- Wild type, winter annual accessions of Arabidopsis will flower after 20 days at 23C in long day conditions (critical photoperiod 15 hours) following 30 days at 4C. What is the predicted flowering- time response of each experimental plant's genotype (listed below) relative to a wild-type winter annual accession when both are grown from seed under the following experimental conditions? The possible flowering time responses are: EARLY, LATE, SAME relative to a wild-type winter annual grown under the environmental conditions listed below.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.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?

- Green fluorescent protein (GFP) can attach and mark other proteins with fluorescence, enabling scientists to see the presence of a particular protein. In an experiment to understand the molecular physiology behind the GA-induced seed germination, a GFP-tagged protein was observed to be moving from the cytoplasm into the nucleus of aleurone layer cells before the detection of alpha-amylase in the endosperm. Based on your knowledge, identify the possible protein(s) with which the GFP is attached in the given situation.

- This experiment is done in a thermal flask, will you be able to perform the same results (flask A with germinated seeds temperature increases and flask B with boiled seeds temperature remain unchanged), assuming you will be using a regular glass flask? Why?A group of students have carried out an experiment to investigate the relationship between the amount of growth hormone BAP in the culture medium and the growth of shoot.They have supplemented the medium with 4 different concentration of growth hormone which is (1 mg/L ,2 mg/L BAP,3 mg/L 4 mg/L) of BAP.According to the result after eight weeks, BAP at 2 mg/L had given better response with respect to shoot induction, shoot multiplication, length of shoot, and number of leaves per explants when compare with other amount of BAP. Discuss why?What is a feasible explanation why there is lesser percentage of germination and growth rate in monggo seeds when sprinkled with water added with 3/4 teaspoon as compared to monggo seed set-ups sprinkled with water?

Office : Aakash Towaa.os2 o72 Sa Shot by Souradeep Manna"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…Predict the phenotype of a flower in whichAPETALA-2 (activity A) and AGAMOUS (activity C) are expressednormally, but APETALA-3 and PISTILLATA (activity B) areexpressed in all four whorls.
