Response of 19 wheat varieties cultivated in Hungary varied within large limits to soil borne Rhizoctonia infection. The most frequent symptom, usually leading to damping off was the root neck necrosis. Four significant factors influencing the susceptibility of wheat comprised 71% of total variation but none of them was dominant. The inhibition of development of survivors in Rhizoctonia infested soil correlated with overall susceptibility of variety concerned. The varieties Emese, Kikelet and Palotás are proved to be less susceptible, but none of the varieties could be certified as tolerant. No relationships were revealed between pathogenicity of 26 Rhizoctonia strains studied and their taxonomic position or origin. The anamorph strains of Athelia, Ceratobasidium, Ceratorhiza and Waitea similar to Thanatephorus anamorphs selectively infected the wheat varieties, but the syndromatic pictures were undistinguishable with unarmed eye. R. solani was proved to be more aggressive against germinating wheat than R. cerealis. Nine significant factors influencing the virulence of Rhizoctonia strains comprised 82% of total variation, and six of them influenced exclusively Thanatephorus anamorphs.

Plant host defense peptides (HDPs), also known as antimicrobial peptides (AMPs), are regarded as one of the most prevalent barriers elaborated by plants to combat various infective agents. Among the multiple classes of HDPs, the Snakin class attracts special concern, as they carry 12 cysteine residues, being the foremost cysteine-rich peptides of the plant HDPs. Also, their cysteines are present at very highly conserved positions and arranged in an extremely similar way among different members. Like other plant HDPs, Snakins have been shown to exhibit strong antifungal and antibacterial activity against a wide range of plant pathogens. Moreover, they display diversified biological activities in many aspects of plant growth and the development process. This review is devoted to present the general characters of the Snakin class of plant HDPs, as well as the individual features of different Snakin family members. Specifically, the sequence properties, spatial structures, distributions, expression patterns and biological activities of Snakins are described. In addition, further detailed classification of the Snakin family members, along with their possible mode of action and potential applications in the field of agronomy and pathology are discussed.

Even before the perception or interaction with pathogens, plants rely on constitutively guardian molecules, often specific to tissue or stage, with further expression after contact with the pathogen. These guardians include small molecules as antimicrobial peptides (AMPs), generally cysteine-rich, functioning to prevent pathogen establishment. Some of these AMPs are shared among eukaryotes (eg, defensins and cyclotides), others are plant specific (eg, snakins), while some are specific to certain plant families (such as heveins). When compared with other organisms, plants tend to present a higher amount of AMP isoforms due to gene duplications or polyploidy, an occurrence possibly also associated with the sessile habit of plants, which prevents them from evading biotic and environmental stresses. Therefore, plants arise as a rich resource for new AMPs. As these molecules are difficult to retrieve from databases using simple sequence alignments, a description of their characteristics and in silico (bioinformatics) approaches used to retrieve them is provided, considering resources and databases available. The possibilities and applications based on tools versus database approaches are considerable and have been so far underestimated.
