A gene with a thousand alleles: The hyper-variable effectors of plant-parasitic nematodes

Sonawala et al. describe how the HYP genes in plant-parasitic nematodes can harbor thousands of alleles. They elucidate the “rules” underlying variation in the hyper-variable domain (HVD) of HYPs and...

I am super excited that our paper (my 1st 1st author paper 🥹) in #pnas is finally out! We found that the #chytrid s Bd & Bsal have 2-speed genomes previously only found in #plant #pathogens.Also exciting: #transposons appear to be shaping their genomes & drive pathogenicity. 1/2

Our new paper is published in #pnas on the 2-speed genomes of #chytrid pathogens of amphibians (Bd and Bsal). Repetitive sequence inc. transposons appears to be shaping their genomes and driving their pathogenicity pnas.org/doi/10.1073/pnas.22… @theresa_wacker

Mutual potentiation between surface receptor- and intracellular receptor-mediated immunity, also in mammals cell.com/cell/fulltext/S0092… @sardineboy_DING @BrunoNgou @HeeKyungAhn1

NLRP12-PANoptosome activates PANoptosis and pathology in response to heme and PAMPs

NLRP12 is an immune sensor that activates cell death and inflammation when it senses heme and pathogen-associated molecular danger signals indicative of hemolytic diseases.

WeiTsing, a pericycle-expressed ion channel, safeguards the stele to confer clubroot resistance

WeiTsing, an ER-localized calcium-permeable channel, enables pericycle to prevent Plasmodiophora brassicae colonization in stele, thereby conferring a broad-spectrum clubroot resistance.

This really is no joke. People act like toxic environments in research is the price we have to pay for genius to succeed. But have we considered that there might be more success in positive work environments where everyone feels properly supported? /1 nature.com/articles/d41586-0…

A mental-health crisis is gripping science — toxic research culture is to blame

Nature - With researchers reporting high rates of anxiety and depression, calls are growing to fundamentally change science before it’s too late.

and one little teaser: research on this fascinating topic is still continuing in #theustunlab @LanginGautier is preparing his manuscript explaining the last puzzle pieces of how the proteasome coordinates the tradeoff btw. growth & defense, surprise photosynthesis plays a role 😅 – at Bochum, Germany
