Any biological process involved in the maintenance of the steady-state number of cells within a population of cells in the meristem.

A series of molecular signals mediated by the detection of brassinosteroid.

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

A series of molecular signals mediated by the detection of brassinosteroid.

The process in which the microsporocyte undergoes meiosis, giving rise to four haploid microspores.

The process in which the microsporocyte undergoes meiosis, giving rise to four haploid microspores.

The final stages of microgametogenesis after the trinucleate stage has been reached resulting in viable pollen grains.

The process of introducing a phosphate group on to a protein.

The process of introducing a phosphate group on to a protein.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the Golgi apparatus.

The process whose specific outcome is the progression of the embryo over time, from zygote formation to the end of seed dormancy. An example of this process is found in Arabidopsis thaliana.

The process that occurs in a leaf near the end of its active life that is associated with the dismantling of cell components and membranes, loss of functional chloroplasts, and an overall decline in metabolism.

The controlled shedding of floral organs.

The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation).

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a peptide stimulus.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a peptide stimulus.

Reactions triggered in response to the presence of oomycetes that act to protect the cell or organism.

The process of introducing a phosphate group on to a protein.

Any biological process that results in permanent cessation of all vital functions of a cell. A cell should be considered dead when any one of the following molecular or morphological criteria is met: (1) the cell has lost the integrity of its plasma membrane; (2) the cell, including its nucleus, has undergone complete fragmentation into discrete bodies (frequently referred to as apoptotic bodies). The cell corpse (or its fragments) may be engulfed by an adjacent cell in vivo, but engulfment of whole cells should not be considered a strict criteria to define cell death as, under some circumstances, live engulfed cells can be released from phagosomes (see PMID:18045538).

The series of events in which a brassinosteroid stimulus is received by a cell and converted into a molecular signal.

The process that occurs in a leaf near the end of its active life that is associated with the dismantling of cell components and membranes, loss of functional chloroplasts, and an overall decline in metabolism.

A process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a chitin stimulus.

Initiation of a somatic embryo-an embryo arising from previously differentiated somatic cells, rather than from fused haploid gametes.

A process in which a protein transports or maintains the localization of another protein to the nucleus.

Any process that modulates the frequency, rate or extent of the growth of all or part of an organism so that it occurs at its proper speed, either globally or in a specific part of the organism's development.

Any process that stops, prevents, or reduces the frequency, rate or extent of growth of an organism to reach its usual body size.

Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.

Any process that activates or increases the frequency, rate or extent of the innate immune response, the organism's first line of defense against infection.

The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation).

Reactions triggered in response to the presence of a fungus that act to protect the cell or organism.

Reactions triggered in response to the presence of a virus that act to protect the cell or organism.

Any process that decreases the rate or frequency of cell death. Cell death is the specific activation or halting of processes within a cell so that its vital functions markedly cease, rather than simply deteriorating gradually over time, which culminates in cell death.

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

Any process that modulates the frequency, rate or extent of defense response to fungus.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

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

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A vacuole to which materials ingested by endocytosis are delivered.
