No need for shuffling: Sexual reproduction without crossovers results in clonal reproduction
Plant Science Research WeeklyMeiosis, the process of generating gametes in sexually reproducing organisms, typically includes the shuffling of genetic information between homologous chromosomes from each parent. This process leads to the exchange of DNA between these chromosomes, ultimately contributing to greater genetic diversity…
Autophagy “eats” paternal mitochondria in rice
Plant Science Research WeeklyIn plants, maternal inheritance of mitochondria is a common phenomenon, resulting from the elimination of paternal mitochondrial DNA during pollen development or by the degradation of paternal mitochondria after fertilization. A recent study by Aini et al. provides new insights into the fate of paternal…
How salicylic acid switches plant defence genes on and off
Plant Science Research WeeklySalicylic acid (SA) is a plant hormone that plays a central role in defence against pathogens. In Arabidopsis thaliana, SA is perceived by NPR1, NPR3 and NPR4, but how these receptors regulate defence gene expression has remained unclear. Peng et al. show how SA promotes transcriptional activation through…
Do roots rely on damage signaling for effector-triggered immunity?
Plant Science Research WeeklyPlant immunity has two well-studied layers: pattern-triggered immunity (PTI), activated when plasma membrane-localized receptors recognize microbe-associated molecular patterns (MAMPs), and effector-triggered immunity (ETI), mediated by intracellular nucleotide-binding leucine-rich repeat (NLR) receptors…
Using eDNA from leaf and flower surfaces to assess plant-arthropod interactions
Plant Science Research WeeklyBiodiversity monitoring has become increasingly critical as climate change and anthropogenic land use have escalated, but recording and quantifying interspecies interactions in the field is time- and work-intensive. Environmental DNA, or eDNA, has attracted interest particularly for use in analyzing…

WWR Full PostReview: Old genes for new purposes: how gene co-option reshapes plant diversity
The diversity in plants’ adaptations and evolution is vast. One driver of this variety gaining traction in evolutionary studies is gene co-option, or “tinkering”, the ability to repurpose existing genes for new purposes.…
Review: Plant digital twins, the future of crop production
Plant Science Research WeeklyImagine how cool it would be if, just like we check weather apps before going out, we could “grow” a plant in our computer before planting it into our backyard, in order to predict its future success. Pauli et al. discuss this possibility through the use of Digital Twins (DTs), virtual plants that…
Benzaldehyde reductases complete the salicylic acid biosynthesis puzzle
Plant Science Research WeeklyBenzyl alcohol is a volatile compound and the scent molecule of several seed plants. It also can be converted to benzyl benzoate, which is one of the routes to salicylic acid (SA) production in plants. The flowers of Petunia hybrida are wonderful factories of benzyl alcohol, prompting Lee et al. to use…
Oxygen: A hidden developmental cue in leaf morphogenesis
Plant Science Research WeeklyOxygen is always considered something living forms need to survive. But wait, its role is beyond just respiration. Would you believe if I told you oxygen guides the development of young leaves? A recent study by Panicucci et al. reveals that oxygen acts as a signalling molecule, affecting cell proliferation…
