A virtual nodule environment (ViNE) of metabolic integration during symbiotic nitrogen fixation (bioRxiv)

Genetic and molecular studies have revealed a complex exchange of signals and metabolites accompanying the development and process of symbiotic nitrogen fixation. Clearly, the photosynthesis-capable plant provides fixed carbon to the bacterial symbiont, which uses some of this energy for its core metabolism…

Cannabis glandular trichomes alter morphology and metabolite content during flower maturation ($) (Plant J)

The therapeutic and recreational applications of Cannabis sativa (Cs) attract public and clinical interest thanks to its secondary metabolites (cannabinoids and terpenes) synthesized and stored in glandular trichomes, hair-like epidermal protrusion densely concentrated in the flowers. Little is known…

Male sterility in maize after transient heat stress (Plant Physiol)

The corn we eat is a seed, which is a product of fertilization. It is widely known that corn yields are highly susceptible to abiotic stress conditions that occur during the repdroductive stage of development. Begcy et al. used a metabolomic / transcriptomic approach to understand why transient heat…

Diverse metabolites across maize GWAS panel for dissecting maize genetic architecture (Plant Cell)

Plants can produce metabolites that are directly involved in various biological pathways. Identifying variations of specific metabolites in different genotypes would facilitate the understanding underlying complex genetic architecture of maize. One of most representative natural diversity panels, the…

Untargeted metabolomics reveals host plant chemistry before and after pea aphid infestatation (Front. Plant Sci)

Pea aphids are genetically diverse, with different biotypes (or “host races”) having different host plant preferences. Sanchez-Arcos et al. reveal several relationships between plant metabolite production and the possibility of colonization of certain aphid host races. Using UHPLC- MS analysis of…

Review: The metabolic response to drought (J Exp Bot) ($)

Understanding environmental stress in plants is undoubtedly important due to the consequences of climate change in crop productivity and survival of plants. Metabolomics based on liquid chromatography and gas chromatography coupled to mass spectrometry (LC-MS, GC-MS) allows an understanding of the metabolic…

Mathematical modeling approaches in plant metabolomics

Mathematical modeling, as a series of useful methods for functional and causal interpretation of experimental high-throughput studies, enables us to explore the complex field of plant metabolism. The application of differential equations as a mathematical method has been developed and reviewed for decades…
