Exogenous putrescine increases the responsiveness of thermodormant Avena fatua L. caryopses to karrikinolide and gibberellic acid

A natural feature of freshly harvested Avena fatua L. caryopses is primary dormancy which, however, was relieved partially by putrescine (Put) (10−2 M) and completely by karrikinolide (KAR1) (3 × 10−9 M) or gibberellic acid (GA3) (10−5 M). The sensitivity of A. fatua caryopses to these stimulators was adversely affected by supraoptimal temperature (SOT) (30 °C). A reduced ...

Regulation of ethylene biosynthesis at the level of 1-aminocyclopropane-1-carboxylate oxidase (ACO) gene

Ethylene, a gaseous plant hormone regulates essentially all physiological processes during the plant’s life cycle. The practical implications of ethylene biosynthesis regulation for plant improvement have supported the continuous basic research on dissecting the structure of genes encoding ethylene biosynthetic enzymes, their differential expression patterns, and mechanisms ...
