“…Recent studies have shown that kaempferol and apigenin treated pea plants exhibited a decrease in the intensity of aphid-sap ingestion, although treatment with these flavonoids did not prohibit aphid attack. Also kaempferol made the finding of sap-transporting vessels more difficult for aphids, underlining a protection role to biotic stress (Stec et al, 2021). Interestingly kaempferol together with quercetin glycosides such as rutin are found in the aerial parts of lentil plants, where the later compounds represent about 73% of the total determined flavonoids.…”

“…Flavonoids are regarded as secondary antioxidants that complement the primary antioxidants upon large alterations in redox homeostasis that depress the activity of the later while promoting the biosynthesis of the flavonoid antioxidants (Agati et al, 2020). Noteworthy that such flavonoids were previously shown to be linked to resistant genotypes (Togola et al, 2020;Stec et al, 2021) indicating an innate biotic stress response to aphid infestation. However what molecular mechanisms and chemical signals elicit this response remains to be explored.…”

Lentil cultivation is often hampered by aphid population outspreads with detrimental impacts to crop development and production, challenging food safety and agriculture sustainability. The pea aphid (Acyrthosiphon pisum) is a significant threat to lentil in the temperate zone rainfed systems. A set of management practices including resilient cultivars and application of insecticides have effectively controlled aphid infestation. However, the plant defense against insect pests is scantily dissected and limited to the individual components including antibiosis, antixenosis and tolerance that constitute a combination of plant stress responses. Utilizing a lentil germplasm collection, we assessed the antixenosis and aphid tolerance mechanisms in association to important morphological parameters. Physiological parameters including relative water content (RWC) measured at 24h and 48h post-aphid infestation revealed genotype-specific responses. The contents of key plant hormones including salicylic acid (SA), jasmonic acid (JA), abscisic acid (ABA) and indoleacetic acid (IAA) implicated in defense signal-transduction pathways were also determined in lentil accessions after aphid herbivory infestation. In parallel, the expression of hallmark defense genes governed by SA- and JA-signaling pathways at 24h and 48h post aphid herbivory revealed significant differentiation patterns among the accessions. An interplay of hormone crosstalk is unveiled that possibly governs defense responses and aphid resistance. Besides the metabolomic profiling of accessions under aphid herbivory indicated the indispensable role of key secondary metabolites accumulation such as flavonoids, alkaloids, phenolics and fatty acids as a front line of plant defense and a potential integration of hormone signaling pathways in metabolome reprogramming. Overall, the study presents a panorama of distinct lentil responses to aphids and a critical view of the molecular mechanisms implicated in lentil insect defense to further our insight and advance crop protection and breeding approaches in a climate changing environment.

“…Non-mycorrhizal C. aurantium plants were sprayed with six different compounds (kaempferol, luteolin, diconyferil alcohol, neohesperidin, malic acid, cinnamic acid) at a concentration of 0.5 mM in the range of other treatments with flavonoids (Wachter et al, 1999;Stec et al, 2021). Treatments were grouped according to the solvent used as a control.…”

Mycorrhizal Symbiosis Triggers Local Resistance in Citrus Plants Against Spider Mites

et al. 2022

Citrus plants are a highly mycotrophic species with high levels of fungal colonization. Citrus aurantium rootstocks typically show abundant root colonization by Rhizophagus irregularis three weeks after inoculation. Mycorrhizal symbiosis protects plants against multiple biotic stressors, however, such protection against spider mites remains controversial. We examined mycorrhiza-induced resistance (MIR) in citrus against the two-spotted spider mite Tetranychus urticae. Mycorrhized C. aurantium displayed reduced levels of damage in leaves and lower mite oviposition rates, compared to non-mycorrhized controls. Mycorrhization did not affect host choice of mites in Y-tube assays; of note, C. aurantium has innate strong antixenotic resistance against this mite. Analysis of metabolism pathways in mycorrhized citrus plants showed upregulated expression of the oxylipin-related genes LOX-2 and PR-3 early after infestation. Accordingly, jasmonic acid (JA), 12-oxo phytodienoic acid (OPDA), and JA-Ile concentrations were increased by mycorrhization. Non-targeted metabolomic analysis revealed the amino acid, oxocarboxylic acid, and phenylpropanoid metabolism as the three major pathways with more hits at 24 h post infection (hpi) in mycorrhized plants. Interestingly, there was a transition to a priming profile of these pathways at 48 hpi following infestation. Three flavonoids (i.e., malic acid, coumaric acid, and diconiferyl alcohol) were among the priming compounds. A mixture containing all these compounds provided efficient protection against the mite. Unexpectedly, systemic resistance did not improve after 72 h of primary infestation, probably due to the innate strong systemic resistance of C. aurantium. This is the first study to show that MIR is functional against T. urticae in locally infested citrus leaves, which is mediated by a complex pool of secondary metabolites and is likely coordinated by priming of JA-dependent responses.

“…Kasmiyati et al (2020) reported induced polyploidy using colchicine be able to increase flavonoid content. Furthermore, flavonoid affect the behavior of aphid especially it could decrease sap ingestion activity (Goławska et al, 2014;Stec et al, 2021). Considering that aphid is a kind of pest which is very often attacking beans and very difficult to manage, this result is an important progress in developing an aphid-resistant crop.…”

Induced mutagenesis is one way to improve the quality of crops, especially to increase the resistance to pests and diseases. This research aimed to determine colchicine and ethyl methane sulfonate (EMS) mutagenesis on cowpea M3 purple and mung bean Vima1, in concatenation for developing resistant crops. This research consists of four packages: (1) first package (cowpea M3 purple seeds treated with colchicine solution, (2) second package (cowpea M3 purple seeds treated with EMS solution), (3) third package (mung bean Vima1 seeds treated with colchicine solution) and (4) fourth package (mung bean Vima1 seeds treated with EMS solution). The results of this research revealed that induced mutagenesis by colchicine solution treatment reduced the incidence of bean leaf beetles up to 19% on cowpea M3 purple, as well leaf miners by 5% to 9% and bean leaf beetles up to 5% on mung bean Vima1. Treatment of EMS solution decreased the incidence of bean leaf beetles by 17% on cowpea M3 purple and pink mealybug by 5% to 15% on mung bean Vima1. Induced mutagenesis using EMS solution significantly decreased vegetable leaf miner incidence by 33% to 93% or 71% on average. Colchicine and EMS solution treatment caused aphid attacks in cowpea M3 purple, particularly in pods. The attacks did not happen on leaves and aphid incidence in pods was slower than in control. Some promising mutant candidates were found from this research that will be used in further crop development studies. It is expected that the method and results of this research could inspire faster development of resistant crops.
