MetabolomicsMulti-omics Analysis Reveals Multiple Metabolic Processes, Phytohormone Signaling, and the Negative Regulatory Role of ZmPP2CA11 in Maize Seedling Water-Deficit Responses

In this study, the physiological phenotyping, RNA sequencing, widely targeted metabolomics, and phytohormone profiling were used to examine the responses of maize seedlings to progressive PEG-induced osmotic stress and their recovery after PEG removal.

MetabolomicsNatural polymorphism of ZmICE1 contributes to amino acid metabolism that impacts cold tolerance in maize

Cold stress negatively affects maize (Zea mays L.) growth, development and yield. Metabolic adjustments contribute to the adaptation of maize under cold stress. We show here that the transcription factor INDUCER OF CBF EXPRESSION 1 (ZmICE1) plays a prominent role in reprogramming amino a...

TranscriptomicsDifferential transcript accumulation in seedling and mature shoots identifies components contributing to corn earworm resistance
As maize seedlings germinate into the soil, they encounter an environment teeming with insects seeking rich sources of nutrition. Maize presumably has developed a number of molecular mechanisms to ensure survival at the beginning of its life cycle. Bioassays indicated maize seedlings were more to...

ProteomicsLC-MS/MS analysis of maize seedling leaf bases
1 g samples of maize seedling leaf bases were collected from the wild-type (Zheng58) plants and the mutants (bzu3-2). we undertook glycoproteomics analyses of the N-glycans. Based on the libraries of maize protein group and plant N-glycosylation modification in the Uniprot database, we identified 2,...

ProteomicsLarge-scale Identification and Time-course Quantification of Ubiquitylomes in De-etiolating Maize Seedling Leaf
Ubiquitylation is a widely known post-translational modification that regulates myriad biochemical and physiological events in organism. The ubiquitin system is crucial for the development and fitness of higher plants. The process of de-etiolation, during which green plants initiate photomorphogenes...

TranscriptomicsThe maize leaf transcriptome
We have generated over 80 million 32 nt reads generated from RNA samples isolated from the tip and base of a developing Mo17 leaf. A comparision of these data with the maize AGP resulted in the confirmation of approximately 88% of the maize filtered gene set Keywords: Transcriptome analysis Examin...

TranscriptomicsDevelopmental Dynamics of Kranz Cell Transcriptional Specificity in Maize Leaf Reveals Early Onset of C4-related Processes
The comparison of the cell-specific transcriptomes of bundle sheath (BS) and mesophyll (M) cells from successive developmental stages of maize leafs reveals that the number of genes preferentially transcribed in one cell type or the other varies considerably from the sink-source transition to mature...

TranscriptomicsIdentification of stress response and recovery mechanisms by multi-scale analyses of drought effect in the maize leaf growth zone.
We use the gowth zone of the maize leaf as a model system to study the growth reduction in response to drought stress. The spatial gradient and the relatively large size of the maize leaf allowed us to sample at a subzonal rezolution and to examine different developmental stages at the same time. W...

MetabolomicsWheat growth, applied water use efficiency and flag leaf metabolome under continuous and pulsed deficit irrigation

The intensity and frequency of precipitation events are predicted to change over the coming decades. For many areas, longer periods without rainfall are expected. We investigated the importance of irrigation frequency under water deficit conditions for growth, physiology and chemistry of wheat (<...

ProteomicsComparative proteomic analysis of maize (Zea may L.) seedlings under rice black-streaked dwarf virus infection
Maize rough dwarf disease (MRDD) is a severe disease that has been occurring frequently in southern China and many other Asian countries. MRDD is caused by the infection of Rice black streaked dwarf virus (RBSDV) and leads to significant economic losses in maize production. To well understand the de...
