Review: Till death do us pair: Co-evolution of plant–necrotroph interactions
Plant Science Research WeeklyThis interesting and well-written review by Derbyshire and Raffaele takes a step back from the molecular interactions between plant and pathogen and discusses them in light of co-evolutionary processes. The review starts with a useful introduction and definition of concepts about “robustness” in…
Spotlight: Super-pangenomes for improved breeding
Plant Science Research WeeklySometimes more really is better, and I think it’s safe to say that when it comes to genomic information, more is better. Here, Raza et al. highlight the great value of super-pangenomes. A pan-genome is defined as the entire set of genes within a species, created by combining sequences of many individuals.…
Chloroplast proteostasis prevents aggregation of Huntington’s disease-causing human polyQ protein
Plant Science Research WeeklyCertain human neurodegenerative disorders are caused by aggregation of disordered proteins. In particular, Huntington’s disease is caused by aggregation of a protein called huntingtin, which contains long stretches of glutamine (Q). Llama et al. observed that proteins with long stretches of glutamine…
Altering chloroplast biogenesis leads to increased yields in rice
Plant Science Research WeeklyTranscription of chloroplast genes is carried out by the plastid encoded polymerase (PEP) with help from PAPs (PEP-associated proteins). PAP3 is important for chloroplast development in Arabidopsis thaliana and Nicotiana benthamiana, however its role in crops has not been fully elucidated. Here Seo et…
