Gene Details:

• Gene ID: Gh_A04G0109
• Gene Symbol: GhGLU19A
• Gene Name: Glucanase 19
• Genome: TM1_NBI
• Species: Gossypium hirsutum

Functional Descriptions:

• Suppression of GhGLU19 encoding β-1,3-glucanase promotes seed germination in cotton.
• GhGLU19 belongs to subfamily B and was expressed predominately in imbibed seeds and early seedlings. Compared to wild type, GhGLU19-suppressing and GhGLU19-overexpressing transgenic cotton lines showed the higher and lower seed germination percentage, respectively.
• Callose was enriched more at inner integument (ii) than that in embryo and seed coat in cotton seeds. In GhGLU19-suppressing lines, callose at ii of cotton seeds was greatly increased and brought about a prolonged water uptake process during imbibition.
• Both proteomic and transcriptomic analysis revealed that contrary to GhGLU19-overexpressing lines, the glycolysis and pyruvate metabolism was decreased, and abscisic acid (ABA) biosynthesis related genes were downregulated in imbibed seeds of GhGLU19-suppressing lines.
• Endogenous ABA was significantly decreased in GhGLU19-suppressing line while increased in GhGLU19-overexpressing line.
