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.
