DNA Methylation Shapes Seed‐Borne Microbiome and Proteome Responses During Early Maize‐Beneficial Bacteria Interactions

Plant, Cell &Environment, EarlyView.
ABSTRACT Microorganism and plant interactions are crucial for development and environmental adaptation. Plant growth promoting bacteria enhance agricultural productivity in a sustainable manner, while epigenetic modifications such as DNA methylation regulate gene expression and adaptive responses.

Influence of salicylic acid nano-formulation on expression of peroxidase (113-114) genes and peroxidase and phenylalanine ammonia lyase in wheat cultivar susceptible to Heterodera filipjevi

Journal of Crop Protection, 2018
The effects of salicylic acid (SA) nano-formulation on expression of peroxidase (113-114) genes and peroxidase and phenylalanine ammonia lyase (PAL) were investigated in wheat cultivar (Bezostaya) susceptible to Heterodera filipjevi.

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Molecular cloning and sequence analysis of a phenylalanine ammonia-lyase gene from dendrobium. [PDF]

PLoS ONE, 2013
In this study, a phenylalanine ammonia-lyase (PAL) gene was cloned from Dendrobium candidum using homology cloning and RACE. The full-length sequence and catalytic active sites that appear in PAL proteins of Arabidopsis thaliana and Nicotiana tabacum are

Phenylalanine and Tyrosine as Exogenous Precursors of Wheat (Triticum aestivum L.) Secondary Metabolism through PAL-Associated Pathways

Plants, 2020
Reacting to environmental exposure, most higher plants activate secondary metabolic pathways, such as the metabolism of phenylpropanoids. This pathway results in the formation of lignin, one of the most important polymers of the plant cell, as well as a ...

Identification and Functional Characterization of Isoflavone synthase Gene Family in Pea (Pisum sativum): The Entry Point to Pisatin Biosynthesis

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Isoflavone synthase (IFS), a cytochrome P450 monooxygenase of the CYP93C subfamily, catalyzes the conversion of flavanones into isoflavones, the first committed step in the biosynthesis of isoflavonoid phytoalexins. In pea (Pisum sativum L.), the phytoalexin pisatin plays a pivotal role in defense against pathogens.

Growth characteristics and phenylalanine ammonia-lyase activity in peach grafted on different Prunus spp.

Biologia Plantarum, 2014
Phenylalanine ammonia lyase (PAL) is a key enzyme in the phenylpropanoid pathway responsible for biosynthesis of many secondary metabolites, such as anthocyanins, flavanols, and lignins. The objective of this work was to determine the effect of different

ARF6 integrates auxin and gibberellin signaling to promote stone cell lignification in pear via the HB49‐MYB169 module

New Phytologist, Volume 250, Issue 6, Page 3747-3768, June 2026.
Summary Stone cells originate from secondary cell wall thickening and contain abundant lignin. Their excessive accumulation compromises pear fruit quality, yet the endogenous hormonal mechanisms governing stone cell formation remain unclear. Here, co‐expression network analysis using transcriptome data – the flesh of 206 sand pear accessions sampled at
