Ever wondered how the #cuticle, a hallmark of land plants, was established?

In our latest study, we show that the CUTIN SYNTHASE enzyme family was a key driver of this evolutionary innovation. #plantscience

The endocuticle structural glycoprotein AgSgAbd‐2‐like is required for cuticle formation and survival in the melon aphid Aphis gossypii The SgAbd proteins, which are regulated by the ecdysone signaling that enables subsequent metamorphosis, are required for endocuticle formation in the melon aphid. The reduction of SgAbd leads to let...

Dual roles of LmCDA1 and LmCDA2 in the assembly and integrity of the embryonic cuticle in Locusta migratoria In Locusta migratoria embryos, RNAi-mediated knockdown of LmCDA1 or LmCDA2 disrupts pro-nymphal cuticle formation. While LmCDA1 silencing reduces cuticle thickness without altering chitin lamellar or...

A thinner jacket for frosty and windy climates? Global patterns in leaf cuticle thickness and its environmental associations Plant cuticles protect the interior tissues from ambient hazards, including desiccation, UV light, physical wear, herbivores and pathogens. Consequently, cuticle properties are shaped by evolutionar...

Ep167: Origin of Teeth Pt2

There's something fishy about the teeth of the earliest vertebrates in the fossil record. An absolute rollercoaster of an episode with Dr Yara Haridy.

#aECM (apical extracellular matrix) is a subset of #ECMatrix that is distinct from stromal matrices or basement membranes. Anybody out there studying #mucins #ZPproteins #cuticle #glycocalyx #surfactant or the like? We need to find each other and start talking!

[Please repost] We propose a PhD project addressing the role of #ABA in #plant #adaptation to land via #cuticle plasticity control: vu.fr/OehUy

The project is open for competition in the frame of the Strasbourg ED414 graduate school: ed.vie-sante.unistra.fr/en/
