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 ...

Tropane alkaloids from a Brazilian bark traded as "Catuaba" [PDF]

, 2003
Dichloromethane extracts of a Brazilian bark assigned as Anemopaegma mirandum contained four tropane alkaloids. MS-, UV-, IR-, 1H NMR-data and specific optical rotation allowed the identification of catuabin C and its 7-exo-hydroxy-20-methyl-derivative ...

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

Production of tropane alkaloids during de-differentiation of Scopolia parviflora calli [PDF]

, 2010
The production of tropane alkaloids during differentiation and de-differentiation of Scopolia parviflora calli was studied. Tropane alkaloid production drastically decreased during calli de-differentiation.

Revealing evolution of tropane alkaloid biosynthesis by analyzing two genomes in the Solanaceae family

Nature Communications, 2023
Tropane alkaloids (TAs) are synthesized by some species in Solanaceae. Here, the authors assemble the genomes of two representative TAs producing species, show that gene loss shapes uneven distribution of TAs in Solanaceae, and identify a cytochrome P450

A Golgi‐localized N‐methyltransferase and reversible aldo–keto reductases coordinate dual terminal routes in galanthamine biosynthesis

The Plant Journal, Volume 126, Issue 6, June 2026.
Significant Statement This study identifies LaTMT2, a Golgi‐localized N‐methyltransferase, and three reversible aldo–keto reductases (LaAKR1 and LaAKR3) as key enzymes coordinating the dual terminal routes of galanthamine biosynthesis in Leucojum aestivum.
