James Santiago, a postdoc in Tom Sharkey’s lab was awarded an internal grant of $88,000 from the PRI for research on heat-sensitivity in tomato anthers and pollen grains using single cell RNA-sequencing.

Terpenes are natural chemicals that are used in medicines, fragrances, and industrial chemicals. The newly developed tool can add bits of foreign protein to the middle of an isoprene enzyme sequence. Proof of concept work on one terpene enzyme increased its production speed by over 25%.

The study reports that the activity levels of the carbon metabolism protein, G6PDH, are related to decreased production of pollen in bean flowers. As global temperatures rise, some bean crops, including Michigan-grown varieties, might be more sensitive to higher heat levels.

The lab of Thomas D. Sharkey have characterized a sucrose transporter protein found in common beans. The recently discovered protein, called PvSUT1.1, could help us understand how beans tolerate hot temperatures.

Isoprene and photosynthetic metabolism labeling experiments provided evidence that glucose is recycled back into photosynthetic metabolism.

The four-year, $898,946 grant from the National Science Foundation will allow Sharkey to continue his research on the evolutionary pattern of the appearance and loss of isoprene emission among various land plants and the impact of these emissions have on the atmosphere.

The Sharkey lab reports a correction for non-photosynthetic absorption of light in calculations of electron transport. Fluorescence measurements of electron transport are one way to determine crop productivity.

High levels of photosynthetic productivity can dangerously alter a plant cell's chemical balance. GPT2 is a sort of 'brake' that helps recycle and store extra resources that are produced during those times.
