Pathotype characterization of isolates collected from pea breeding nurseries.

Introduction: Drechsler is an oomycete pathogen that affects legume crops, causing root rot, a severe disease of peas ( L.) worldwide. While significant research progress has been made in breeding pea-resistant varieties, there is still a need for a deeper understanding of the diversity of pathogen populations present in breeding nurseries located in various legume-growing regions around the world.

Fine mapping of Ae-Ps4.5, a major locus for resistance to pathotype III of Aphanomyces euteiches in pea.

QTL mapping and recombinant screening confirmed the major effect of QTL Ae-Ps4.5 on pea resistance to pathotype III of Aphanomyces euteiches and fine-mapped the QTL to a 3.06-Mb interval.

Five Regions of the Pea Genome Co-Control Partial Resistance to , Tolerance to Frost, and Some Architectural or Phenological Traits.

Evidence for reciprocal links between plant responses to biotic or abiotic stresses and architectural and developmental traits has been raised using approaches based on epidemiology, physiology, or genetics. Winter pea has been selected for years for many agronomic traits contributing to yield, taking into account architectural or phenological traits such as height or flowering date. It remains nevertheless particularly susceptible to biotic and abiotic stresses, among which and frost are leading examples.

Meroterpenoids? A historical and critical review of this biogenetic determinant.

In its original definition, meroterpenoids refer to substances of mixed biosynthesis including a terpenoid part. The number of compounds fulfilling this criterion is huge, and almost from the beginning, exclusions were made, more or less, explicitly stated. The concept is well accepted in the microorganism domain, where biosynthetic studies are advanced, while in the plant domain, meroterpenes and meroterpenoids randomly appear.
