and held until further analysis. Identification of gibberellin metabolism and cell expansion-related genes. Tomato genes potentially associated with the regulation of later stages of GA metabolism ( GA20ox , GA3ox , and GA2ox ), GA signaling ( DELLA

, inactivation of bioactive gibberellins GA1 and GA4 is ensured by GA2-oxidases (GA2ox) that catalyze their 2β-hydroxylation yielding GA8 and GA34 ( Hedden and Proebsting, 1999 ). Overexpression of OsGA2ox1 in rice caused a dwarf phenotype with leaves that were

(GA20ox), GA 3-oxidase (GA3ox), and GA 2-oxidase (GA2ox). Arabidopsis has almost twice the number of enzymes for each family compared with papaya. GA20ox and GA3ox are involved in forming bioactive GAs, whereas GA2ox functions to deactivate bioactive

endodormant buds include gibberellin 2 oxidase (GA2ox; Table 1 ). Several reports have suggested critical roles of gibberellins (GAs), which promote progression from dormancy release, in acting downstream of environmental signals to regulate bud dormancy

from the normal strains. The dioxygenases GA-20ox, GA-3ox, and GA-2ox are often encoded by multigene families ( Sponsel and Hedden, 2010 ), so defects of certain enzymes in dwarf plants may be covered by other gene family members, which may have

suppression however elevation of catabolism (feedforward regulation) results from improved expression of the GA catabolic genes GA2ox. Exogenous application of GAs boosts the upregulation of GA20ox genes and CPS, and supports downregulation of GA3ox genes
