AtFTCD-L, a trans-Golgi network localized protein, modulates root growth of Arabidopsis in high-concentration agar culture medium.

AtFTCD-L protein is localized on the TGN vesicles in Arabidopsis root cap cells. AtFTCD-L mutation resulted in slow root growth of Arabidopsis in high-concentration agar culture medium. Arabidopsis formiminotransferase cyclodeaminase-like protein (AtFTCD-L) in Arabidopsis is homologous to the formiminotransferase cyclodeaminase (FTCD) protein in animal cells.

Mechanisms used by DNA MMR system to cope with Cadmium-induced DNA damage in plants.

Cadmium (Cd) is found widely in soil and is severely toxic for plants, causing oxidative damage in plant cells because of its heavy metal characteristics. The DNA damage response (DDR) is triggered in plants to cope with the Cd stress. The DNA mismatch repair (MMR) system known for its mismatch repair function determines DDR, as mispairs are easily generated by a translesional synthesis under Cd-induced genomic instability.

Arabidopsis PCaP2 Functions as a Linker Between ABA and SA Signals in Plant Water Deficit Tolerance.

Water stress has a major influence on plant growth, development, and productivity. However, the cross-talk networks involved in drought tolerance are not well understood. Arabidopsis PCaP2 is a plasma membrane-associated Ca-binding protein.

Arabidopsis PCaP2 Plays an Important Role in Chilling Tolerance and ABA Response by Activating CBF- and SnRK2-Mediated Transcriptional Regulatory Network.

Chilling stress affects plant growth and productivity. However, the multi-underlying mechanisms of chilling tolerance are not well understood. Arabidopsis PCaP2 is involved in regulating the dynamic of microtubules (MTs) and F-actin and Ca-binding ability.
