Webthat the procera mutation does not directly affect either the GA status of the plant, or its ability to respond to GA. Key words: Extension growth - Gibberellin in tomato mutant - Lycopersicon (GA in mutant) - Mutant (tomato). Introduction Dwarf mutants have played an important part in the study of gibberellin (GA) interconversions in WebFurther, we demonstrate that fruit shape and pericarp layer number phenotypes of the 35S:amiR-TKN-II fruits can be overridden by the procera mutant, known to induce a constitutive response to the ...
WebIncreased levels or responses of the plant hormone gibberellin (GA) in tomato leaves also led to a simplified leaf form. Here, we show that LA activity is mediated in part by GA. Expression of the SlGA20 oxidase1 (SlGA20ox1) gene, which encodes an enzyme in the GA biosynthesis pathway, is increased in gain-of-function La mutants and reduced in ... WebJan 4, 2002 · The tomato (Solanum lycopersicum L.) slender mutant procera (pro) was analysed for its relationship with gibberellin (GA) by combining it with GA deficiency due …

Planta 172: 280-284 WebSeparately, it is well-documented that phytochromes (phys), gibberellin (GA) and abscisic acid (ABA) strongly control the seed germination in tomato. However, we hipothesized that phys interact with GA or ABA during this response. Thus, we make an analysis of seed germination of ABA deficient (sit), GA constitutive response (pro), phytochrome deficient …
