HAK/KUP/KT family potassium transporter genes are involved in potassium deficiency and stress responses in tea plants (Camellia sinensis L.): expression and functional analysis.

ABSTRACT:

Background

Tea plant is one of the most important non-alcoholic beverage crops worldwide. While potassium (K⁺) is an essential macronutrient and greatly affects the growth and development of plants, the molecular mechanism underlying K⁺ uptake and transport in tea plant root, especially under limited-K⁺ conditions, is still poorly understood. In plants, HAK/KUP/KT family members play a crucial role in K⁺ acquisition and translocation, growth and development, and response to stresses. Nevertheless, the biological functions of these genes in tea plant are still in mystery, especially their roles in K⁺ uptake and stress responses.

Results

In this study, a total of 21 non-redundant HAK/KUP/KT genes (designated as CsHAKs) wer
