Motor Protein Myosin XI Found to Play Crucial Role in Plants' Active Boron Uptake

Motor protein myosin XI found to play crucial role in plants' active boron uptake

Boron, though required only in minimal amounts, is vital for plant development. It strengthens cell walls and supports the growth of roots and shoots. Normally, boron, in the form of boric acid, is passively absorbed by plant roots and transported throughout the plant via diffusion. However, boron is often scarce in soil, particularly in arid regions, making passive absorption impossible. To combat this, plants have evolved proteins that activel…

New study shows motor protein myosin XI is crucial for active boron uptake in plants - ChiniMandi

A new study from Waseda University reveals that the motor protein myosin XI is essential for helping plants absorb boron under nutrient-deficient conditions. Researchers found that myosin XI maintains the correct positioning of the boric acid channel AtNIP5;1 in root cells by supporting endocytosis. Without myosin XI, plants fail to localize this channel properly, leading to poor boron uptake and stunted growth. The findings could inform strateg…

Myosin XI Motor Protein Essential for Active Boron Uptake in Plants

In the intricate world of plant physiology, the uptake of essential micronutrients is fundamental to growth, development, and survival, especially under challenging environmental conditions. Among these nutrients, boron—a trace element required in minuscule quantities—plays a pivotal role. It contributes critically to the structural integrity of plant cell walls and supports the elongation and differentiation of roots and shoots. Conventionally,…
