Two antagonistic gene regulatory networks drive Arabidopsis root hair growth at low temperature

This paper identifies two opposing gene regulatory networks that control root hair growth in Arabidopsis at low temperature, revealing their role in integrating environmental and internal signals.

NAC1 directs CEP1-CEP3 peptidase expression and modulates root hair growth in Arabidopsis

This study shows that NAC1 regulates AtCEP expression, which controls root hair growth by modulating EXT processing in Arabidopsis.

Arabidopsis pollen Prolyl-hydroxylases P4H4/6 are required for correct hydroxylation and secretion of LRX11 in pollen tubes

Pollen-expressed P4H4 and P4H6 are required for pollen germination and for proper hydroxylation and secretion of LRX11 in pollen tubes.

Apoplastic class III peroxidases PRX62 and PRX69 regulate ROS-homeostasis and cell wall associated extensins linked to root hair growth at low-temperature in Arabidopsis thaliana

The paper identifies PRX62 and PRX69 as apoplastic peroxidases that regulate ROS homeostasis and cell wall extensin insolubilization, affecting root hair growth at low temperatures in Arabidopsis thaliana.

Proline-rich Extensin-like Receptor Kinases PERK5 and PERK12 are involved in Pollen Tube Growth

This study identifies PERK5 and PERK12 as essential for pollen tube growth in Arabidopsis, showing defects in cell wall assembly and increased ROS levels in mutants.

The lncRNA APOLO interacts with the transcription factor WRKY42 to trigger root hair cell expansion in response to cold

The paper shows that the lncRNA APOLO interacts with WRKY42 to regulate RHD6 transcription, enhancing root hair elongation in response to cold.

CONFLICTING AUXIN-PHOSPHATE SIGNALS IMPACT ON RSL2 EXPRESSION AND ROS-HOMEOSTASIS LINKED TO ROOT HAIR GROWTH IN ARABIDOPSIS

The paper investigates how root hairs in Arabidopsis integrate conflicting signals from high phosphate and auxin levels to regulate RSL2 expression and ROS homeostasis affecting growth.
