“…GA has been shown to affect immediate increases in photosynthetic rates in toma toes (Coulombe and Paquin, 1959), corn, beans and clover {Trifoiium pratense) (Treharne and Stoddart, 1968). Numerous other plants (Marth et al, 1956;Gray, 1957;Coleman, 1958;and Peterson, 1958) have shown dry weight increased from GA.…”

“…GAs are endogenous plant hormones that influence several aspects of plant growth and development, including seed germination, leaf expansion, shoot growth, cell division, flower induction, and fruit development (Sun and Gubler, 2004;Fleet and Sun, 2005;Swain and Singh, 2005). With respect to shoot growth, the most obvious effect of GA is its promotion of stem elongation by stimulating both cell elongation and division (Marth et al, 1956). GA modification also has significant effects on plant biochemistry, changing the amounts and distribution of a wide variety of metabolites in shoots and roots (Rossetto et al, 2003;Chen et al, 2004;Busov et al, 2006).…”

Green Revolution Trees: Semidwarfism Transgenes Modify Gibberellins, Promote Root Growth, Enhance Morphological Diversity, and Reduce Competitiveness in Hybrid Poplar

et al. 2012

Semidwarfism has been used extensively in row crops and horticulture to promote yield, reduce lodging, and improve harvest index, and it might have similar benefits for trees for short-rotation forestry or energy plantations, reclamation, phytoremediation, or other applications. We studied the effects of the dominant semidwarfism transgenes GA Insensitive (GAI) and Repressor of GAI-Like, which affect gibberellin (GA) action, and the GA catabolic gene, GA 2-oxidase, in nursery beds and in 2-year-old high-density stands of hybrid poplar (Populus tremula 3 Populus alba). Twenty-nine traits were analyzed, including measures of growth, morphology, and physiology. Endogenous GA levels were modified in most transgenic events; GA 20 and GA 8 , in particular, had strong inverse associations with tree height. Nearly all measured traits varied significantly among genotypes, and several traits interacted with planting density, including aboveground biomass, rootshoot ratio, root fraction, branch angle, and crown depth. Semidwarfism promoted biomass allocation to roots over shoots and substantially increased rooting efficiency with most genes tested. The increased root proportion and increased leaf chlorophyll levels were associated with changes in leaf carbon isotope discrimination, indicating altered water use efficiency. Semidwarf trees had dramatically reduced growth when in direct competition with wild-type trees, supporting the hypothesis that semidwarfism genes could be effective tools to mitigate the spread of exotic, hybrid, and transgenic plants in wild and feral populations.
