“…Two protein families, Aux/IAA and ARF, are known to mediate the auxin signaling molecule pathway [25]. With the development of genome sequencing, the Aux/IAA gene family has been reported in more than 30 plant species, including 29 genes from Arabidopsis thaliana , 17 from Medicago truncatula , 27 from Cucumis sativus , 26 from Solanum lycopersicum , 26 from V. vinifera, 35 from Populus trichocarpa and 26 from Citrus [47]. Especially in Arabidopsis , the functions of Aux/IAA genes are quite well understood [17].…”

Auxin plays a key role in different plant growth and development processes, including flower opening and development. The perception and signaling of auxin depend on the cooperative action of various components, among which auxin/indole-3-acetic acid (Aux/IAA) proteins play an imperative role. In a recent study, the entire Aux/IAA gene family was identified and comprehensively analyzed in Hedychium coronarium, a scented species used as an ornamental plant for cut flowers. Phylogenetic analysis showed that the Aux/IAA gene family in H. coronarium is slightly contracted compared to Arabidopsis, with low levels of non-canonical proteins. Sequence analysis of promoters showed numerous cis-regulatory elements related to various phytohormones. HcIAA genes showed distinct expression patterns in different tissues and flower developmental stages, and some HcIAA genes showed significant responses to auxin and ethylene, indicating that Aux/IAAs may play an important role in linking hormone signaling pathways. Based on the expression profiles, HcIAA2, HcIAA4, HcIAA6 and HcIAA12, were selected as candidate genes and HcIAA2 and HcIAA4 were screened for further characterization. Downregulation of HcIAA2 and HcIAA4 by virus-induced gene silencing in H. coronarium flowers modified the total volatile compound content, suggesting that HcIAA2 and HcIAA4 play important roles in H. coronarium floral scent formation. The results presented here will provide insights into the putative roles of HcIAA genes and will assist the elucidation of their precise roles during floral scent formation.

“…In addition, auxin serves as a cellular signal to control growth rate and other aspects of plant growth (Silvaci & Yacin 2008). Therefore, Gaudinova et al (2009) found that the amount of endogenous auxin also increased along the flower formation; however, it was not the same with cytokinin in blanka's plants.…”

Jatropha curcas (JC) is a crop with potential for use in biodiesel. Production of biodiesel requires plant seed as raw material, so the viability of JC for use in biodiesel will dependent greatly on the plant's production of flowers. Generally, this plant is monoecious, meaning it has both male and female flowers. However, very rarely JC plants may be andromonoecious. Andromonoecious specimens of JC produce hermaphrodite and male flowers in the same plant. The number of hermaphrodite flowers per inflorescence is generally low compared to the number of male flowers. The aim of this study was to increase the proportion of hermaphrodite flowers by using plant growth regulators (PGRs) in andromonoecious JC. Our experiment was conducted in Randomized Block Design (RBD) with 9 treatments, namely kinetin, GA 3 , and IAA with concentrations of 0 ppm as a control, 50 and 100 ppm of each PGRs. The treatments were applied to stem cuttings from each plant and repeated 4 times. PGRs were applied by spraying the leaves within the buds of each plant. Applications took place weekly beginning when the plants entered flower initiating phase, until inflorescence produced. Observations were conducted during the treatment period (10 weeks). Results showed that plants treated with IAA, GA 3 , and kinetin at 50 and 100 ppm produced increased inflorescence per plant. The increases measured were 155.4 and 92.9% of (IAA), 120.4 and 151% (GA 3 ), 96.6 and 51.7% (kinetin) respectively. In addition, we found that application and GA 3 at concentrations of 50 and 100 ppm, and kinetin at 50 ppm, increased the number of hermaphrodite flowers per inflorescence by 50%, and increased the number of hermaphrodite flowers per plant by 275.6 and 183.1% (IAA), 219.5 and 254.1% (GA 3 ), 162.9 and 103.1% (kinetin) respectively. As would be expected, the number of fruit per plant increased in those specimens treated with IAA, GA 3 , and kinetin at 50 and 100 ppm. The increases measured were 301.7 and 167.4% (IAA), 211.7 and 257.0% (GA 3 ), 162.5 and 101.4% (kinetin) respectively.
