Gene regulation in parthenocarpic tomato fruit

ABSTRACT: To evaluate the role of seeds in fruit quality, we induced parthenocarpy in tomato by regulating ovule-specific auxin synthesis or responsiveness using the INO promoter from A. thaliana, which is expressed in the outer layer of the integuments during early stages of ovule development. We compared these to fruit where the same coding regions were expressed from the DeFH9 promoter which is expressed in carpel tissues during early stages of ovule development. Expression of auxin synthesis or responsiveness genes by both of these promoters produced seedless parthenocarpic tomato fruit. We compared fruit samples using the Affymetrix tomato GeneChip (GPL4741) to determine how gene regulation and expression differed between wild-type and transgenic fruit.

Experiment Overall Design: Wild-type fruit with seeds was compared with transgenic lines INO-IaaM, DefH9-IaaM, INO-RolB, and DefH9-RolB. To find genes with seed-specific expression, we also compared the control with wild-type fruit from which seeds had been manually removed. We had three biological replicates for each treatment and control except DefH9-RolB, for which only two replicates were available. Each CEL file from the microarray represents one plant from each line.

The search of genetic resources for parthenocarpic pears and comparison of gene expression between high and low parthenocarpy cultivars

Project description:Parthenocarpy—the production of seedless fruits without fertilization—is very useful for fruit cultivation. Among pear cultivars (Japanese, Chinese, and European pears and their interspecific hybrids) subjected to flower emasculation and left unpollinated, only some of the European pears had a stable and high degree of fruit set and fruit enlargement. Almost all the enlarged fruits formed no seeds. Comparison of fruits produced by using emasculation without pollination or with self-pollination ruled out the possibility of stenospermocarpy in these parthenocarpic pears. The results suggested that the abovementioned characteristics were inherited maternally by the next generation and that it should be possible to introduce parthenocarpy into Japanese pears. Neither Chinese nor Japanese pears treated with emasculation and no pollination showed consistently stable fruit set or fruit enlargement. In Chinese pears, these characteristics varied greatly from year to year, and in Japanese pears they were stable but weak. Although in each cultivar highly parthenocarpic fruits weighed slightly less than cross-pollinated ones, the cortexes of the emasculated fruits were enlarged and the fruits were not greatly inferior to those of cross-pollinated ones. By using a customized pear cDNA microarray, we compared the gene expression profiles of highly and weakly parthenocarpic cultivars before flowering. Expression of several phenylpropanoid-related genes and photosystem-related genes differed significantly between the two groups. Some of these genes were contained in the chloroplast genome. These results showed the unique mechanism of genetic parthenocarpy in pome fruits as opposed to non-pome fruits. The gene expression profiles between high and low parthenocarpy group before flowering were compared.

Transcription profiling of pistils from Arabidopsis wild type, ant-4 mutant and ino-1mutant plants at different developmental stages

Project description:This experiment was designed to identify genes expressed preferentially in the two integuments of the Arabidopsis ovule. Pistils from wild type and two ovule mutants were compared against each aintegumenta-4 (ant-4) which lacks both integuments and inner no outer (ino-1) which lacks the outer integument. Genes that are highly expressed only in the integuments were expected to be reduced in expression in the mutants, as compared with wild type. Pistils containing ovules through all stages of ovule development prior to pollination were pooled for one experiment (FULL arrays), and for two separate experiments, a set of early differentiation stages (EARLY arrays) and a set of later differentiation stages (LATE ARRAYS) were pooled. Wild type and mutant lines are in the ecotype Landsberg erecta.

MicroRNAs Associated with AGL6 and IAA9 function in tomato fruit set

Project description:Fruit set is triggered after ovule fertilization, as a consequence of the downregulation of ovary growth repressors, such as the tomato transcription factors Auxin/indole-3-acetic acid 9 (IAA9) and Agamous-like 6 (AGL6). We produced small RNA libraries from IAA9- and AGL6-silenced ovaries to identify miRNAs differentially expressed in IAA9- and AGL6-silenced ovaries as compared with unpollinated control ovaries. The identified miRNAs represent a pool of regulatory sRNAs potentially involved in tomato fruit initiation.

Spatial-temporal order of regulation in tomato early fruit development

Project description:Early fruit development is crucial for crop production in tomato. After fertilization, the ovary undergoes a cell division and a cell expansion stages before maturation. Although the roles of regulatory signals such as hormone and carbohydrate during early fruit development have been studied, the spatial distribution and the sequential initiation of these regulatory signals is still poorly understood. Using the cultivated tomato “Moneymaker” as materials, we analyzed the transcriptome of the ovule and the ovary wall dissected from the different stages of the early developing fruits. These datasets provide us the whole picture about the spatial and temporal signal distribution of fruit formation which has not been studied in such a detailed manner. Our results suggest that the hormone signal was initiated in both ovule and ovary wall after fertilization. After that, the different signals were activated in ovule and ovary wall due to their distinct developmental processes. By analyzing the global expression profiling of hormone related genes, we found that the auxin might be synthesized in both ovule and ovary wall after fertilization. The expression pattern of sugar related genes revealed the different carbohydrate metabolism events occurred in ovule and ovary wall. At last, we identified a gene showed tissue and stage specific expression pattern and localized in previously reported fruit weight locus which might be selected during tomato breeding.

Transcriptome data from tomato parthenocarpic mutants lacking Tomato APETALA3 (TAP3)

Project description:We investigated the behavior of tomato mutants lacking transcription factors of TAP3, a class B MADS-box gene controlling parthenocarpy. To focus on the early stages of anthesis, ovary samples of MicroTom-J (MT-J) and the mutant at the different stages (e.g., bud, flowering, and after flowering) were collected.
