Description The present study reports profiling of the elevated carbon
dioxide (CO2) concentration responsive global transcriptome
in chickpea, along with a combinatorial approach for
exploring interlinks between physiological and transcriptional
changes, important for the climate change scenario.
Various physiological parameters were recorded in two
chickpea cultivars (JG 11 and KAK 2) grown in open top
chambers under ambient [380 parts per million (ppm)]
and two stressed/elevated CO2 concentrations (550 and
700 ppm), at different stages of plant growth. The elevated
CO2 concentrations altered shoot and root length, nodulation
(number of nodules), total chlorophyll content and nitrogen
balance index, significantly. RNA-Seq from 12 tissues
representing vegetative and reproductive growth stages of
both cultivars under ambient and elevated CO2 concentrations
identified 18,644 differentially expressed genes including
9,687 transcription factors (TF). The differential regulations
in genes, gene networks and quantitative real-time
polymerase chain reaction (qRT-PCR) -derived expression
dynamics of stress-responsive TFs were observed in both
cultivars studied. A total of 138 pathways, mainly involved
in sugar/starch metabolism, chlorophyll and secondary
metabolites biosynthesis, deciphered the crosstalk operating
behind the responses of chickpea to elevated CO2
concentration.
