“…They break down peptides host cell are broken down by proteolytic bacteria and subsequently used either in growth. Protein inhibitors such as trypsin inhibitor are one way to counteract the host against plant pathogens (Moulin et al 2014). Anthocyanins are plant pigments that are also involved in microbial resistance.…”

The aim of this study is to evaluate the storage and qualitative feature of modi ed Red Rey Iranian Onion. Firstly, the modi ed population was obtained by the selection of superior bulbs, cultivation, its self-pollination and consequently the identi cation of the best families and implement open pollination between them. In next level, the Red Rey Iranian modi ed with basic population and Red Azar-shahr cultivar (comparative) was crossed. Our results showed that the selection procedure has leading to improvement in variety of traits in population. Also, the modi ed Red Rey is signi cantly superior to the base mass in qualitative traits such as: bulb stiffness, bulb dry matter, TSS, total sugar and glucose; So that the percentage of dry bulb content increased from 10.4% in the basal mass to 11.1% in the modi ed Red Rey; while spouring and rotting, minerals, and dry matter, vitamin C and fructose-reducing sugar was not affected by genotype. In the second step, resistances to Fusarium wilt disease (laboratory and molecular markers) were evaluated. Based on the results of phenotypic evaluation, the modi ed Red Rey had the lowest rate and level of infection and the highest score. According to the results of genotypic evaluation, there is a very high genetic a nity between resistant and susceptible cultivars.

This review describes plant originated serine protease inhibitors (SPIs) that target or inhibit different families of serine proteases (SPs), protein-digesting enzymes of various pathogens. SPs play a crucial task in many biological events by catalyzing proteolysis that serves as mediators of signal initiation, transmission and termination of the cellular events leading to regulation of an organism's life cycle. The activity of proteases has to be closely regulated by proteinase inhibitors (PIs) to avoid the damage that proteases might cause in vivo, in the host organism. Based on the selectivity and inhibitory activity PIs are categorized into four mechanistic class viz. aspartic PI (pepstatins), serine PI (serpins), cysteine PI (cystatins) and metallocarboxy PI. Among these SPI family is the largest. Many organisms including bacteria, fungus, viruses, protists, insects and vertebrates derive their nutritional requirement from various life forms by finding a suitable host. Proteases constitute 1-5% of genomes of these infectious organisms among which SPs regulate protein synthesis, turnover and physiological functions viz. fertilization, growth and development, digestion, cell signaling or migration, immune defense, wound healing and disease propagation. SPs mediate the process of pathogenesis and/or host tissue penetration for a number of diseases in the host organisms. SPs are generally found either as constitutive components in plant storage tissues like seeds and tubers or expressed in response to pest and pathogen attack besides acting as a defense system against a wide variety of pathogens. These expressed or endogenously present SPIs can attenuate SPs with cross-protection against a wide array of protease families of pathogens like bacteria, fungus, nematodes and viruses.
