Genome-wide identification and characterization of polygalacturonase gene family in linseed (Linum usitatissimum L.) and comparative expression in its wild relative (Linum bienne) upon bud fly infestation

The present study identified 42 genes in linseed, with four key genes showing potential for inhibiting bud fly feeding by altering cell walls. These findings provide a foundation for future breeding programs to enhance pest resistance in linseed crops.
