Background: Etiological diagnosis is essential in bronchiectasis for proper management as improperly managed bronchiectasis often worsens over a period of time. Etiological diagnosis of bronchiectasis depends on history, clinical features and HRCT scan. Recognition of the pattern of involvement & distribution of bronchiectasis in HRCT is useful to outline the differential diagnosis, map the complications and, hence, guide the further management in bronchiectasis.

- The study investigates the role of primary metabolites in the interaction between Brassica napus (canola) and the pathogen Plasmodiophora brassicae, focusing on clubroot resistance.
- The researchers compared clubroot-resistant and susceptible canola lines over three time points post-inoculation and analyzed various metabolites, highlighting the differential accumulation of amino acids and organic acids between resistant and susceptible lines.
- Key findings included the higher levels of salicylic acid in resistant lines and the potential role of fatty acids and specific genes in enhancing resistance against clubroot disease.
C2H2-zinc finger (C2H2-ZF) genes are involved in various biological processes in plants including stress response; however, they lack characterization in . We identified 267 C2H2-ZF genes in and deciphered their physiological properties, subcellular localization, structure, synteny, and phylogeny and investigated the expression of 20 genes in response to different stresses and phytohormone treatments. The 267 genes were distributed on 19 chromosomes; phylogenetic analysis categorized them into five clades.

- The study identified 43 Biotin Carboxyl Carrier Protein (BCCP) genes across five Brassica species, with varying counts of homologs in each species.
- Phylogenetic analysis revealed five classes of BCCP genes, all containing stress-related elements in their promoter regions, and gene duplication was noted in certain species, highlighting mechanisms of gene family expansion.
- Functional analysis of selected BnaBCCP genes suggested their significant roles in responding to various biotic and abiotic stresses, providing insights for improving stress tolerance in canola.
Clubroot disease caused by Plasmodiophora brassicae is one of the serious threats to canola (Brassica napus L. subsp. napus) production.
