The joining together of exons from one or more primary transcripts of messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced.

Any process that modulates the frequency, rate or extent of flower development.

Organization of a region of tissue in a plant that is composed of one or more undifferentiated cells capable of undergoing mitosis and differentiation, thereby effecting growth and development of a plant by giving rise to more meristem or specialized tissue.

Any process involved in maintaining the size and shape of a root meristem.

Vascular tissue pattern formation as it occurs in the leaf of vascular plants.

The process that gives rise to a leaf. This process pertains to the initial formation of a structure from unspecified parts.

The developmental process that pertains to the organization of a leaf in three-dimensional space once the structure has initially formed.

Any process that modulates the frequency, rate or extent of the covalent addition of methyl groups to histones.

The process whose specific outcome is the progression of the carpel over time, from its formation to the mature structure. A carpel is an organ (generally believed to be a modified foliar unit) at the centre of a flower, bearing one or more ovules and having its margins fused together or with other carpels to enclose the ovule in an ovary, and consisting also of a stigma and usually a style.

The process whose specific outcome is the progression of the stamen over time, from its formation to the mature structure.

The process that gives rise to the sepal. This process pertains to the initial formation of a structure from unspecified parts.

Extra-nucleolar nuclear domains usually visualized by confocal microscopy and fluorescent antibodies to specific proteins.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

That part of the nuclear content other than the chromosomes or the nucleolus.

Extra-nucleolar nuclear domains usually visualized by confocal microscopy and fluorescent antibodies to specific proteins.

A spliceosomal complex that contains three snRNPs, including U5, bound to a splicing intermediate in which the first catalytic cleavage of the 5' splice site has occurred. The precise subunit composition differs significantly from that of the catalytic step 1, or activated, spliceosome, and includes many proteins in addition to those found in the associated snRNPs.
