Unraveling the Parablechnum cordatum (Blechnaceae: Polypodiopsida) complex puzzle

Abstract Parablechnum cordatum (Blechnaceae) exhibits significant morphological variability, with many species considered as its synonyms, and is treated as a species complex by several authors. In this study, we offer a comprehensive revis...

Chemical composition, antioxidant and antimicrobial potential of essential oils from different parts of Daphne mucronata Royle

Abstract This research work was executed to determine chemical composition, anti-oxidant and anti-microbial potential of the essential oils extracted from the leaves and stem of Daphne mucronata Royle. From leaves and stem oils fifty-one di...

The Role of Iron in Phytopathogenic Microbe–Plant Interactions: Insights into Virulence and Host Immune Response

Iron is an essential element required for the growth and survival of nearly all forms of life. It serves as a catalytic component in multiple enzymatic reactions, such as photosynthesis, respiration, and DNA replication. However, the excess...

<i>Carthamus tinctorius</i> Suppresses LPS-Induced Anti-Inflammatory Responses by Inhibiting the MAPKs/NF-κB Signaling Pathway in HaCaT Cells

This study aimed to elucidate the anti-inflammatory activity of C. tinctorius leaves by measuring inflammatory parameters such as nitric oxide (NO) production and mRNA expression of iNOS, interleukin-6 (IL-6), and IL-1β in lipopolysaccharid...

Integrative omics analysis on phytohormones involved in oil palm seed germination

Abstract Background Heat treatment is widely used to break dormancy for seed germination and phytohormones could be deeply involved. However, effect of heat treatment on phytohormone related genes/proteins/metabolites and possible relations...

O monitoramento de macrófitas da represa Alagados um reservatório artificial de água que abastece parcialmente a população do município de Ponta Grossa-PR se faz necessário, uma vez que resíduos urbanos, bem como dejetos de áreas rurais, sã...

Incidence of the fermentation temperature on the total fatty acid evolution

This work aims to study the incidence of the fermentation temperature on the total fatty acid evolution and its potential impact on the fermentation stops....

A large deletion conferring pale green leaves of maize

Abstract Background The structural basis of chloroplast and the regulation of chloroplast biogenesis remain largely unknown in maize. Gene mutations in these pathways have been linked to the abnormal leaf color phenotype observed in some mu...

Evolution of Tandem Repeats Is Mirroring Post-polyploid Cladogenesis in Heliophila (Brassicaceae)

The unigeneric tribe Heliophileae encompassing more than 100 Heliophila species is morphologically the most diverse Brassicaceae lineage. The tribe is endemic to southern Africa, confined chiefly to the southwestern South Africa, home of tw...

AY-WB Phytoplasma Secretes a Protein That Targets Plant Cell Nuclei

The fully sequenced genome of aster yellows phytoplasma strain witches' broom (AY-WB; Candidatus Phytoplasma asteris) was mined for the presence of genes encoding secreted proteins based on the presence of N-terminal signal peptides (SP). W...

Mitigation of salinity stress in canola plants by sodium nitroprusside application

Salinity is a global issue threatening land productivity and food production. The present study aimed to examine the role of sodium nitroprusside (SNP) on the alleviation of NaCl stress on different parameters of canola (Brassica napus L.) ...

Analysis of taxonomic distinctness and priority conservation areas as a basis for heritage enhancement of floristic diversity: the case of the ‘hotspot’ of the islands of Numidia (North-eastern Algeria)

The identification of priority conservation areas (PCA) plays an important role in biodiversity conservation, but uncertainties create challenges for conservation planning. The objective was to test a method based on 'taxonomic distinctness...

No hay diferencias en la diversidad genética entre arbustos de Cotoneaster franchetii (Rosaceae) de rangos nativos y no nativos.

No hay diferencias en la diversidad genética entre arbustos de Cotoneaster franchetii (Rosaceae) de rangos nativos y no nativos. La diversidad genética de los arbustos de Cotoneaster franchetii es similar entre los rangos de distribución na...
