Mutation of the K+ transporter SlHAK5 of tomato alters pistil morphology, ionome, metabolome and transcriptome in flowers

Physiologia Plantarum, Volume 176, Issue 6, November/December 2024.
Abstract K+ accumulation in plant tissues is a crucial factor for plant growth and development. The tomato high‐affinity K+ transporter SlHAK5 is essential for root K+ acquisition from low external concentrations. It is also involved in K+ accumulation in pollen and plant fertility as slhak5 KO plants show a low rate of pollen germination, impaired ...
