This study identifies catechol acetylglucose as a benzoxazinoid-regulated defensive metabolite in maize and shows its role in plant-insect interactions.

Four enzymes control natural variation in the steroid core of Erysimum cardenolides

The paper identifies four enzymes that control stereochemistry at carbon 5 of cardenolides in Erysimum, showing how natural variation in one enzyme explains structural diversity in these defensive compounds.

Regulation of Arabidopsis polyamine acetylation by NATA1 and NATA2

This study investigates the role of NATA1 and NATA2 in regulating polyamine acetylation in Arabidopsis, showing that NATA2 is heat-inducible and beneficial under heat stress, while its double knockout is lethal.

Knockout mutations of Nicotiana benthamiana defenses reveal the relative importance of acylsugars, nicotine, and a serine protease inhibitor in a natural setting

The paper evaluates the defensive roles of nicotine, acylsugars, and a serine protease inhibitor in Nicotiana benthamiana by comparing plant performance in natural and controlled settings.

Genome and tissue-specific transcriptome of the tropical milkweed (Asclepias curassavica)

This study presents the genome and transcriptome of Asclepias curassavica, revealing tissue-specific gene expression and cardiac glycoside biosynthesis-related genes.

Aphid resistance segregates independently of cardiac glycoside and glucosinolate content in an Erysimum cheiranthoides (wormseed wallflower) F2 population

The paper examines aphid resistance in Erysimum cheiranthoides by analyzing the relationship between defensive metabolites and resistance traits in an F2 population.

Cardiac glycosides protect wormseed wallflower (Erysimum cheiranthoides) against some, but not all, glucosinolate-adapted herbivores

The paper investigates how cardiac glycosides in Erysimum cheiranthoides affect herbivore interactions, finding they protect against some but not all glucosinolate-tolerant herbivores.

Serine proteinase inhibitors from Nicotiana benthamiana, a non-preferred host plant, inhibit the growth of Myzus persicae (green peach aphid)

The paper identifies three serine protease inhibitors from Nicotiana benthamiana that inhibit Myzus persicae growth and survival.

Maize COI1 quadruple-knockout mutants exhibit elevated DELLA protein accumulation, stunted growth, and reduced photosynthetic efficiency

This study investigates maize COI proteins' roles in growth and defense by analyzing mutants, finding that quadruple mutants show stunted growth, reduced photosynthesis, and DELLA protein accumulation.

Horizontally transferred genes as RNA interference targets for aphid and whitefly control

This study identifies horizontally transferred genes (HTGs) in aphids and whiteflies as potential RNAi targets for pest control, showing they can be silenced without harming beneficial insects.

Use of sugarcane mosaic virus for virus-induced gene silencing in maize

This study uses sugarcane mosaic virus to induce gene silencing in maize, showing it can effectively silence endogenous genes and assess the role of JA-Ile metabolism in plant defense.

Acropetal and basipetal cardenolide transport in Erysimum cheiranthoides (wormseed wallflower)

This study investigates cardenolide transport patterns in Erysimum cheiranthoides, finding maternal control of seed cardenolides and root cardenolide profiles determined by aboveground genotype.

Fatty Alcohols, a Minor Component of the Tree Tobacco Surface Wax, Reduce Insect Herbivory

The paper investigates how fatty alcohols in tree tobacco waxes affect insect herbivory, finding they reduce caterpillar growth but not aphid or snail herbivory, and influence egg-laying behavior.

Rapid screening of pest resistance genes in maize using a sugarcane mosaic virus vector

This study uses a sugarcane mosaic virus vector to rapidly test the efficacy of various transgenes against maize pests, finding reduced larval growth in most cases.

Indole-3-glycerolphosphate synthase, a branchpoint for the biosynthesis of tryptophan, indole, and benzoxazinoids in maize

This study identifies three maize IGPS enzymes and their roles in tryptophan, indole, and benzoxazinoid biosynthesis, showing IGPS1 and IGPS3 are involved in defense while IGPS2 may contribute to tryptophan synthesis.

An acylsugar-deficient Nicotiana benthamiana strain for aphid and whitefly research

This paper generates an acylsugar-deficient Nicotiana benthamiana mutant to improve studies of plant-insect interactions and virus transmission.

Specific and conserved patterns of microbiota-structuring by maize benzoxazinoids in the field

This study shows that maize secretes benzoxazinoids (BXs) that shape root and rhizosphere microbiota, with BXs significantly affecting fungal communities across different soil types.

Less Is More: A Mutation in the Chemical Defense Pathway of Erysimum cheiranthoides (Brassicaceae) Reduces Total Cardenolide Abundance but Increases Resistance to Insect Herbivores

This study shows a mutation in Erysimum cheiranthoides reduces total cardenolide abundance but increases resistance to two herbivore species.

Rapid and independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

The paper examines the evolution of chemical defenses in Erysimum plants, finding that ancestral and novel defenses evolved independently without trade-offs.

Cytokinin promotes jasmonic acid accumulation in the control of maize leaf growth.

Cytokinin signaling increases jasmonate biosynthesis, leading to jasmonate accumulation and reduced maize leaf growth.

Characterizing the serotonin biosynthesis pathway upon aphid infestation in Setaria viridis leaves

This study identifies serotonin as a defensive metabolite in Setaria viridis by combining transcriptomic and metabolomic analyses of aphid and caterpillar infestation.

Fusarium graminearum-induced shoot elongation and root reduction in maize seedlings correlate with later seedling blight severity

Ethylene signaling regulates natural variation in the abundance of antifungal acetylated diferuloylsucroses and Fusarium graminearum resistance in maize seedling roots

The paper identifies two antifungal metabolites in maize roots and shows ethylene signaling regulates their ratio, affecting resistance to Fusarium graminearum.
