Abiotic stress, as an adverse environmental condition, seriously affects and limits
maize productivity worldwide. Climate changes lead to altering temperatures and
rainfall patterns. Earlier maize sowing enables avoiding high temperatures during
silking and pollination season. As a consequence of early sowing, damages
caused by temperatures lower than optimal can occur. Hence, it is very important
to know the mechanism of defence against the low temperatures in the early
developmental stages of the plant. Nowadays, thanks to hightroughput methods
such as Next Generation Sequencing (NGS), more profound and detailed research
can be conducted. A set of maize inbred lines important for commercial breeding
programs at Maize Research Institute, Zemun Polje was analysed by sequencing
the whole transcriptome. The aim was to identify tolerant lines for planning future
hybrids, try to unravel mechanism involved in maize response to low
temperatures and to identify molecul...ar markers that could be included in breeding
programs. Bioinformatic analysis of Single Nucleotide Polymorphisms (SNPs)
and Diferentially Expressed Genes (DEGs) was done. Cold-induced expression
analysis of several DEGs revealed different expression regulation dependent on
the duration of cold stress signalizing possible important role of these genes in
maize response to low temperatures. A more profound transcriptome analysis,
expected to give a comprehensive insight into low-temperature induced response
in early stages of plant development, is already underway. Besides low temperatures, waterlogging caused by more frequent rainfalls is another abiotic
stress which can hamper the idea of early sowing, especially if combined with
low-temperatures. For this reason, plant response to this stress will also be studied
on the same levels as low-temperature stress, with the final goal to develop
hybrids which can respond to challenging climate changes.
