Identification of the FBN gene family in tomato and functional analysis of SlFBN11 in the electron transport under low night temperature.

FBNs are lipid-associated proteins that play a critical role in plant growth and stress response. However, the mechanisms of how FBNs proteins participate in the low night temperature response in tomato still unclear. Here we conducted a comprehensive genome-wide analysis of the FBN gene family in Solanum lycopersicum.

Ubiquitin-mediated degradation of SlPsbS regulates low night temperature tolerance in tomatoes.

PsbS protein is essential for the rapid induction of non-photochemical quenching (NPQ) under low night temperatures (LNTs), but its stability is often affected by adverse environmental conditions. However, the regulatory mechanism for the stability of PsbS or chloroplast proteins remains to be fully characterized. We show that LNT decreases NPQ levels and SlPsbS protein abundance in tomato leaves.

Exogenous DA-6 Improves the Low Night Temperature Tolerance of Tomato Through Regulating Cytokinin.

Low night temperature (LNT) causes environmental stress and has a severe and negative impact on plant growth and productivity. Synthetic elicitors can regulate plant growth and induce defense mechanisms from this type of stress. Here, we evaluated the effect of the exogenous growth regulator diethyl aminoethyl hexanoate (DA-6) in tomato leaf response to LNT stress.
