Monitoring the transcriptome changes of 14013 rice unigenes in response to drought by cDNA microarray

摘要

Environmental stresses, such as drought, high salinity, and low temperature, have adverse effects on plant growth and seed production. Plants have evolved a number of mechanisms to cope with different abiotic stresses. One important step in the control of the stress responses appears to be the transcriptional activation or repression of genes. Expression of many genes has been demonstrated to be induced by these stresses, including those encoding transcription factors; some have been identified havebeen shown to be essential for stress tolerance. Transcriptome analyses using microarray technology is very powerful and useful tool in identifying several genes that are induced by dehydration stress and these genes can further be classified into different functional groups (Katiyar et al, 2003, 2004).
