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 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).

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

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

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.

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.

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.

Reactions triggered in response to the presence of a fungus 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.

A vacuole to which materials ingested by endocytosis are delivered.
