Drosophila TRPA1 (DTRPA1)[32], [35], [36], Pyrexia [37], and Painless [33], [38], [39], all of which are TRPA
subfamily members, respond to «warm» or «hot» temperatures and are required
for various temperature - related behaviors (The temperature thresholds are 24 — 29 °C, 37.5 — 40 °C, and 42 — 45 °C,
for DTRPA1, Pyrexia, and Painless, respectively).
One of three members of the Sequoioideae
subfamily of cypress trees, the coast redwoods and their cousins, the giant sequoias (Sequoiadendron giganteum), hold the records
for tallest and largest trees in the world, respectively.
