FIGURE 5.

Proposed model for the function of LSM1-7 complex in plant response to abiotic stresses. Depending on the adverse environmental condition (i.e., low temperature, drought or high salinity), the LSM1-7 complex would target stress-specific transcripts encoding essential regulators of plant tolerance to the corresponding stress situation, promoting their decay and, thus, giving rise to an specific gene expression profile. Arrowheads and end lines indicate positive and negative regulation, respectively.
