Deciphering Cold Stress Resilience: Multiomics Insights in Contrasting Wheat Genotypes From the Western Himalayas

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4577-4598, July 2026.
ABSTRACT Cold stress threatens wheat productivity, particularly in regions with extreme climatic conditions. To elucidate the molecular mechanisms underlying wheat's response to cold stress, we performed a multiomics analysis integrating lipidomics, transcriptomics, proteomics and metabolomics.

The Early Response to Urea, Nitrate, or Ammonium and Iron Resupply in Tomato Roots Highlights the Induction of FER, bHLHs, UMAMITs, and MATEs

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Depending on the nitrogen (N) form available to roots, plants activate different transcriptional and metabolic pathways; this can consequently translate into differences in the composition and release of root exudates. To address the existing knowledge gap regarding the relationship between the availability of Iron (Fe) and different N forms ...

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, Volume 24, Issue 6, Page 4139-4158, June 2026.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Tropinone synthesis via an atypical polyketide synthase and P450-mediated cyclization

Nature Communications, 2018
Tropinone is an intermediate in the biosynthesis of tropane alkaloids. Here, the authors discovered the enzymes AbPYKS and AbCYP82M3, a non-canonical polyketide synthase and a cytochrome P450, that work sequentially to form tropinone from N-methyl-Δ1 ...
