Developmental changes in transcriptomes of two key transport tissues in maize kernels: The Maternal Transfer Zone (MATZ) and Basal Endosperm Transfer Layer (BETL). Zea mays

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. Overall design: RNAseq data were obtained from duplicate tissue samples isolated by cryomicrodissection of developing maize kernels at three developmental time points; 8 days post-pollination (DAP), 14 DAP and 20 DAP.

本数据集比较了母本转运区（MATZ）与基部胚乳转运层（BETL）组织在三个发育阶段的转录组谱（Transcriptome profiles）。由母本转运区（MATZ）维管组织卸载的糖类及其他营养物质，将被基部胚乳转运层（BETL）摄取以供发育中的胚乳利用。在籽粒发育过程中，两种组织的基因表达均发生显著变化。整体实验设计：从授粉后8天（DAP）、14 DAP及20 DAP三个发育时间点的玉米发育籽粒中，通过冷冻显微切割（cryomicrodissection）技术分离得到两份重复组织样本，进而获取RNA测序（RNAseq）数据。
