“…The molecular mechanisms of resistance against bird cherry-oat aphids can be associated with the tryptophan-derived compounds, tryptamine, and serotonin, which accumulate in tissues of Setaria viridis (L.) P.Beauv. (green foxtail) plants [ 68 ].…”

The genetic resources of cereal crops in terms of resistance to aphids are reviewed. Phytosanitary destabilization led to a significant increase in the harmfulness of this group of insects. The breeding of resistant plant genotypes is a radical, the cheapest, and environmentally safe way of pest control. The genetic homogeneity of crops hastens the adaptive microevolution of harmful organisms. Both major and minor aphid resistance genes of cereal plants interact with insects differentially. Therefore, rational breeding envisages the expansion of the genetic diversity of cultivated varieties. The possibilities of replenishing the stock of effective resistance genes by studying the collection of cultivated cereals, introgression, and creating mutant forms are considered. The interaction of insects with plants is subject to the gene-for-gene relationship. Plant resistance genes are characterized by close linkage and multiple allelism. The realizing plant genotype depends on the phytophage biotype. Information about the mechanisms of constitutional and induced plant resistance is discussed. Resistance genes differ in terms of stability of expression. The duration of the period when varieties remain resistant is not related either to its phenotypic manifestation or to the number of resistance genes. One explanation for the phenomenon of durable resistance is the association of the virulence mutation with pest viability.

“…Comprehensive information on conserved plant gene function would be valuable not only for basic science to promote understanding of photosynthetic biology, but could also help in understanding the contributions of unknown genes to important agronomic traits. For example, four Setaria loci (Sevir.1G224300, Sevir.5G282600, Sevir.5G335650, Sevir.9G583700) identified as being linked to responses to extremes in precipitation and temperature (Mamidi et al, 2020), and 107 genes up- or down-regulated in response to aphid infection (Dangol et al, 2022) were part of our Setaria Deep Green protein set and are excellent candidates for further characterization.…”

An explosion of sequenced genomes and predicted proteomes enabled by low cost deep sequencing has revolutionized biology. Unfortunately, protein functional annotation is more complex, and has not kept pace with the sequencing revolution. We identified unannotated proteins in three model organisms representing distinct parts of the green lineage (Viridiplantae); Arabidopsis thaliana (dicot), Setaria viridis (monocot), and Chlamydomonas reinhardtii (Chlorophyte alga). Using similarity searching we found the subset of unannotated proteins that were conserved between these species and defined them as Deep Green proteins. Informatic, genomic, and structural predictions were leveraged to begin inferring functional information about Deep Green genes and proteins. The Deep Green set was enriched for proteins with predicted chloroplast targeting signals that are predictive of photosynthetic or plastid functions. Strikingly, structural predictions using AlphaFold and comparisons to known structures show that a significant proportion of Deep Green proteins may possess novel protein tertiary structures. The Deep Green genes and proteins provide a starting resource of high value targets for further investigation of potentially new protein structures and functions that are conserved in the green lineage.

“…Likewise, several studies have unveiled the evident role of serotonin in mediating plant defense against herbivory. In Setaria viridis, for instance, exogenous application of serotonin to the plant medium reduced the survival of Rhophalosiphum padi aphid adults, as well as the body weight of the surviving aphid adults [22]. It has also been reported that serotonin content clearly increased following the feeding of rice striped stem borer Chilo suppressalis in rice leaves [23].…”

Serotonin is a well-known secondary metabolite that plays an important role in many growth and developmental processes, as well as biotic and abiotic stress responses of plants. Yet, whether serotonin biosynthesis regulates the resistance of rice to the brown planthopper (BPH) Nilaparvata lugens and its underling mechanisms have not been entirely investigated. In this study, we found that expression levels of four serotonin biosynthesis gene, OsTDC1, OsTDC2, OsTDC3, and OsT5H, and the serotonin content were significantly induced by BPH nymph infestation. The rice seedlings pretreated with serotonin were more attractive to BPH nymphs and promoted their feeding behavior as indicated by increased honeydew excretion. In addition, serotonin application to artificial diets increased the survival rates of BPH nymphs in a dose-dependent manner compared to the controls. Moreover, the exogenous serotonin application to rice seedlings increased the average injury scale and functional plant loss indices caused by BPH nymph infestation. Moreover, supplemented serotonin enhanced soluble sugar and free amino acid contents, as well as the activities of SOD, POD, and PPO, but repressed the production of flavonoids. Our findings illustrated that serotonin plays a negative role in the regulation of rice resistance to BPH nymphs probably by modulating contents of soluble sugars, free amino acids, and flavonoids.
