaf quality [ 52 , 53 ]. Small oval- to diamond-shaped spots that appear periodically on wheat and triticale leaves are the symptoms of the leaves [ 54 ]. This disease may destroy plant vegetative parts like leaves, causing the infected plants to die before heading [ 55 ].…”

“…In all of the main wheat-growing countries of Syria, Brazil, Argentina, Australia, Algeria, the United States, Russia, Canada, and a few other nations, the brown-black leaf spot is a common occurrence [ 57 , 60 , 61 ]. ToxA, ToxB, and ToxC are the three known effectors produced by tan spots of wheat [ 54 , 62 , 63 , 64 ]. While ToxC is yet unidentified and considered to be a metabolite, ToxA and ToxB are proteins [ 54 , 64 ].…”

Cereal production plays a major role in both animal and human diets throughout the world. However, cereal crops are vulnerable to attacks by fungal pathogens on the foliage, disrupting their biological cycle and photosynthesis, which can reduce yields by 15–20% or even 60%. Consumers are concerned about the excessive use of synthetic pesticides given their harmful effects on human health and the environment. As a result, the search for alternative solutions to protect crops has attracted the interest of scientists around the world. Among these solutions, biological control using beneficial microorganisms has taken on considerable importance, and several biological control agents (BCAs) have been studied, including species belonging to the genera Bacillus, Pseudomonas, Streptomyces, Trichoderma, Cladosporium, and Epicoccum, most of which include plants of growth-promoting rhizobacteria (PGPRs). Bacillus has proved to be a broad-spectrum agent against these leaf cereal diseases. Interaction between plant and beneficial agents occurs as direct mycoparasitism or hyperparasitism by a mixed pathway via the secretion of lytic enzymes, growth enzymes, and antibiotics, or by an indirect interaction involving competition for nutrients or space and the induction of host resistance (systemic acquired resistance (SAR) or induced systemic resistance (ISR) pathway). We mainly demonstrate the role of BCAs in the defense against fungal diseases of cereal leaves. To enhance a solution-based crop protection approach, it is also important to understand the mechanism of action of BCAs/molecules/plants. Research in the field of preventing cereal diseases is still ongoing.

The results of the study of architectonics and physical and mechanical properties of the stems of selective forms of spring hexaploid triticale of different ecological and geographical origin are presented. Traits of 19 collection and breeding samples from the collections of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) and the Siberian Research Institute of Plant Growing and Selection - branch of the Federal Research Center of the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences (SibNIIRS – branch of the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences) served as research objects. Macrometric parameters were studied on 25 representative specimens of each breeding sample when they reached the phase of full ripeness during three years (2021–2023). The resistance of the stem to bending or fracture was determined on an experimental specimen manufactured at the SibNIIRS with a stable platform, bars for fixing the specimen and a slot for placing a dynamometer. The susceptibility of triticale plants to lodging was evaluated by a set of traits: weight of a 10-cm straw of the 2nd internode; stem resistance to breaking determined by the peak reading of an electronic dynamometer; stem tissue density of the 2nd internode. The studied samples differed significantly in these parameters and were characterized by different degrees of the resistance to lodging. Promising breeding specimens that can be used as sources of valuable traits have been identified based on the totality of the strength parameters. Application of the principal component method allowed to identify the marker trait "sum of lengths of the 2nd and 3rd internodes", which was determinant in providing high lodging resistance in the studied samples. A close relationship between the trait of 10-cm straw mass of the 2nd internode and the parameter of the stem resistance to breakage has been established. The conjugation of these characteristics will make it possible to identify the sources of valuable traits and purposefully carry out the selection process of triticale for resistance to lodging without attracting short-stemmed forms.
