The non-specific lipid transfer protein N5 of Medicago truncatula is required for efficient nodulation during symbiosis with N-fixing rhizobia

, 2013
Transgenic adventitious hairy roots carrying a hairpin construct (MtN5hp) for MtN5 silencing are impaired in nodulation, showing a 50% of reduction in the number of nodules compared with inoculated control roots (Pii et al., 2009).

A factorial multi‐layer analysis reveals non‐additive sulfur–iron interactions shaping metabolic and transcriptional responses in durum wheat

New Phytologist, Volume 252, Issue 1, Page 192-208, October 2026.
Working model of S‐dependent Fe stress integration in durum wheat. S availability acts as the main factor defining the metabolic and transcriptional state of the plant, whereas Fe mainly affects the intensity of these responses. This is particularly evident for OAS, methionine, citrate and asparagine, which accumulated most strongly under combined S ...

Novel Catalytically-Inactive PII Metalloproteinases from a Viperid Snake Venom with Substitutions in the Canonical Zinc-Binding Motif

Toxins, 2016
Snake venom metalloproteinases (SVMPs) play key biological roles in prey immobilization and digestion. The majority of these activities depend on the hydrolysis of relevant protein substrates in the tissues.

Is mineral nutrient concentration of soybean, maize, and wheat grain affected by cropping sequence and agronomic management?

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Producers in the Argentine Pampas often fail to fully replenish the nutrients extracted by crops, leading to unsustainable soil fertility management. The objectives of this study were to (i) evaluate grain yield, mineral nutrient concentration, and extraction for maize (Zea mays L.), wheat (Triticum aestivum L.), and soybean (Glycine max L ...

The alga Bryothamnion seaforthii contains carbohydrates with antinociceptive activity

Brazilian Journal of Medical and Biological Research, 2004
Bryothamnion seaforthii, a red alga common to the Northeastern coast of Brazil, was used to prepare the protein fraction F0/60 by ammonium sulfate precipitation. The chromatography of F0/60 on DEAE-Sephadel column resulted in two lectin fractions, PI and

Conformational dissection of a viral intrinsically disordered domain involved in cellular transformation. [PDF]

PLoS ONE, 2013
Intrinsic disorder is abundant in viral genomes and provides conformational plasticity to its protein products. In order to gain insight into its structure-function relationships, we carried out a comprehensive analysis of structural propensities within ...

Non‐Metastatic Squamous Cell Carcinoma of the Oropharynx: Primary Surgery or (Chemo)radiotherapy?

Head &Neck, Volume 48, Issue 9, Page 2541-2556, September 2026.
ABSTRACT Background In patients with locally advanced, non‐metastatic oropharyngeal squamous cell carcinoma (OPSCC), surgery‐based and nonsurgical treatment approaches have not been adequately compared in randomized Phase III clinical trials. Current clinical guidelines recommend various surgical and nonsurgical strategies across disease stages for ...

Chloroplast acetyl-CoA carboxylase activity is 2-oxoglutarate–regulated by interaction of PII with the biotin carboxyl carrier subunit [PDF]

, 2010
The PII protein is a signal integrator involved in the regulation of nitrogen metabolism in bacteria and plants. Upon sensing of cellular carbon and energy availability, PII conveys the signal by interacting with target proteins, thereby modulating ...

Natural variation in the atypical resistance gene Ptr confers broad‐spectrum neck blast resistance in rice

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Neck blast (NB), caused by Magnaporthe oryzae, infects rice (Oryza sativa L.) and reduces yield. Knowledge of NB resistance remains limited due to the lack of reliable resistance evaluation methods. Here, we applied a newly established neck injection method and performed a genome‐wide association study (GWAS) on 335 diverse accessions from the
