Project description:affy_rice_2011_03 - affy_compartimentation_rice_albumen_embryon - During germination, the rice seed goes from a dry quiescent state to an active metabolism. As with all cereals, the rice seed is highly differentiated between the embryo (that will give rise to the future plantlet) and the endosperm (that contains the seed storage compounds and that will degenerate). The molecular mechanisms operating in the rice seed embryo have begun to be described. Yet, very few studies have focused specifically on the endosperm during the germination process. In particular, the endosperm is mostly addressed with regards to its storage proteins but we have detected a large protein diversity by two-dimensional electrophoresis. Similarly, the endosperm is rich in total RNA which suggest that gene expression coming from seed maturation could play a role during the germination process. In this context, we want to compare the transcriptome of the embryo and the endosperm during rice seed germination. -We germinate rice seeds of the first sequenced rice cultivar i.e. Nipponbare during 0, 4, 8, 12, 16 and 24h of imbibition in sterile distilled water. Germination occurs under constant air bubbling, in the dark at 30°C. These rice seeds are then manually dissected into embryo and endosperm fractions. -The embryo-derived samples are abbreviated in “E” while the endosperm samples are abbreviated “A”. The germination time-point is indicated after the letter (e.g. E8 for embryo samples harvested after 8 hours of germination). Finally, the biological repetition number is indicated before the letter and the time digit (e.g. 1-E8 for an embryo sample from the first repetition at 8 hours of imbibition).

Project description:RNA-seq performed on rice stem. The comparison is made to discover differentially expressed genes between Nipponbare wild-type unelongated stems (samples were taken 20 days after germination, when internodes are still compressed at the base of the plant) and pine1 knockout mutants, which show internode elongation even though floral induction didn't occur.

Project description:Low temperature is one of the major factors affecting rice germination, and low tempera-ture germination (LTG) is an important agronomic trait. Although genetic variation is abundant in rice germplasm resources, the molecular mechanism of LTG remains poorly understood. In this study, we first proved that weedy rice WR04-6 had significantly better low-temperature germination (LTG) ability at 10°C than the cultivated rice Qishanzhan (QSZ). RNA-seq was used to investigate the gene expression of WR04-6 and QSZ at 10, 12 and 14 days of seed germination at 10°C. The results of GO enrichment and KEGG en-richment revealed that the differentially expressed genes between WR04-6 and QSZ were mainly concentrated on the response to starch catabolic processes and the response to ab-scisic acid. This is consistent with the results of α-amylase activity, ABA and GA treat-ment. A recombinant inbred line (RIL) population derived from a cross between WR04-6 and QSZ and its high density SNP genetic map were used to detect quantitative trait loci (QTL) for low temperature germination rates at 10°C for 14 days. The results showed that two new QTLs were located on chromosome 3 and chromosome 12. Combined with the mapped QTLs and RNA-seq differential genes (DEGs), sixteen candidate genes potentially associated with LTG were identified. Validation of expression of the candidates by qRT-PCR were consistent with the RNA-seq data. These results will enable us to under-stand the genetic basis of LTG in weedy rice and provide new genetic resources for gener-ation of rice germplasm with LTG.

Project description:Rapid and uniform seed germination is required for modern cropping system. Thus, it is important to optimize germination performance through breeding strategies in maize, in which identification for key regulators is needed. Here, we characterized an AP2/ERF transcription factor, ZmEREB92, as a negative regulator of seed germination in maize. Enhanced germination in ereb92 mutants is contributed by elevated ethylene signaling and starch degradation. Consistently, an ethylene signaling gene ZmEIL7 and an α-amylase gene ZmAMYa2 are identified as direct targets repressed by ZmEREB92. OsERF74, the rice ortholog of ZmEREB92, shows conserved function in negatively regulating seed germination in rice. Importantly, this orthologous gene pair is likely experienced convergently selection during maize and rice domestication. Besides, mutation of ZmEREB92 and OsERF74 both lead to enhanced germination under cold condition, suggesting their regulation on seed germination might be coupled with temperature sensitivity. Collectively, our findings uncovered the ZmEREB92-mediated regulatory mechanism of seed germination in maize and provide breeding targets for maize and rice to optimize seed germination performance towards changing climates.

Project description:Sucrose non-fermenting-1-related protein kinase 1 (SnRK1) is a central regulator of metabolism and developmental transition in plant. Compound 991 is a well-known 5′-adenosine monophosphate activated protein kinase (AMPK) activator in mammals. SnRK1 and AMPK are highly conserved. However, whether 991 could also act as a SnRK1 activator is unknown. Adding 991 significantly increased the activity of SnRK1 in desalted extracts from germinating rice seeds in vitro. To determine whether 991 has biological activity in plant, rice seeds were treated with different concentrations of 991. Low concentration of 991 promoted rice seed germination, while high concentration of 991 inhibited rice germination. The effect of 991 on rice germination is similar to the effect of OsSnRK1a overexpression on germination. To explore whether 991 affects germination by specifically affecting SnRK1, the germination status of the snrk1a mutant and WT under 1 μM 991 treatment were compared. The snrk1a mutant exhibited insensitivity to 991. Through phosphoproteomic analysis, we found that the differential phosphopeptides caused by 991 treatments and overexpression of OsSnRK1a are largely overlapped. Phosphoproteomic analysis also revealed that SnRK1 might affect rice germination by regulating the phosphorylation levels of S285-PIP2;4, S1013-SOS1 and S110-ABI5. These results showed that 991 is a specific and workable SnRK1 activator in rice. The promotion and inhibition of 991 treatments on germination also exist in wheat seeds. 991 is expected to be used for exploring the function of SnRK1 in more detail and depth and chemical regulation of growth and development in crops.

Project description:Chloramphenicol (CAM) is recognized as one such factor that influence the seed germination. However, the mechanism by which CAM induced suppression on rice germination remains uncertain. To investigate the effect of CAM on rice seed germination, changes in the global profile of phosphorylated proteins induced by CAM were analyzed using LC-MS/MS.
