Susceptibility to Zika virus in a Collaborative Cross mouse strain is induced by Irf3 deficiency in vitro but requires other variants in vivo, not linked to the type I interferon response.

This study identifies an Irf3 mutation causing defective type-I interferon response in vitro in a susceptible mouse strain but shows other genetic factors are required for in vivo susceptibility to ZIKV.

Pectin cell wall remodeling through PLL12 and callose deposition through polar CALS7 are necessary for long-distance phloem transport

This study identifies PLL12 and CALS7 as essential for phloem transport by remodeling pectin and callose in sieve pores, affecting long-distance symplastic transport.

An Arabidopsis root phloem pole cell atlas reveals PINEAPPLE genes as transitioners to autotrophy

The paper generates a single-cell atlas of Arabidopsis root phloem pole cells and identifies PINEAPPLE genes as key regulators in the transition to autotrophy.

Formation of flavone-based wooly fibres by glandular trichomes of Dionysia tapetodes.

The paper investigates the formation of wooly fibres in Dionysia tapetodes, showing they are composed of flavone derivatives and extruded through specific cell membrane sites.

Structural imaging of native cryo-preserved secondary cell walls reveals presence of macrofibrils composed of cellulose, lignin and xylan.

This study uses cryo-SEM to image native secondary cell walls, revealing macrofibrils composed of cellulose, xylan, and lignin in both angiosperm and gymnosperm species.

ELIMAKI locus is required for mechanosensing and proprioception in birch trees

The study identifies a mutant birch tree (Elimaki) with impaired proprioception and radial growth, linking mechanical stress response to cell wall properties and transcriptomic changes.
