Project description:In order to elucidate the molecular mechanism of gibberellin (GA)-induced mesocotyl elongation, gene expression profiling analyses were performed in a deep-sowing tolerant maize inbred line 3681-4. Gene expression studies combing Affymetrix GeneChip analysis and Real-time PCR were employed to determine the molecular mechanism underlying GA promotion of maize mesocotyl elongation. These studies showed that the GA receptor GID1, the transcriptional factor MYB, and the genes encoding DELLA protein DWRF8, kinases, Raf, LRR, RLCK, and involved in flavonoid biosynthesis, aminosugars metabolism, cell wall synthesis and modification, might play critical roles in maize mesocotyl elongation.

Project description:The time between seed germination and the development of the first true leaves is crucial for plants success. Depending on the environmental light conditions a plant must decide which developmental program to use. If light is limited, the seedling will use etiolated growth characterized by an elongated hypocotyl and tightly-closed, underdeveloped cotyledons, thus allowing it to reach a light source as quickly as possible. In contrast, seedlings that are grown in unlimited light will use de-etiolation growth, that is characterized by inhibited hypocotyl growth and unhooked, unfolded and fully expanded cotyledons. These seedlings become photosynthetic and increase their chances for reproduction. Interestingly, the outcome of the light signal varies between the seedling’s different organs, e.g. hypocotyl growth is inhibited by light whereas cotyledon expansion is induced. Separating the cotyledons and hypocotyls of de-etiolated seedlings during their first 12 hours of white light exposure, enabled us to perform individual transcriptome analyses of each organ and to examine what causes this variation in light responsiveness.

In two independent experiments, we generate 10-day-old maize mesocotyl-specific gene expression profiles through comparing genome-wide expression patterns of GA3 treatment and UCZ (a GA biosynthesis inhibitor) treatment under 20 cm deep-sowing condition in darkness by using 17,555 Affymetrix maize whole genome array.

Project description:Among multiple factors, light plays a decisive role in the switch from heterotrophic to autotrophic growth. Under dark condition, the rapeseed hypocotyl extended quickly with an apical hook, yellow and folded cotyledon, and the glyoxysome assembling. Whereas under light, the hypocotyl extended slowly, the cotyledon unfolded and turned green. In this study, we performed proteome profiling analyses to show the differential molecular responses of Brassica napus cotyledons to light and dark and reveal metabolic adaptations in postgerminative seedling establishment. In both light and dark-grown conditions.

Project description:Background The soybean (Glycine max) cotyledon is a specialized tissue whose main function is to serve as a nutrient reserve that supplies the needs of the young plant throughout seedling development. During this process the cotyledons experience a functional transition to a mainly photosynthetic tissue. To identify at the genetic level the specific active elements that participate in the natural transition of the cotyledon from storage to photosynthetic activity, we studied the transcript abundance profile at different time points using a new soybean oligonucleotide chip containing 19,200 probes (70-mer long). Results After normalization and statistical analysis we determined that 3,594 genes presented a statistically significant altered expression in relation to the imbibed seed in at least one of the time points defined for the study. Detailed analysis of this data identified individual, specific elements of the glyoxylate pathway that play a fundamental role during the functional transition of the cotyledon from nutrient storage to photosynthesis. The dynamics between glyoxysomes and peroxisomes is evident during these series of events. We also identified several other genes whose products could participate co-ordinately throughout the functional transition and the associated mechanisms of control and regulation and we described multiple unknown genetic elements that by association have the potential to make a major contribution to this biological process. Conclusions We demonstrate that the global transcript profile of the soybean cotyledon during seedling development is extremely active, highly regulated and dynamic. We defined the expression profiles of individual gene family members, enzymatic isoforms and protein subunits and classified them accordingly to their involvement in different functional activities relevant to seedling development and the cotyledonary functional transition in soybean, especially the ones associated with the glyoxylate cycle. Our data suggests that in the soybean cotyledon a very complex and synchronized system of control and regulation of several metabolic pathways is essential to carry out the necessary functions during this developmental process.

Project description:The analysis of gene expression during wheat development:; Gene expression measurements were carried out on a developmental tissue; series for wild-type wheat (cv. Chinese Spring) using the Affymetrix; Wheat GeneChip. Thirteen tissues at defined developmental stages were; chosen to match the barley (cv. Morex) tissue series of Druka et al. 2006 that used the Affymetrix Barley1 GeneChip. Three replicates of:; root tissue at two different developmental stages, leaf, crown,; caryopsis, anther, pistil, inflorescence, bracts, mesocotyl, endosperm,; embryo and coleoptiles were hybridised. Comparisons between this wheat; data and the barley dataset were performed and are available at; http://contigcomp.acpfg.com.au ; [PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Tim Sutton.

Project description:In order to elucidate the molecular mechanism of auxin-induced mesocotyl elongation, gene expression profiling analyses were performed in a deep-sowing tolerant maize inbred line 3681-4. Gene expression studies combing Affymetrix GeneChip analysis and Real-time PCR were employed to determine the molecular mechanism underlying IAA promotion of maize mesocotyl elongation. Under deep-sowing condition, IAA is transported by auxin transporter-like protein 1 and binds to auxin binding protein ABP20, which results in degradation of Aux/IAA and de-repressing of auxin-inducible genes. Then, transcriptional factor such as MYB, kinase such as LRR, fructose and mannose metabolism and so on are activated. Finally, genes involved in cell wall synthesis and modification are expressed so that mesocotyl elongation of 3681-4 is promoted. Furthermore, gene expression of a key enzyme ACO in ethylene biosynthesis and ethylene receptor ETR2 were up-regulated after the treatment with 10-4 M IAA, which suggested that mesocotyl elongation of 3681-4 inclined to be inhibited when the concentration of applied IAA was increased from 10-4 M to 10-3 M. In two independent experiments, we generate 10-day-old maize mesocotyl-specific gene expression profiles through comparing genome-wide expression patterns of IAA treatment and TIBA (an auxin transportation inhibitor) treatment under 20 cm deep-sowing condition in darkness by using 17,555 Affymetrix maize whole genome array.
