“…Wheat and barley produce oxalate oxidase proteins, also known as germins [ 212 , 213 ], which break down oxalic acid, increasing their pathogen resistance [ 214 ]. Transgenic crops with wheat or barley oxalate oxidase genes showed increased resistance to S. sclerotiorum [ 215 , 216 , 217 ] and other pests [ 218 , 219 , 220 , 221 ].…”

Plants have developed a complex defense system against diverse pests and pathogens. Once pathogens overcome mechanical barriers to infection, plant receptors initiate signaling pathways driving the expression of defense response genes. Plant immune systems rely on their ability to recognize enemy molecules, carry out signal transduction, and respond defensively through pathways involving many genes and their products. Pathogens actively attempt to evade and interfere with response pathways, selecting for a decentralized, multicomponent immune system. Recent advances in molecular techniques have greatly expanded our understanding of plant immunity, largely driven by potential application to agricultural systems. Here, we review the major plant immune system components, state of the art knowledge, and future direction of research on plant–pathogen interactions. In our review, we will discuss how the decentralization of plant immune systems have provided both increased evolutionary opportunity for pathogen resistance, as well as additional mechanisms for pathogen inhibition of such defense responses. We conclude that the rapid advances in bioinformatics and molecular biology are driving an explosion of information that will advance agricultural production and illustrate how complex molecular interactions evolve.

“…Because of a potential major importance of GLP in protecting cells from superoxide toxicity produced under pathogen attacks, germin or GLP genes (i.e. HvOXO1) have been inserted into dicot plants like rapeseed or peanut to enhance its pathogen resistance (48)(49)(50). Given that several quinoa GLPs were expressed upon interaction with Trichoderma, it is very likely that these GLP defensins have an important role in the plant immune response of quinoa.…”

Symbiotic strains of fungi in the genus Trichoderma affect growth and pathogen resistance of many plant species, but the interaction is not known in molecular detail. Here we describe the transcriptomic response of two cultivars of the crop Chenopodium quinoa to axenic co-cultivation with Trichoderma harzianum BOL-12 and Trichoderma afroharzianum T22. The response of C. quinoa roots to BOL-12 and T22 in the early phases of interaction was studied by RNA sequencing and RT-qPCR verification. Interaction with the two fungal strains induced partially overlapping gene expression responses. Comparing the two plant genotypes, a broad spectrum of putative quinoa defense genes were found activated in the cultivar Kurmi but not in the Real cultivar. In cultivar Kurmi, relatively small effects were observed for classical pathogen response pathways but instead a C. quinoa-specific clade of germin-like genes were activated. Germin-like genes were found to be more rapidly induced in cultivar Kurmi as compared to Real. The same germin-like genes were found to also be upregulated systemically in the leaves. No strong correlation was observed between any of the known hormone-mediated defense response pathways and any of the quinoa-Trichoderma interactions. The differences in responses are relevant for the capabilities of applying Trichoderma agents for crop protection of different cultivars of C. quinoa.

“…The resistance of rapeseed to S. sclerotiorum obtained by using transgenic technology has mainly been based on observations of resistance in detached leaves in in vitro experiments ( Wang et al , 2014 ; Liu et al , 2015 ). In the present study, transgenic OsPGIP2 -overexpressing lines were created in two B. napus backgrounds and resulted in rapeseed plants with increased resistance to S. sclerotiorum , as indicated by survival tests after spraying with fungal hyphae and by the assessment of three consecutive years of stem inoculation with S. sclerotiorum in the field.…”
