(Submitter supplied) In dicots, proplastids present in the central region of L2 layer of SAM that lack chlorophyll-binding proteins and thylakoid membranes, give rise to all green tissues of plants. These cells after a few cell divisions, reach to the periphery of the SAM, near the interface with the primordial leaves and acquire thylakoid membranes during this transition. We obtained [(i) proplastid containing, CZ, (ii) partially developed thylakoids containing, PZ and (iii) highly developed thylakoids containing, LP samples along this gradient with Laser microdissection, based on Chlorophyll fluorescence identification of cells. more...

(Submitter supplied) Shoot apical meristem (SAM) of higher plant composed of a few distinct cell types. All the cells in a mature plant’s SAM derived from 30~35 stem cells reservoir which are located at the tip of the apex. Plants ability to give rise diverse cell types from a pool of pluripotent stem cells requires orchestrated gene network that controls the cell fate commitment during the meristem development. To understand, how gene regulatory networks control cell identities switches during cell differentiation requires resolution in recording their gene expression pattern at single cell resolution. more...

(Submitter supplied) Loss of function mutations in the narrow sheath (ns) duplicate genes (ns1 and ns2) cause the deletion of a mediolateral domain from maize leaves. The ns genes encode duplicate WUSCHEL1-like homeobox (WOX) putative transcription factors that function redundantly and non-cell autonomously to direct recruitment of leaf founder cell-initials in a lateral domain of the shoot apex. In order to investigate the genetic mechanisms of NS1 gene function, SAM-specific transcriptional profiling of narrow sheath mutant1-R comparing to that of nonmutant using laser microdissection microarray. more...

(Submitter supplied) Plants adjust their growth in response to environmental cues by forming new organs in different development contexts. Underground lateral roots initiate from prepatterned cells in the main root, but cells can also bypass the root/shoot trajectory separation and generate shoot-borne-roots through an unknown mechanism. Here, we mapped tomato (Solanum lycoperiscum) shoot-borne-roots development at single-cell resolution and show that they initiate from differentiated phloem-associated cells via a unique transitional stem-cell-like state. more...

(Submitter supplied) The purpose of this dataset is to generate a transcriptomic series of staged non-induced lateral root intiation in M82 tomato. Sections of the primary roots containing lateral roots at 5 different developemental stages (staged by their anatomy and expression of the auxin response marker DR5) were collected.

(Submitter supplied) Arabidopsis fc2-1 mutants fail to properly de-etiolate after a prolonged period in the dark. Our goal was to monitor whole genome expression during the first 2 hours of de-etiolation to determine the cuase of this growth arrest. In comparison with other mutants that also affect de-etiolation, we identified a subset of genes specifically regulated by FC2 function during de-etiolation.

(Submitter supplied) Arabidopsis HMA4 transformation facilitates Zn root-to-shoot translocation, but in Zn-supply dependent manner. It implies that distinct effects of HMA4 expression on Zn root:shoot distribution in transgenics grown under different Zn supply regimes results from the interaction between the transgene activity and the molecular background of the host plant. Microarray analysis was performed to compare expression profiles in leaves of transgenic and WT-plants grown in the presence of 5 µM Zn to identify the molecular mechanism underlying the difference in Zn root:shoot distribution between 35S:AtHMA4-expressing and wild-type tomato. more...

(Submitter supplied) Ectopic expression of AtHMA4 in tomato modified Zn accumulation in a Zn-supply dependent manner. It suggests that HMA4-expression under a range of Zn-supply differentially modifies the expression of endogens, which contributes to different Zn-related phenotypes. To identify genes differentially regulated in 35S:AtHMA4-expressing and wild-type tomato, the transcription profiles were compared between roots of transgenic and WT-plants grown in the presence of 5 µM Zn. more...

(Submitter supplied) N6-methyladenosine (m6A) represents the most prevalent internal modification on messenger RNA, and requires a multicomponent m6A methyltransferase complex in mammals. How their plant counterparts determine the global m6A modification landscape and its molecular link to plant development remain elusive. Here we show that FKBP12 INTERACTING PROTEIN 37 KD (FIP37) is a core component of the m6A methyltransferase complex, which underlies control of shoot stem cell fate in Arabidopsis. more...

(Submitter supplied) The shoot apical meristem (SAM) contains undifferentiated stem cells that are responsible for the initiation of above-ground organs, and eventually the general architecture of the plant. To gain insight into the nature of genetic programs and the regulatory networks underlying SAM function in soybean, we have used Affymetrix soybean GeneChip® to investigate the transcript profiles associated with micro-dissected SAMs or axillary meristems (AMs). more...
