Evidence Snippets

We used loss-of-function mutants to study three Arabidopsis thaliana sensor histidine kinases, AHK2, AHK3, and CRE1/AHK4, known to be cytokinin receptors.

Linked Claims

Claim 1functional relationshipsupports2005Source 1DOIPubMed

The cytokinin receptors have partially redundant functions.

Quoted textsource-backed
Together, the analyses reveal partially redundant functions of the cytokinin receptors
Claim 2genetic inferencesupports2005Source 1DOIPubMed

Genetic analysis indicated a cytokinin-dependent endospermal and/or maternal control of embryo size.

Increased cytokinin content in receptor mutants indicates homeostatic control of steady-state cytokinin levels through signaling.

Claim 4molecular functionsupports2005Source 1DOIPubMed

AHK2, AHK3, and CRE1/AHK4 are cytokinin receptors.

Claim 5pathway dependencymixed2005Source 1DOIPubMed

Previously reported modulation of red light signaling by A-type response regulators may not depend on cytokinin.

Quoted textsource-backed
Unchanged red light sensitivity of mutant hypocotyl elongation suggests that previously reported modulation of red light signaling by A-type response regulators may not depend on cytokinin.
Claim 6phenotypic effectsupports2005Source 1DOIPubMed

Loss-of-function cytokinin receptor mutants show more rapid germination, reduced light requirement, and decreased far-red light sensitivity, indicating cytokinin functions in seed germination control.

Quoted textsource-backed
Mutant seeds had more rapid germination, reduced requirement for light, and decreased far-red light sensitivity, unraveling cytokinin functions in seed germination control.

Triple cytokinin receptor mutant seeds are more than twice as large as wild-type seeds.
