BIOL 1521 Lecture Notes - Lecture 3: Auxin, Germination, Gravitropism
Document Summary
From activities associated with each of the following class topics, students should be able to: 3. 01 introduction to chemical signaling and movement: identify fundamental mechanisms of signaling pathways between cells and within cells. Between cells via hormones (in far proximity): endocrine. Endocrine / neural / neural-endocrine: evaluate role of cell signaling pathways in life history and pathogenicity (the manner of development of a disease) of microbes (e. g. myxobacteria, pseudomonas. , staphylococcus, Myxobacteria: individual rod-shaped cells aggregation in process to form a little lump spore-forming structure (fruiting body) fruiti(cid:374)g bodies are all that"s left over; (cid:374)o (cid:373)ore individual rod-shaped cells. Aggregation can also be utilized in predation events on other bacteria. Myxobacteria produce a number of biomedically and industrially useful chemicals, such as antibiotics, and export those chemicals outside of the cell. Pseudomonas: biofilm some free living bacteria attach to a surface makes microcolonies. When there are enough bacteria, quorum sensing is triggered this makes a mature biofilm community.
