Solanum lycopersicum AUXIN RESPONSE FACTOR 9 regulates cell division activity during early tomato fruit development
The transformation of the ovary into a fruit after successful completion of pollination and fertilization has been associated with many changes at transcriptomic level. These changes are part of a dynamic and complex regulatory network that is controlled by phytohormones, with a major role for auxin. One of the auxin-related genes differentially expressed upon fruit set and early fruit developm...
متن کاملThe Solanum lycopersicum AUXIN RESPONSE FACTOR 7 (SlARF7) mediates cross-talk between auxin and gibberellin signalling during tomato fruit set and development
Transgenic tomato plants (Solanum lycopersicum L.) with reduced mRNA levels of AUXIN RESPONSE FACTOR 7 (SlARF7) form parthenocarpic fruits with morphological characteristics that seem to be the result of both increased auxin and gibberellin (GA) responses during fruit growth. This paper presents a more detailed analysis of these transgenic lines. Gene expression analysis of auxin-responsive gen...
متن کاملRoot-synthesized cytokinins improve shoot growth and fruit yield in salinized tomato (Solanum lycopersicum L.) plants
Salinity limits crop productivity, in part by decreasing shoot concentrations of the growth-promoting and senescence-delaying hormones cytokinins. Since constitutive cytokinin overproduction may have pleiotropic effects on plant development, two approaches assessed whether specific root-localized transgenic IPT (a key enzyme for cytokinin biosynthesis) gene expression could substantially improv...
متن کاملGenome-wide identification of pistil-specific genes expressed during fruit set initiation in tomato (Solanum lycopersicum)
Fruit set involves the developmental transition of an unfertilized quiescent ovary in the pistil into a fruit. While fruit set is known to involve the activation of signals (including various plant hormones) in the ovary, many biological aspects of this process remain elusive. To further expand our understanding of this process, we identified genes that are specifically expressed in tomato (Sol...
متن کاملSalinity Stress Affects Assimilate Metabolism at the Gene-expression Level during Fruit Development and Improves Fruit Quality in Tomato (Solanum lycopersicum L.)
Irrigation with moderate salinity stress in a hydroponic system improves the inner and outer fruit quality of tomato (Solanum lycopersicon Mill. ‘House Momotaro’). We investigated the effects of 50 mM NaCl in a hydroponic solution on the levels of various metabolites, including soluble sugars, amino acids, and organic acids, and on the expression levels of salinity-responsive genes during fruit...
