Any process that modulates the frequency, rate or extent of secondary cell wall biogenesis.

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 salicylic acid stimulus.

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 jasmonic acid stimulus.

Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.

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

Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.

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 stimulus indicating an increase or decrease in the concentration of salt (particularly but not exclusively sodium and chloride ions) in the environment.

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 light stimulus, electromagnetic radiation of wavelengths classified as infrared, visible or ultraviolet light.

The process whose specific outcome is the progression of the pollen grain over time, from its formation to the mature structure. The process begins with the meiosis of the microsporocyte to form four haploid microspores. The nucleus of each microspore then divides by mitosis to form a two-celled organism, the pollen grain, that contains a tube cell as well as a smaller generative cell. The pollen grain is surrounded by an elaborate cell wall. In some species, the generative cell immediately divides again to give a pair of sperm cells. In most flowering plants, however this division takes place later, in the tube that develops when a pollen grain germinates.

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 an abscisic acid stimulus.

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 gibberellin stimulus.

The chemical reactions and pathways resulting in the formation of lignins, a class of polymers formed by the dehydrogenetive radical polymerization of various phenylpropanoid monomers.

A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of inextensible cellulose- and pectin-containing cell walls that are formed between the plasma membrane and primary cell wall after cell expansion is complete. An example of this is found in Arabidopsis thaliana.

The process in which the structures of a hair cell (trichome) cell are generated and organized. This process occurs while the initially relatively unspecialized epidermal cell is acquiring the specialized features of a hair cell. An example of this process is found in Arabidopsis thaliana.

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

Any process in which callose is transported to, and/or maintained in, a specific location. Callose is a linear 1,3-beta-d-glucan formed from UDP-glucose and is found in certain plant cell walls.

The process whose specific outcome is the progression of the pollen grain over time, from its formation as the microspore to the mature structure.

The process in which a seed trichome irreversibly increases in size in one

Any process that activates or increases the frequency, rate or extent of secondary cell wall biogenesis.

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.

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