1/8 🌱🔬 Exciting developments in biology!

Our research investigates the 24-hour, biological clock in plants, now using absolute protein quantification thanks to Uriel Urquiza’s hard work with me, Karen Halliday and Nacho Molina.

It points to some simple conclusions, some unknown regulatory mechanisms and the promise of a whole new level of understanding. 🧵

Decoding the cellular basis of floral fragrance

Researchers have created the 1st single-cell gene expression map of Prunus mume petals. Using advanced RNA sequencing, they identified 6 cell types driving floral scent production, pinpointing key genes. This breakthrough enhances understanding of fragrance biosynthesis, offering potential for breeding aromatic plants & innovating in #horticulture & perfumery.

New Insights into Flowering Regulation

An international team uncovered how carbon and nitrogen signals regulate flowering in Arabidopsis thaliana. The study reveals that these pathways converge on FLOWERING LOCUS C to fine-tune flowering time, offering insights to develop resilient, resource-efficient crops for sustainable agriculture.

Agricultural plastic pollution reduces soil function

A new study reveals that plastic, even under best practices, contaminates soils with macro- and microplastics, harming critical soil functions. Sampling 12 California farms, researchers found significant plastic debris. To protect soil health and productivity, biodegradable alternatives to plastic mulch are urgently needed.

Secrets of the Corpse Flower Revealed

The corpse flower’s rare, short-lived blooms emit a pungent scent to attract pollinators, fueled by heat from its spadix. Researchers uncovered genes driving heat and odor production, linking sulfur metabolism and amino acids like methionine and putrescine to its smell. This study advances understanding of thermogenesis and pollination in plants.

Previously unknown perception mechanism discovered in plants

Plants use pigments called phytochromes to sense light and temperature, adjusting growth and metabolism accordingly. Rising temperatures, however, disrupt these processes. Researchers found that under red light, phytochrome responses vary with temperature & light intensity, potentially allowing precise control of plantGene activation for biotechnology.

A 23-year study found that barley grown under organic farming conditions developed unique genetic adaptations, enhancing resilience to nutrient and water deficiencies.

Unlike conventionally farmed barley, which became genetically uniform, organic barley maintained genetic diversity, aiding adaptation to environmental changes.

📢 #jobopening #plantsci #Bordeaux
Our #FDFE team @INRAE_BFP is recruiting an engineer in molecular biology / genomics (2 years contract) to work on the regulation of gene expression during tomato fruit development 🌱🍅🧬🔬

More info here 👇
jobs.inrae.fr/en/ot-21925

INRAE JobsEngineer in molecular biology / genomicsYou will join the “Fruit Development, Flowering and Environmental contraints” team, part of the “Fruit Bioloy & Pathology” lab. The lab is located on the INRAE campus of Villenave d’Ornon, in the south suburb of Bordeaux. You will be involved in the TomENCODE ANR project which aims to elucidate the mechanisms involved in the regulation of gene expression during endoreduplication in the tomato fruit. To achieve this goal, we use various techniques based on next-generation sequencing (NGS) in order to understand how changes in chromatin organisation (ATAC-seq, CUT&RUN, CUT&TAG) affect RNA expression (mRNA-seq, smallRNA-seq, single nuclei RNA-seq). You will be involved mainly in the production of omics datasets and their first-level analysis. More specifically, your role will be to actively participate in: - Taking care of plant cultures in the green house and collecting biological samples for omics analyses. - Analysing ploidy by flow cyometry and performing nuclei sorting using a cell sorter - Preparing and performing experiments aimed at analysing chromatin (ATAC-seq, CUT&RUN, CUT&TAG, …) - Performing purifications (RNA, DNA, proteins) from the biological samples and performing transcriptomic analyses - Collecting, saving and archiving NGS sequencing datasets - Performing quality controls and first-level bioinformatic analysis of NGS datasets - You may also be involved in the following activities: cloning, protein purification, transgenic plants transformation, molecular analysis and phenotyping of plants. Environment : You will benefit from a stimulating environment on the INRAE campus that hosts several excellent laboratories focused on plant biology, plant pathology and environmental sciences. Greenhouses and facilities for metabolomics and imaging are present on campus. Flow cytometry and genomic facilities are located within 15min from the lab. You will benefit from the scientific expertise of your direct supervisors, Nathalie Gonzalez and Pascal Martin, and from the expertise of the members of the FDFE teams in plant growth and phenotyping, endoreduplication, cellular biology, functional genomics, cellular imaging and bioinformatics. Located at the heart of the world-renowned wine region, Bordeaux has a lot to offer with its rich history, international level university campus and a thriving cultural scene!
