Plant Defensins NaD1 and NaD2 Induce Different Stress Response Pathways in Fungi [PDF]
International Journal of Molecular Sciences, 2016 Nicotiana alata defensins 1 and 2 (NaD1 and NaD2) are plant defensins from the ornamental tobacco that have antifungal activity against a variety of fungal pathogens. Some plant defensins interact with fungal cell wall O-glycosylated proteins. Therefore, we investigated if this was the case for NaD1 and NaD2, by assessing the sensitivity of the three ...

Plant Growth Regulation, 2023 Abstract Biotic and abiotic stresses are main factors limiting crop plants yields and adaptability. Antimicrobial peptides (AMPs) play a pivotal role in plant immune responses to diverse stresses, and hence, becoming novel and essential molecules for studying plant responses to environmental harsh conditions.

Dimerization of Plant Defensin NaD1 Enhances Its Antifungal Activity [PDF]
Journal of Biological Chemistry, 2012 The plant defensin, NaD1, from the flowers of Nicotiana alata, is a member of a family of cationic peptides that displays growth inhibitory activity against several filamentous fungi, including Fusarium oxysporum. The antifungal activity of NaD1 has been attributed to its ability to permeabilize membranes; however, the molecular basis of this function ...

The nad6 gene and the exon d of nad1 are co-transcribed in wheat mitochondria
Current Genetics, 1993The exon d of nad1 is located 993 bp upstream of the nad6 gene in the wheat mitochondrial genome. Transcription analyses of both sequences (nad1 exon d and the nad6 gene) were done by Northern hybridization using RNA from wheat seedlings and tissue cultures derived from immature embryos. A complicated pattern was generated with a probe including exon d

Permeabilization of Fungal Hyphae by the Plant Defensin NaD1 Occurs through a Cell Wall-dependent Process [PDF]
Journal of Biological Chemistry, 2010 The antifungal activity of the plant defensin NaD1 involves specific interaction with the fungal cell wall, followed by permeabilization of the plasma membrane and entry of NaD1 into the cytoplasm. Prior to this study, the role of membrane permeabilization in the activity of NaD1, as well as the relevance of cell wall binding, had not been investigated.

NaD1, a plant defensin isolated from the flowers of Nicotiana alata, is a cationic antimicrobial peptide (CAP) that displays potent antifungal activity against a variety of pathogenic fungi and tumor cells by attacking cell membranes. Specific interactions between NaD1 and phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2), as well as NaD1 and ...

Forty-six species of diverse land plants were investigated by sequencing for their intron content in the mitochondrial gene nad1. A total of seven introns, all belonging to group II, were found, and two were newly discovered in this study. All 13 liverworts examined contain no intron, the same condition as in green algae. Mosses and hornworts, however,
