Unstructured regions differentially modulate the activation of RBOHD and RBOHH

The paper identifies unstructured regions in RBOHs that differentially regulate their activation in immune signaling and pollen tube growth.

A plasmodesmata-specific exocyst complex regulates symplastic connectivity by affecting callose turnover

Loss of PR1 function enhances Arabidopsis resistance to Botrytis cinerea

This study shows that loss of PR1 function in Arabidopsis enhances resistance to Botrytis cinerea but increases susceptibility to Pseudomonas syringae.

Evolutionary analysis of the exocyst in streptophytes links EXO70 diversification to dominance over SEC3 in membrane targeting

This study traces the evolutionary diversification of EXO70 in streptophytes, showing its origin in the common ancestor of land plants and its functional specialization in membrane targeting.

Independent roles of Arp2/3 complex and RIC4 protein in the control of epidermal cell shape

This study shows RIC4 and Arp2/3 complex independently regulate Arabidopsis cotyledon epidermal cell shape without shared signaling pathways.

Sequence and structural rules define PY-NLS-dependent nuclear import by TRANSPORTIN 1 in plants

The paper identifies a plant-specific PY-NLS pathway mediated by TRN1, revealing structural features distinguishing plant PY-NLSs from animal and fungal models.
