The process by which excess light energy absorbed by chlorophyll and not used to drive photosynthesis is emitted as heat. This process helps maintain the balance between dissipation and utilization of light energy to minimize generation of oxidizing molecules, thereby protecting the plant against photo-oxidative damage.

The merging of the polar nuclei, the two nuclei contained within the same cell that are created from the mitotic division of the megaspore during angiosperm reproduction. Polar nuclear fusion takes place in the ovule, forming in the fusion nucleus and giving rise to the endosperm when fertilized.

The creation of a single nucleus from multiple nuclei as a result of fusing the lipid bilayers that surround each nuclei.

Synergid cells undergo degeneration and death in response to penetration by the pollen tube. It is an active process that involves a dramatic decrease in cell volume, collapse of the vacuoles, and complete disintegration of the plasma membrane and most organelles.

Any process that stops, prevents, or reduces the frequency, rate, or extent of toll-like receptor 5 signaling pathway.

The process in which boundaries between lateral organs and the meristem is established and maintained.

The regionalization process that specifies plant organ primordium boundaries resulting in a restriction of organogenesis to a limited spatial domain and keeping the organ separate from surrounding tissues.

The chemical reactions and pathways resulting in the formation of mucilage, a gelatinous substance secreted by plants.

The chemical reactions and pathways involving mucilage, a gelatinous substance secreted by plants.

Any 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 ozone stimulus.

OBSOLETE. The chemical reactions and pathways involving microRNA, a large family of 21-22 nucleotide non-coding RNAs with presumed post-transcriptional regulatory activity.

OBSOLETE. The chemical reactions and pathways resulting in the formation of microRNA, a large family of 21-22 nucleotide non-coding RNAs with presumed post-transcriptional regulatory activity.

Any process that activates or increases the frequency, rate, or extent of toll-like receptor 3 signaling pathway.

The process in which malonate(1-) is transported across a mitochondrial membrane, into or out of the mitochondrion.

The directed movement of malonic acid across a membrane.

The series of molecular signals initiated by a ligand binding to toll-like receptor 4.

The process in which coenzyme A is transported across a mitochondrial membrane, into or out of the mitochondrion.

The process in which coenzyme A is transported across a membrane. Coenzyme A, 3'-phosphoadenosine-(5')diphospho(4')pantatheine, is an acyl carrier in many acylation and acyl-transfer reactions in which the intermediate is a thiol ester.

Formation of cytochrome b6f complex, a complex that transfers electrons from reduced plastoquinone to oxidized plastocyanin and translocates protons from the stroma to the lumen, by the aggregation, arrangement and bonding together of its constituents.

The aggregation, arrangement and bonding together of a cytochrome complex. A cytochrome complex is a protein complex in which at least one of the proteins is a cytochrome, i.e. a heme-containing protein involved in catalysis of redox reactions.
