(Submitter supplied) The transcriptomic analysis of nkd1, nkd2 and o2 homozygous mutant set (including 1 WT, 3 single mutants, 3 double mutants and 1 triple mutant) at 8, 12 and 16 DAP revealed temporal regulatory landscape in endosperm grain-filling stage. The data also showed NKD1, NKD2 and O2 interactively regulate gene network overtime in several processes, such as hormone response, cell wall organization, nutrient storage and endoreduplication, etc.

(Submitter supplied) In this work, we used chromatin immunoprecipitation coupled with high throughput sequencing (ChIP-seq) to ascertain the genome-wide occupancy of ZmDDM1 in maize genome. The results revealed that ZmDDM1 recognized an 8-bp-long GC-rich degenerate DNA sequence motif, which is enriched in transcription start sites (TSSs) and other euchromatic regions. Meanwhile, 24-nucleotide siRNAs and CHH methylation were delineated at the edge of ZmDDM1-occupied sites. more...

(Submitter supplied) As a key member of the grass-specific subclade of argonaute proteins, AGO18b protein has been proposed to bind 24-nt meiotic phasiRNAs based on their co-expression in tapetal and meiotic cells. Here we show that expression of in maize tassels is strictly induced by developmental stages. Interestingly, reduced expression of AGO18b in both Mutator-mediated (ago18b::mum) and RNAi mutants leads to an increase in plant height and tassel length, suggesting its non-meiotic function as a negative regulator of SAM/IM maintenance. more...

(Submitter supplied) We sequenced mRNA from from four segments along a developing 9 day old third maize leaf of WT W22 accession and ZmDCT2 KO (in W22 background - dct2-1::Ac) plants, to identify changes in gene expression in dct2-1::Ac as a response to the loss of ZmDCT2 function.

(Submitter supplied) Transcriptome profiles of MATZ and BETL tissues are compared across three stages of development. Sugars and other nutrients unloaded from vascular tissues in the MATZ are imported by the BETL for utilization by the developing endosperm. Pronounced changes in gene expression occur in both tissues during kernel development.
