Ok now for a real kicker—the oldest nematode known from fossil record was a plant-parasitic one that lived in stomatal chambers of this same plant! Discovered and imaged here by George Poinar and Hans Kerp from Rhynie Chert from around 400 mya. brill.com/view/journal...

Fig. 1. Representation of molting of fourth-stage juveniles (J-4s) of Paratylenchus nanus type B when exposed to root exudates of field pea cultivars. Molting was assessed based on the casting of the outer cuticle along with stylet and vulva formation in the nematodes. A, Fourth-stage juvenile pin nematodes in first observation point (Day 2) with no stylet after they were placed in root exudates of susceptible cultivar Arcadia. B, Initiation of stylet formation in an early phase (Day 6) as prominent lines were observed in the mouth part of J-4 kept in root exudates of cultivar Arcadia. C, Anterior part of the nematode with a fully developed stylet (Day 15) showing the release of outer cuticle in the mouth region. D, Posterior part of the tail with shed cuticle attached (Day 22) to the body as the fourth-stage larva enters near the final stage of molting.

New paper out! 🌱
Plant defence isn’t a free upgrade.
We show phloem proteins can boost resistance to one attacker but increase susceptibility to another (incl. cyst nematodes).
Great collaboration 🙌
