From: Cold stress alters transcription in meiotic anthers of cold tolerant chickpea (Cicer arietinum L.)

Figure 4

Time after onset of cold stress at which the up-regulated genes showed maximum expression and down-regulated genes the maximum repression. The expression in up-regulated genes decreased after this time point whereas in down-regulated genes it either remained the same or increased. The expression in anthers of ICC16349 was studied using RT-qPCR at six time points (0 h, 1.5 h, 12 h, 24 h, 72 h and 120 h) after cold stress and is presented as fold change absolute compared to expression at 0 h. Chickpea actin gene acted as control and was used for normalization of expression data. The functions of the ESTs as per gene ontology are A140-2: signal transduction; AC47GE1: transcription; A36-2, A59-2, AC44GA2: carbohydrate metabolism; A10, A60: pollen development; A20, A118: transport; A114, A126-1: defense; A22, AC39GA2, AC41GF1: translation; A71-1: Cell division; A58, A62, A71-2, A77-2, A84-1, A95-1, A108-2, A155-1, A166, A170-1: unknown function. Panel (A), (B) show up-regulated and panel (C) down-regulated genes, respectively.
