Water as a Compass: Hydrostimulation-Triggered Aerial Root Growth in Phalaenopsis aphrodite
Epiphytic orchids have evolved specialized adaptive strategies, such as aerial roots with water- absorbing velamen tissues, to cope with water- scarce and nutrient- deficient habitats. Our previous study revealed that the aerial roots of the epiphytic orchid Phalaenopsis aphrodite lack a gravitropic response,
A chloroplast sulphate transporter modulates glutathione-mediated redox cycling to regulate cell division
Glutathione redox cycling is important for cell cycle regulation, but its mechanisms are not well understood. We previously identified a small-sized mutant, suppressor of mat3 15-1 (smt15-1) that has elevated cellular glutathione.
Diverse geotropic responses in the orchid family
In epiphytes, aerial roots are important to combat water‐deficient, nutrient‐poor, and high‐irradiance microhabitats. However, whether aerial roots can respond to gravity and whether auxin plays a role in regulating aerial root development remain open‐ended questions.
