3. In 2010, NASA sent Arabidopsis seeds to the International Space station and grew them under zero gravity conditions. To their surprise, the plants germinated and developed shoot and root systems growing in opposite directions and the root showed patterns of normal root growth behavior. What might this suggest about gravity's role in plant seed germination and development and how do you think plants were able to diversify shoot and root systems without gravity?

"Conservative and compensatory evolution in oxidative phosphorylation complexes of angiosperms with highly divergent rates of mitochondrial genome evolution" Article Abstract Interactions between nuclear and mitochondrial gene products are critical for eukaryotic cell function. Nuclear genes encoding mitochondrial-targeted proteins (N-mt genes) experience elevated rates of evolution, which has often been interpreted as evidence of nuclear compensation in response to elevated mitochondrial mutation rates. However, N-mt genes may be under relaxed functional constraints, which could also explain observed increases in their evolutionary rate. To disentangle these hypotheses, we examined patterns of sequence and structural evolution in nuclear- and mitochondrial-encoded oxidative phosphorylation proteins from species in the angiosperm genus Silene with vastly different mitochondrial mutation rates. We found correlated increases in N-mt gene evolution in species with fast-evolving…

Question:- What would be the effect on flowering time of over-expressing VIN3 (i.e., 35S:VIN3) in a winter annual Arabidopsis plant grown adjacent to a summer annual wild type plant in long days under warm conditions? Assume that the plants germinate at the same time. In answering the question, describe the molecular mechanism that allows you to make this conclusion.
