Claim 1expression responsesupports2025Source 1DOI PubMed

ZmLBD33 expression is strongly induced in roots under drought and ABA treatments.

Claim 2mechanistic conclusionsupports2025Source 1DOI PubMed

ZmLBD33 negatively regulates drought tolerance by modulating stomatal aperture and H2O2 signaling.

Claim 3molecular interaction propertysupports2025Source 1DOI PubMed

ZmLBD33 exhibits dimerization in a yeast two-hybrid assay despite lacking intact leucine zipper motifs.

Claim 4phenotypic effectsupports2025Source 1DOI PubMed

Overexpression of ZmLBD33 in transgenic Arabidopsis decreases drought tolerance under osmotic stress and soil drought relative to wild type.

Claim 5physiological mechanismsupports2025Source 1DOI PubMed

ZmLBD33 overexpression is associated with faster water loss, greater stomatal density, and reduced stomatal closure efficiency compared with wild type.

Claim 6redox responsesupports2025Source 1DOI PubMed

Transgenic Arabidopsis overexpressing ZmLBD33 shows attenuated reactive oxygen species accumulation and elevated SOD and POD levels relative to wild type.

Claim 7subcellular localizationsupports2025Source 1DOI PubMed

ZmLBD33 localizes to the nucleus.
