<h4>Background</h4>The embryo sac contains the haploid maternal cell types necessary for double fertilization and subsequent seed development in plants. Large-scale identification of genes expressed in the embryo sac remains cumbersome because of its inherent microscopic and inaccessible nature. We used genetic subtraction and comparative profiling by microarray between the Arabidopsis thaliana wild-type and a sporophytic mutant lacking an embryo sac in order to identify embryo sac expressed gen ...[more]

Quantitative Proteomic Analysis of ER Stress Response Reveals both Common and Specific Features in Two Contrasting Ecotypes of Arabidopsis

Project description:Accumulation of unfolded/misfolded proteins in endoplasmic reticulum (ER) elicits a well conserved response called the Unfolded Protein Response (UPR), which triggers the up-regulation of downstream genes involved in protein folding, vesicle trafficking, and ER-Associated Degradation (ERAD). Although the dynamic transcriptomic responses and underlying major transcriptional regulators in ER stress response in plants have been well established, the proteome changes induced by ER stress have not been reported in plants. In the current study, we found that the Arabidopsis Ler ecotype is more sensitive to ER stress than the Col ecotype. Quantitative mass spectrometry analysis with Tandem Mass Tag (TMT) isobaric labeling showed that totally 7439 and 7035 proteins were identified from Col and Ler seedlings, with 88 and 113 differentially regulated (FC>1.3 or <0.7, P<0.05) proteins by ER stress in Col and Ler, respectively. Among them, 40 proteins were commonly up-regulated in Col and Ler, of which 10 were not up-regulated in bzip28 bzip60 double mutant (Col background) plants. Of the 19 specifically up-regulated proteins in Col comparing to that in Ler, components in ERAD, N-glycosylation, vesicle trafficking and molecular chaperones were represented. Quantitative RT-PCR showed that genes encoding 7 out of 19 proteins were not up-regulated (FC>1.3 or <0.7, P<0.05) by ER stress in both ecotypes while genes encoding 12 out of 19 proteins were up-regulated by ER stress with no obvious differences in fold change between Col and Ler. Our results experimentally demonstrated the robust ER stress response at proteome level in plants and revealed differentially regulated proteins that may contribute to differed ER stress sensitivity between Col and Ler ecotypes in Arabidopsis.

Exploring the selectivity and engineering potential of an NRPS condensation domain involved in the biosynthesis of the thermophilic siderophore fuscachelin

Project description:Condensation (C) domains are the key component linking different monomers together, typically forming peptide bonds and occasionally ester bonds, during the nonribosomal peptide synthetase (NRPS). While A domains have been well characterised due to their role in selectivity of the monomers and functioning as a gate keeper in the NRPS biosynthesis, C domains have been a subject of debate as they have not demonstrated signs of “A-domain like” side chain selectivity of its acceptor side. Here, we report our biochemical and structural characterisation of the selectivity of the fuscachelin C3-domain showing that it is not broadly flexible for monomers at the acceptor site, suggesting the need to consider C-domain mutation regarding future NRPS engineering.

RNA-seq transcription analysis of Herbaspirillum seropedicae phaC1 mutant strain in comparison with the wild type strain (SmR1)

Project description:In this study, we have investigated the physiological consequences of PHB (poly(3-hydroxybutyrate)) synthesis in H. seropedicae by characterising the trancriptional changes in a mutant strain lacking phaC1 gene which codes for the PHA synthase enzyme essential for the last step in the synthesis of PHB. To do this experiment both wild type (SmR1) and phaC1 mutant were cultured on Nfb-Malate-HP media suplemented with 20 mM of ammonium chloride under 30 Celsius degrees and 120 rpm shaking rate until the late log-phase (O.D600 = 1.0), when the peak of PHB production is observed. The cultures obtained as above were harvested for RNA extraction and transcriptome analysis.

The tinkerbell (tink) mutation identifies the dual-specificity MAPK phosphatase INDOLE-3-BUTYRIC ACID-RESPONSE5 (IBR5) as a novel regulator of organ size in Arabidopsis.

Project description:Mitogen-activated dual-specificity MAPK phosphatases are important negative regulators in the MAPK signalling pathways responsible for many essential processes in plants. In a screen for mutants with reduced organ size we have identified a mutation in the active site of the dual-specificity MAPK phosphatase INDOLE-3-BUTYRIC ACID-RESPONSE5 (IBR5) that we named tinkerbell (tink) due to its small size. Analysis of the tink mutant indicates that IBR5 acts as a novel regulator of organ size that changes the rate of growth in petals and leaves. Organ size and shape regulation by IBR5 acts independently of the KLU growth-regulatory pathway. Microarray analysis of tink/ibr5-6 mutants identified a likely role for this phosphatase in male gametophyte development. We show that IBR5 may influence the size and shape of petals through auxin and TCP growth regulatory pathways. 6 samples, three mutant replicates, three wild type replicates.

Understanding condensation domain selectivity in non-ribosomal peptide biosynthesis: structural characterization of the acceptor bound state

Project description:Non-ribosomal peptide synthetases are important enzymes for the assembly of complex peptide natural products. Within these multi-modular assembly lines, condensation domains perform the central function of chain assembly, typically by forming a peptide bond between two peptidyl carrier protein (PCP)-bound substrates. In this work, we report the first structural snapshots of a condensation domain in complex with an aminoacyl-PCP acceptor substrate. These structures allow the identification of a mechanism that controls access of acceptor substrates to the active site in condensation domains. The structures of this previously uncharacterized complex also allow us to demonstrate that condensation domain active sites do not contain a distinct pocket to select the side chain of the acceptor substrate during peptide assembly but that residues within the active site motif can instead serve to tune the selectivity of these central biosynthetic domains.

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.

Single-nucleus sequencing deciphers lineage trajectories in rice pistils [snRNA-seq]

Project description:Angiosperms possess a characteristic life cycle with an alternation of sporophyte and gametophyte generations, which happens in plant organs like pistils. Rice pistils contain ovules and receive pollen for successful fertilization to produce grains. The cellular expression profile in rice pistils is largely unknown. Here we show a cell atlas of rice pistils before fertilization by droplet-based single-nucleus RNA sequencing. The Ab initio marker identification validated by in situ hybridization assists the cell-type annotation, revealing cell heterogeneity between ovule and carpel lineages.
