Abstract Gene functional descriptions offer a crucial line of evidence for candidate genes underlying trait variation. Conversely, plant responses to environmental cues represent important resources decipher gene function and subsequently provide molecular targets improvement through editing. However, biological roles large proportions across the phylogeny are poorly annotated. Here we describe Joint Genome Institute (JGI) Plant Atlas, an updateable data resource consisting transcript...
Significance Many insects release volatile terpenes for chemical communication. However, the biosynthetic origin and evolution of these infochemicals are mostly unknown. We show that harlequin bug, Murgantia histrionica , a stink bug pest (Hemiptera) crucifer crops, produces terpene aggregation pheromone by an enzyme is unrelated to microbial plant synthases. M. synthase activity highly sex- tissue-specific makes sesquiterpene alcohol, so far unknown in animals, as precursor. The evolved...
Switchgrass (Panicum virgatum L.), a perennial C4 grass, represents an important species in natural and anthropogenic grasslands of North America. Its resilience to abiotic biotic stress has made switchgrass preferred bioenergy crop. However, little is known about the mechanisms resistance against pathogens herbivores. Volatile compounds such as terpenes have activities plant direct indirect defense. Here, we show that leaves emit blends monoterpenes sesquiterpenes upon feeding by generalist...
Diterpenoids constitute a diverse class of metabolites with critical functions in plant development, defense, and ecological adaptation. Major monocot crops, such as maize (Zea mays) rice (Oryza sativa), deploy blends specialized diterpenoids core components biotic abiotic stress resilience. Here, we describe the genome-wide identification functional characterization stress-related diterpene synthases (diTPSs) dedicated bioenergy crop switchgrass (Panicum virgatum). Mining allotetraploid...
Abstract Carrot ( Daucus carota L.) is an important root vegetable crop with high nutritional value, characteristic flavor, and benefits to human health. D. tissues produce essential oil that rich in volatile terpenes plays a major role carrot aroma flavor. Although terpene composition represents critical quality attribute of carrots, little known about the biosynthesis this crop. Here, we functionally characterized 19 synthase (TPS) genes orange (genotype DH1) compared tissue-specific...
Arabidopsis thaliana maintains a complex metabolism for the production of secondary or specialized metabolites. Such metabolites include volatile and semivolatile terpenes, which have been associated with direct indirect defensive activities in flowers leaves. In comparison, structural diversity function terpenes roots has remained largely unexplored despite substantial number root-expressed genes terpene synthase (TPS) gene family. We show that five TPSs an expanded subfamily-a type clade...
SUMMARY Specialized diterpenoid metabolites are important mediators of plant–environment interactions in monocot crops. To understand metabolite functions plant environmental adaptation that ultimately can enable crop improvement strategies, a deeper knowledge the underlying species‐specific biosynthetic pathways is required. Here, we report genomics‐enabled discovery five cytochrome P450 monooxygenases (CYP71Z25–CYP71Z29) form previously unknown furanoditerpenoids bioenergy Panicum virgatum...
ABSTRACT Gene functional descriptions, which are typically derived from sequence similarity to experimentally validated genes in a handful of model species, offer crucial line evidence when searching for candidate that underlie trait variation. Plant responses environmental cues, including gene expression regulatory variation, represent important resources understanding function and targets plant improvement through editing other biotechnologies. However, even after years effort numerous...
Abstract Specialized diterpenoid metabolites are important mediators of stress resilience in monocot crops. A deeper understanding how species-specific diterpenoid-metabolic pathways and functions contribute to plant chemical defenses can enable crop improvement strategies. Here, we report the genomics-enabled discovery five cytochrome P450 monooxygenases (CYP71Z25-29) that form previously unknown furanoditerpenoids bioenergy switchgrass ( Panicum virgatum ). Combinatorial pathway...
