Increasing healthcare costs, limited healthcare resources, an aging population, and lifestyle-related diseases make wound management a growing clinical, social, and economic burden. This case series investigated the use of a novel, biocompatible, polymer-based transforming powder dressing (TPD) that transforms in situ to a shape-retentive wound matrix upon hydration for treating wounds of various etiologies.In this institutional review board-approved single-center retrospective case series, the researchers evaluated various acute and chronic wounds treated with TPD over a period of 2 years.

Article Synopsis
  • Phytophthora root rot caused by the pathogen Phytophthora capsici significantly affects chile pepper production, prompting a study to find genetic resistance in 157 Capsicum genotypes.
  • Using genome-wide association studies (GWAS) with over 55,000 SNP markers, researchers identified 330 significant markers linked to resistance, with some markers indicating more durable resistance across multiple plant isolates.
  • The findings will support future breeding programs and marker-assisted strategies to enhance resistance against Phytophthora root rot in chile peppers, focusing on specific candidate genes associated with resistance traits.

Background: Genomewide prediction estimates the genomic breeding values of selection candidates which can be utilized for population improvement and cultivar development. Ridge regression and deep learning-based selection models were implemented for yield and agronomic traits of 204 chile pepper genotypes evaluated in multi-environment trials in New Mexico, USA.

Results: Accuracy of prediction differed across different models under ten-fold cross-validations, where high prediction accuracy was observed for highly heritable traits such as plant height and plant width.

Article Synopsis
  • The study investigates the impact of different rating systems on identifying quantitative trait loci (QTL) related to resistance against a harmful pathogen affecting pepper crops.
  • Two methods were compared, revealing that the Bosland and Lindsey system better detected specific QTL than the Black system, although each had unique strengths in identifying certain QTL.
  • Resistance inheritance patterns showed a 7:9 segregation ratio, suggesting a complex genetic interaction influenced by incomplete gene action and the characteristics of the tested population.
