Indiana University-Purdue University Indianapolis (IUPUI) / The phototropin photoreceptors are important regulators of plant growth and development and can therefore affect the photosynthetic activity of plants. Phototropin1 and Phototropin2 are versatile protein kinases that become activated when exposed to blue light. Their photobiological actions are best understood in the model plant Arabidopsis thaliana, where they are known to trigger several responses to blue light, one of which is phototropism, the bending of plant organs towards light. Additionally, phot1 and phot2 drive stomatal opening, chloroplast arrangement in leaf cells, leaf expansion, and leaf orientation. The phot1-specific response is rapid inhibition of hypocotyl growth, leaf positioning and mRNA stability whereas phot2 mediates the chloroplast avoidance response to high light. These responses impact a plant’s ability to capture light for photosynthesis, therefore the phototropins play important roles in optimizing a plant’s photosynthetic activity. Soybean (Glycine max) is a very important crop plant in Indiana known for its nutritional versatility and is also utilized for biodiesel production.In spite of soybean being a key crop, there is currently no information about the functionality of soybean phototropins. Also, being a legume, soybean has many structural and functional features that are not present in Arabidopsis. Interestingly, PsPHOT1A (a photoreceptor from garden pea) was found to be a functional phototropin as it was able to complement the phot1 mutation in Arabidopsis. The roles of these proteins in soybean will be elucidated based on the hypothesis that soybean phototropins play essential roles in regulating photosynthetic activity as do the Arabidopsis phototropins. To date, five soybean phototropins, 3 PHOT1s and 2 PHOT2s, are believed to exist. These GmPHOT protein coding regions were amplified by RT-PCR and cloned into pCR8/TOPO or pENTR-D/TOPO vectors via TOPO cloning to utilize Gateway cloning technology to create plant transformation constructs subsequently. The cloned GmPHOT cDNAs from each of the 5 GmPHOTs were sequenced and compared to the GmPHOT sequences from the Phytozome database to assess the accuracy of the gene models. The gene models of all the GmPHOTs were found to be accurate except that of GmPHOT1B-2. The high level of sequence identity between the GmPHOTs and AtPHOTs and the conservation of LOV domains and catalytic domains indicate structural resemblance between them. This suggests that soybean phototropins should encode active photoreceptors. The cloned protein coding regions from soybean were then recombined into a plant expression vector via Gateway technology,which were then used for transformation of Agrobacterium tumefaciens. These plant expression constructs will be utilized in the future to determine the functionality of soybean phototropins in Arabidopsis.
