A phylogenetic tree<span> or evolutionary </span>tree<span> is a branching diagram or "</span>tree<span>" showing the inferred evolutionary relationships among various biological species or other entities—their </span>phylogeny<span>—based upon similarities and differences in their physical or genetic characteristics.</span>
As given in the graph, mutation in this gene causes a decline in the production of glucose as it obstruct the process of photosynthesis.
<h3>What is psaB gene?</h3>
P700, the primary electron donor of photosystem I (PSI), as well as the electron acceptors A0, A1, and FX, are bound by PsaA and PsaB.
As given in the graph, mutation in this gene causes a decline in the production of glucose as it obstruct the process of photosynthesis.
Thus, the plant with the mutated psaB gene was dying.
