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.

This study identifies an aphid protein, AAF1, that manipulates plant autophagy to enhance aphid survival and plant growth.

The paper shows that aphid microRNAs and argonaute protein are translocated into their obligate endosymbiont Buchnera, suggesting a new regulatory mechanism between host and symbiont.

This study identifies 2-oxoglutarate-dependent dioxygenases involved in cardenolide biosynthesis in Erysimum cheiranthoides and characterizes their enzymatic functions.

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

This study overexpresses NPQ genes in C4 plant Setaria viridis to compare photoprotection mechanisms with C3 plants, finding shared and unique traits that could improve crop resilience.

This study overexpresses NPQ-related genes in Setaria viridis to assess NPQ acclimation rates, finding faster NPQ induction but no photosynthetic benefit.

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

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.

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.

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

This study compares the toxicity of Vip3A in vitro and in planta against lepidopteran pests, finding no correlation between the two and highlighting host plant adaptation effects.

This study shows that silencing cathepsin L in aphids reduces their protein content and affects ladybug growth, highlighting the importance of prey nutritive value in RNAi-based pest control.

The paper presents a high-quality chromosome-level genome assembly of the corn leaf aphid, providing insights into its biology and potential applications in research.

The paper uses metabolome-scale GWAS to identify genetic loci controlling maize specialized metabolites, revealing chemical diversity and gene-metabolite associations.

This study shows that the green peach aphid uses rapid transcriptional changes of duplicated genes to colonize diverse host plants without genetic specialization.

This study identifies rapid gene and metabolite changes in maize leaves after caterpillar feeding, showing early defense responses and the role of benzoxazinoids and jasmonic acid pathways.
