Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

Any series of molecular signals generated as a consequence of a pattern recognition receptor (PRR) binding to one of its physiological ligands. PRRs bind pathogen-associated molecular pattern (PAMPs), structures conserved among microbial species, or damage-associated molecular pattern (DAMPs), endogenous molecules released from damaged cells.

Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.

A response of an organism to a bacterium that prevents the occurrence or spread of disease.

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

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).

The initiation of the activity of the inactive enzyme MAP kinase (MAPK).

The process in which the growth of pollen tube is directed towards the female gametophyte.

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

Any process that decreases the rate, frequency, or extent of floral organ abscission, the controlled shedding of floral organs.

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 chitin 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 chitin stimulus.

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

Any process that activates or increases the frequency, rate or extent of defense response to bacterium.

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

The controlled shedding of a body part.

Any process that activates or increases the frequency, rate or extent of brassinosteroid mediated signaling pathway.

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

The double lipid bilayer enclosing the chloroplast and separating its contents from the rest of the cytoplasm; includes the intermembrane space.

The component of the plasma membrane consisting of the gene products that are tethered to the membrane only by a covalently attached anchor, such as a lipid group, that is embedded in the membrane. Gene products with peptide sequences that are embedded in the membrane are excluded from this grouping.

The region at growing end of the pollen tube cell, where polarized growth occurs.

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

A small organelle enclosed by a single membrane, and found in most eukaryotic cells. Contains peroxidases and other enzymes involved in a variety of metabolic processes including free radical detoxification, lipid catabolism and biosynthesis, and hydrogen peroxide metabolism.
