The overall objectives and mission is as follows:
- To understand mechanisms of plant responses to several environmental factors (temperature, atmospheric carbon dioxide concentration, ultraviolet-B radiation, water deficits, nutrition etc.) at the biochemical, leaf and canopy level in the controlled environments to observations of whole systems in the field.
- Advance the development of mechanistic crop simulation models and remote sensing algorithms to understand crop physiology and evaluate crop management strategies and physiological traits for genetic yield improvement.
- Apply modeling tools for crop production management, and policy decision of the impact of climate perturbations on crop production.
Papers published in 2007 and 2008 heighlighting singificant fidings are.

- 2007 - Dr. Kakani and Reddy studied Temperature response of C 4 species big bluestem (Andropogon gerardii) is modified by growing carbon dioxide concentration. Environmental and Experimental Botany 61: 281-290.
- 2007 - Dr. Reddy and his colleagues provided a comphrehensive review on the "Influence of high temperature and breeding for heat tolerance in cotton: A review" published in Advances in Agronomy, 93: 313-385.
- 2007 - Dr. Reddy and his colleagues explored pollen-based screening of soybean genotypes for high temperatures. This research entitled "Polleb-based screening of soybean genotyes for high temperatures" was published in Crop Science 47: 219-231, and was highlighted in CSANews, February 2007, V52, NO2, Pages 5-6.

Canopy reflectance in cotton for growth assessment by D. Zhao, K. Raja Reddy, V. Gopal Kakani, John J. Read, and Sailaja Koti, published in European Journal of Agronomy, 2007, 26 335–344.
- 2007. Reddy and Kakani used pollen-based screening methods as tool to identify pepper species tolerance to high temperatures originated from different countries - Screening Capsicum species of different origins for high temperature tolerance by in vitro pollen germination and pollen tube length by K. Raja Reddy and V.G. Kakani, Scientia Horticulturae 112 (2007) 130–135.
- 2007. Abiotic stress conditions cause extensive losses to agriculture goods and services worldwide. Crops in the future climate will be subjected to a combination of abiotic stresses in the field, genetic modifications of agronomic crops will likely be necessary to cope with changes projected in global climate. In this study, Reddy’s group explored multiple stresses alone or in combination on soybean growth and physiology - Effects of carbon dioxide, temperature and ultraviolet-B radiation and their interactions on soybean (Glycine max L.) growth and development by Sailaja Koti, K. Raja Reddy, V.G. Kakani, D. Zhao, and W. Gao, Environmental and Experimental Botany 60 (2007) 1–10.
- 2007. Over the recent years, UV-B radiation has increased and changes projected in UV-B and other biotic and abiotic stressors will have serious implications on crop performance. In this study, Reddy’s group investigated the "Effect of enhanced UV-B radition on reniform nematode (Rotylenchus reniformis Linford and Oliveira) populations in cotton (Gossypium hirsutum L.)" by S. Koti, K. R. Reddy, G.W. Lawrence, V.R. Reddy, V.G. Kakani, D. Zhao and W. Gao. Plant Pathology Journal 6 (2007), 51-59.
