Abstract

Fungal pathogens pose significant threats to post-harvest horticultural products, including chillies (Capsicum spp.). This study identified Lasiodiplodia iraniensis as a previously unrecognized causative agent of post-harvest decay in chillies (Capsicum spp.). The pathogen was isolated from diseased chilli fruits and confirmed through subsequent molecular identification via DNA isolation and sequencing. Its internal transcribed spacer (ITS) genetic sequence was submitted to the NCBI database (accession number PP913372). Additionally, the partial translation elongation factor-1 alpha (TEF1) gene was sequenced and submitted to the NCBI database (accession number PQ814684) to further explore its phylogenetic relationships. Subsequently, pathogenicity tests conducted on detached chilli fruits revealed the fungus's aggressive nature, leading to significant decay and confirming Koch's postulates. This highlights the emergence of L. iraniensis as a new threat to chilli quality post-harvest and underscores the need for effective pathogen management strategies to safeguard product quality.

期刊介绍： Physiological and Molecular Plant Pathology provides an International forum for original research papers, reviews, and commentaries on all aspects of the molecular biology, biochemistry, physiology, histology and cytology, genetics and evolution of plant-microbe interactions. Papers on all kinds of infective pathogen, including viruses, prokaryotes, fungi, and nematodes, as well as mutualistic organisms such as Rhizobium and mycorrhyzal fungi, are acceptable as long as they have a bearing on the interaction between pathogen and plant.
