The diageotropica mutation and synthetic auxins differentially affect the expression of auxin-regulated genes in tomato.
Plant physiology (1995)
Show / hide abstract
Show / hide abstract
The effect of a tomato (Lycopersicon esculentum) mutation, diageotropica (dgt), on the accumulation of mRNA corresponding to tomato homologs of three auxin-regulated genes, LeAux, LeSAUR, and Lepar, was examined. The dgt mutation inhibited the induction of LeAux and LeSAUR mRNA accumulation by naphthalene acetic acid (NAA) but had no effect on NAA-induced Lepar mRNA accumulation. The effect of two synthetic auxins, NAA and 3,7-dichloro-8-quinoline carboxylic acid (quinclorac), on the accumulation of LeAux, LeSAUR, and Lepar mRNA was also examined. Quinclorac induced the expression of each of the auxin-regulated genes, confirming its proposed mode of herbicidal action as an auxin-type herbicide. Concentrations of quinclorac at least 100-fold higher than NAA were required to induce LeAux and LeSAUR mRNA accumulation to similar levels, whereas Lepar mRNA accumulation was induced by similar concentrations of NAA and quinclorac. Collectively, these data suggest the presence of two auxin-dependent signal transduction pathways: one that regulates LeSAUR and LeAux mRNA accumulation and is interrupted by the dgt mutation and a second that regulates Lepar mRNA accumulation and is not defective in dgt tomato hypocotyls. These two auxin-regulated signal transduction pathways can be further discriminated by the action of two synthetic auxins, NAA and quinclorac.

The diageotropica mutation alters auxin induction of a subset of the Aux/IAA gene family in tomato.
Plant molecular biology (2000)
Show / hide abstract
Show / hide abstract
The diageotropica (dgt) mutation has been proposed to affect either auxin perception or responsiveness in tomato plants. It has previously been demonstrated that the expression of one member of the Aux/IAA family of auxin-regulated genes is reduced in dgt plants. Here, we report the cloning of ten new members of the tomato Aux/IAA family by PCR amplification based on conserved protein domains. All of the gene family members except one (LelAA7) are expressed in etiolated tomato seedlings, although they demonstrate tissue specificity (e.g. increased expression in hypocotyls vs. roots) within the seedling. The wild-type auxin-response characteristics of the expression of these tomato LelAA genes are similar to those previously described for Aux/IAA family members in Arabidopsis. In dgt seedlings, auxin stimulation of gene expression was reduced in only a subset of LelAA genes (LelAA5, 8, 10, and 11), with the greatest reduction associated with those genes with the strongest wild-type response to auxin. The remaining LelAA genes tested exhibited essentially the same induction levels in response to the hormone in both dgt and wild-type hypocotyls. These results confirm that dgt plants can perceive auxin and suggest that a specific step in early auxin signal transduction is disrupted by the dgt mutation.

Genome-wide analysis of Aux/IAA gene family in Solanaceae species using tomato as a model.
Molecular genetics and genomics : MGG (2012)
Show / hide abstract
Show / hide abstract
Auxin plays key roles in a wide variety of plant activities, including embryo development, leaf formation, phototropism, fruit development and root initiation and development. Auxin/indoleacetic acid (Aux/IAA) genes, encoding short-lived nuclear proteins, are key regulators in the auxin transduction pathway. But how they work is still unknown. In order to conduct a systematic analysis of this gene family in Solanaceae species, a genome-wide search for the homologues of auxin response genes was carried out. Here, 26 and 27 non redundant AUX/IAAs were identified in tomato and potato, respectively. Using tomato as a model, a comprehensive overview of SlIAA gene family is presented, including the gene structures, phylogeny, chromosome locations, conserved motifs and cis-elements in promoter sequences. A phylogenetic tree generated from alignments of the predicted protein sequences of 31 OsIAAs, 29 AtIAAs, 31 ZmIAAs, and 26 SlIAAs revealed that these IAAs were clustered into three major groups and ten subgroups. Among them, seven subgroups were present in both monocot and dicot species, which indicated that the major functional diversification within the IAA family predated the monocot/dicot divergence. In contrast, group C and some other subgroups seemed to be species-specific. Quantitative real-time PCR (qRT-PCR) analysis showed that 19 of the 26 SlIAA genes could be detected in all tomato organs/tissues, however, seven of them were specifically expressed in some of tomato tissues. The transcript abundance of 17 SlIAA genes were increased within a few hours when the seedlings were treated with exogenous IAA. However, those of other six SlIAAs were decreased. The results of stress treatments showed that most SIIAA family genes responded to at least one of the three stress treatments, however, they exhibited diverse expression levels under different abiotic stress conditions in tomato seedlings. SlIAA20, SlIAA21 and SlIAA22 were not significantly influenced by stress treatments even though at least one stress-related cis-element was identified in their promoter regions. In conclusion, our comparative analysis provides an insight into the evolution and expression patterns in various tissues and in response to auxin or stresses of the Aux/IAA family members in tomato, which will provide a very useful reference for cloning and functional analysis of each member of AUX/IAA gene family in Solanaceae crops.

Genome-wide identification, functional analysis and expression profiling of the Aux/IAA gene family in tomato.
Plant & cell physiology (2012)

Show / hide abstract
Auxin is a central hormone that exerts pleiotropic effects on plant growth including the development of roots, shoots, flowers and fruit. The perception and signaling of the plant hormone auxin rely on the cooperative action of several components, among which auxin/indole-3-acetic acid (Aux/IAA) proteins play a pivotal role. In this study, we identified and comprehensively analyzed the entire Aux/IAA gene family in tomato (Solanum lycopersicum), a reference species for Solanaceae plants, and the model plant for fleshy fruit development. Functional characterization using a dedicated single cell system revealed that tomato Aux/IAA proteins function as active repressors of auxin-dependent gene transcription, with, however, different Aux/IAA members displaying varying levels of repression. Phylogenetic analysis indicated that the Aux/IAA gene family is slightly contracted in tomato compared with Arabidopsis, with a lower representation of non-canonical proteins. Sl-IAA genes display distinctive expression pattern in different tomato organs and tissues, and some of them display differential responses to auxin and ethylene, suggesting that Aux/IAAs may play a role in linking both hormone signaling pathways. The data presented here shed more light on Sl-IAA genes and provides new leads towards the elucidation of their function during plant development and in mediating hormone cross-talk.
