Their development is supported by a tapetum, which contains callase, and their walls have Â an (*) intine and extine layer.
In one species, these structures' surface expresses the SCR/SP11, which activates the SRK kinase, while in Solanaceae they use the S-locus to express PiSLF, which inactivates S-locus RNAses. One structure created by them interacts with the synergid cells of another structure to upregulate the FERONIA pathway, and respond to LURE chemoattractants. Their development is supported by a tapetum, which contains callase, and their walls have Â an (*) intine and extine layer. Created in the microsporangium, they contain a generative nucleus and a tube nucleus, the latter of which creates a structure that threads through the micropyle after it's deposited on the tip of the style. For 10 points, name these structures produced in anthers and carried by bees and other insects, which contain the male sex cells of plants.
