MiR168 targets Argonaute1A mediated miRNAs regulation pathways in response to potassium deficiency stress in tomato.

ABSTRACT:

Background

Potassium (K⁺) is an essential ion for most plants, as it is involved in the regulation of growth and development. K⁺ homeostasis in plant cells has evolved to facilitate plant adaptation to K⁺-deficiency stress. Argonaute1 (AGO1) is regulated by miR168 to modulate the small RNA regulatory pathway by RNA silencing complex (RISC) in tomatoes. However, the role of miR168-mediated regulation of AGO1 in the context of K⁺ deficiency stress in tomatoes has not been elucidated yet.

Results

SlmiR168 and its target gene SlAGO1A were differentially expressed among low-K⁺-tolerant JZ34 and low-K⁺-sensitive JZ18 tomato plants. Transgenic tomato plants constitutively expressing pri-SlmiR168a showed stronger root
