In order to meet the ever rising global demand for natural rubber, cultivation of Hevea is being extended to nontraditional regions of India where extreme climatic conditions like drought and low temperature negatively influence the crop performance. In order to ensure maximum productivity, identification of drought tolerant clones of Hevea which can cope up with stress and give better crop yield is essential. Several attempts have been made previously to identify genes that are associated with drought tolerance in Hevea. In the present study, quantitative expression analysis was made using quantitative PCR for seven drought associated transcripts in four clones of Hevea with varying levels of drought tolerance. Among the seven genes studied, Mitogen Activated Protein (MAP) kinase, Myeloblastosis (Myb) transcription factor, C-repeat responsive element/Dehydration Responsive Element (CRT/DRE) binding factor and Nuclear Factor Y subunit A (NFYA) showed a positive association with drought tolerance. Transcripts of ascorbate peroxidase and heat shock protein 70 (HSP 70) did not show any correlation with drought tolerance. Interestingly, catalase gene was found down regulated in all the clones under drought condition. The possible role of these genes based on their level of gene expression in four different clones of Hevea with varying levels of drought tolerance is discussed.

“…Resistance (R) genes with their functional sources against biotic and abiotic stresses could be used to gain improved crops with adaptation (Ahuja et al, 2010). Even though lack studies of R genes in diverse diseases in soybean, some promising NBS-LRR genes are reported to be associated with important traits related to disease resistance and tolerance to abiotic stresses.…”

“…However, more efforts are still needed due to less ability to encounter the stress challenges, especially to breed crops with enhanced resistance to multiple environmental stresses. The broad range of genes associated with resistance to the environmental stresses in many plants species has been progressed and may assist to develop new plant cultivars (Ahuja et al, 2010). The interlinked genetic and genomic features would make the improved crops achievable to encounter environmental stresses (Mochida and Shinozaki, 2010).…”

ABSTRAK Gen responsif terhadap cekaman lingkungan yang bertahan setelah mengalami duplikasi genom skala kecil merupakan bagian dari duplikasi genom. Namun demikian, informasi duplikasi gen yang berpengaruh terhadap sifat adaptif tanaman terhadap perubahan lingkungan masih terbatas. Ulasan ini menyajikan gambaran peristiwa duplikasi dalam genom tanaman yang berdampak terhadap duplikasi gen yang berkaitan dengan perubahan lingkungan, informasi duplikasi gen yang merupakan bagian dari mekanisme adaptasi, kasus duplikasi gen nucleotide-binding site-leucine-rich repeat (NBS-LRR) pada kedelai, dan implementasi informasi duplikasi gen terhadap pemuliaan kedelai di Indonesia. Peristiwa duplikasi genom menghasilkan duplikasi gen dan berperan terhadap evolusi adaptasi pada perubahan lingkungan. Informasi umum tentang tanaman yang beradaptasi dengan cekaman lingkungan memungkinkan untuk meningkatkan pemahaman kita tentang duplikasi gen sebagai mekanisme adaptasi. Gen-gen NBS-LRR yang terduplikasi diketahui berasosiasi dengan QTL terkait ketahanan penyakit dan ekspresi diferensialnya membuktikan kontribusi gen tersebut pada ketahanan kedelai terhadap cekaman biotik. Model yang diusulkan dari proses gen duplikasi NBS-LRR dapat membantu dalam memahami respons gen tersebut terhadap perubahan lingkungan. Duplikasi gen ketahanan terhadap hama/penyakit, NBS-LRR khususnya, memberikan informasi penting dalam pemilihan tetua pemuliaan dan pengembangan marka molekuler terkait ketahanan penyakit untuk memperbaiki kedelai di Indonesia secara genetik. Karena itu, sangat mungkin untuk meningkatkan program pemuliaan yang menargetkan gen ketahanan terhadap cekaman biotik/abiotik dan memberikan dasar molekuler sebagai strategi perlindungan tanaman terhadap cekaman dan pengembangan kultivar kedelai khusus untuk lingkungan ekstrim.Kata kunci: Cekaman lingkungan, duplikasi gen, hama/penyakit, kedelai, NBS-LRR.

“…Among the abiotic stresses, drought has a crucial devastating impact on agricultural production (Farooq et al 2009;Farooq et al 2012). Plants recruit complex overlapping mechanisms to reprogram their gene expression to cope with drought stress (Ahuja et al 2010;Golldack et al 2011). The orchestrated regulatory networks at transcriptional, post transcriptional and post translational levels are involved in forming the appropriate transcriptome and proteome of stress-exposed plants to show an adaptive response (Duque et al 2013;Mazzucotelli et al 2008).…”

It is of great significance to understand the regulatory mechanisms by which plants deal with drought stress. Two EST libraries derived from rapeseed (Brassica napus) leaves in non-stressed and drought stress conditions were analyzed in order to obtain the transcriptomic landscape of drought-exposed B. napus plants, and also to identify and characterize significant drought responsive regulatory genes and microRNAs. The functional ontology analysis revealed a substantial shift in the B. napus transcriptome to govern cellular drought responsiveness via different stress-activated mechanisms. The activity of transcription factor and protein kinase modules generally increased in response to drought stress. The 26 regulatory genes consisting of 17 transcription factor genes, eight protein kinase genes and one protein phosphatase gene were identified showing significant alterations in their expressions in response to drought stress. We also found the six microRNAs which were differentially expressed during drought stress supporting the involvement of a posttranscriptional level of regulation for B. napus drought response. The drought responsive regulatory network shed light on the significance of some regulatory components involved in biosynthesis and signaling of various plant hormones (abscisic acid, auxin and brassinosteroids), ubiquitin proteasome system, and signaling through Reactive Oxygen Species (ROS). Our findings suggested a complex and multi-level regulatory system modulating response to drought stress in B. napus.
