SlECA4, an epsin-like clathrin adaptor protein, improves tomato heat tolerance via clathrin-mediated endocytosis.

Clathrin-mediated endocytosis (CME) is one of the main pathways for plant cells to internalize membrane proteins in response to changing environmental conditions. The Epsin-like Clathrin Adaptor (ECA) proteins play important roles in the assembly of the clathrin coat; however, their involvement in plant responses to heat stress remains unclear. Here we report that in tomato (Solanum lycopersicum), Epsin-like Clathrin Adaptor 4 (SlECA4) expression responded to heat stress.

Vesicle formation-related protein CaSec16 and its ankyrin protein partner CaANK2B jointly enhance salt tolerance in pepper.

Vesicle transport plays important roles in plant tolerance against abiotic stresses. However, the contribution of a vesicle formation related protein CaSec16 (COPII coat assembly protein Sec16-like) in pepper tolerance to salt stress remains unclear. In this study, we report that the expression of CaSec16 was upregulated by salt stress.
