Question

Indicate true (T) and false (F) statements below regarding signaling in plants. Your answer would be a four-letter string composed of letters T and F only, e.g. TTTF.

( ) Since multicellularity evolved before the divergence of the plant and animal lineages, plants have homologs of most animal signaling proteins, such as nuclear receptors, Ras, JAK, and Notch.

( ) Receptor tyrosine kinases are the largest class of cell-surface receptors in plant cells.

( ) Both plants and animals use cyclic GMP, NO, and Ca²⁺ for cell signaling.

( ) Leucine-rich repeat (LLR) receptor kinases are the most abundant type of receptor serine/threonine kinases in plants.

Answer 1

FTFF

1. First is wrong because after completely sequencing a widely small flowering plants , Arabidopsis thaliana , there were no homologs of Ras, JAK and Notch.

2. Receptor tyrosine kinasak are the largest class of cell surface receptors in plant cells.
