Semi-quantitative gene expression analysis of some photosynthesis and capsaicin-related genes under elevated CO2 and temperature. Effects of different levels of carbon dioxide (CO2) and temperatures (oC) on semiquantitative RT-PCR expression of key genes of photosynthesis Capsicum chinense chlorophyll A/B, Cccapsaisin synthase I, CcSPS, CcRUBP, Cccatalase of the two  germplasm of Bhut Jolokia subjected to different treatments. Different treatments given were: CTGT I (380 ppm CO2 + ambient temperature), CTGT II (550 ppm CO2 + 2 °C higher than ambient from flower bud initiation till maturity) and CTGT III (750 ppm CO2 + 4 °C higher than ambient from flower bud initiation till maturity), normal field conditions. Bars with different letters are statistically different from each other (n = 6)
