“…ABC proteins are primary transporters that mediate the energy-driven transport of a large and diverse multitude of substrates across biological membranes. ABC transporters play key roles in many physiological processes, such as plant development and plant nutrition, and in stress response (Moons 2008 ; Matsuda et al 2012 ; Jarzyniak and Jasinski 2014 ; Nguyen et al 2014 ; Saha et al 2015 ). In the rice genome, 133 genes coding for ABC transporters have been identified (Saha et al 2015 ).…”

In the rice genome, 133 genes coding for ABC transporters have been identified (Saha et al 2015 ). In our study, in 3 h-treated roots, 15 out of the 133 ABC transporter genes were modulated in the same way in the two cultivars, 4 and 7 ABC transporter genes were specifically up-regulated in Eurosis and Loto, respectively, and 14 and 3 ABC transporter genes were specifically down-regulated in Eurosis and Loto, respectively.…”

BackgroundRice (Oryza sativa L.) is one of the most important crops cultivated in both tropical and temperate regions and is characterized by a low water-use efficiency and a high sensitivity to a water deficit, with yield reductions occurring at lower stress levels compared to most other crops. To identify genes and pathways involved in the tolerant response to dehydration, a powerful approach consists in the genome-wide analysis of stress-induced expression changes by comparing drought-tolerant and drought-sensitive genotypes.ResultsThe physiological response to osmotic stress of 17 japonica rice genotypes was evaluated. A clear differentiation of the most tolerant and the most sensitive phenotypes was evident, especially after 24 and 48 h of treatment. Two genotypes, which were characterized by a contrasting response (tolerance/sensitivity) to the imposed stress, were selected. A parallel transcriptomic analysis was performed on roots and leaves of these two genotypes at 3 and 24 h of stress treatment. RNA-Sequencing data showed that the tolerant genotype Eurosis and the sensitive genotype Loto mainly differed in the early response to osmotic stress in roots. In particular, the tolerant genotype was characterized by a prompt regulation of genes related to chromatin, cytoskeleton and transmembrane transporters. Moreover, a differential expression of transcription factor-encoding genes, genes involved in hormone-mediate signalling and genes involved in the biosynthesis of lignin was observed between the two genotypes.ConclusionsOur results provide a transcriptomic characterization of the osmotic stress response in rice and identify several genes that may be important players in the tolerant response.Electronic supplementary materialThe online version of this article (doi:10.1186/s12284-016-0098-1) contains supplementary material, which is available to authorized users.

“…Monolignol aglycones, obtained through the action of ␤-glucosidases, are further released at the cell wall. Several ATPbinding cassette (ABC) transporters, which belong to a large multigene family, including indeed 128 genes in rice [26], are likely specifically involved in monolignol transports across membranes [27][28][29][30]. Other proteins are probably also involved, such as MATE (multidrug and toxic compound extrusion) efflux transporters because several family members were shown to be highly expressed in Eucalyptus xylem [31] .…”

“…Five such genes could even rescue the corresponding yeast mutant under heat stress (Sarkar et al 2013 ). Amongst transporters, rice genome was found to code for 33 calcium transporters, which included one channel, 14/15 ATPases and 16 exchangers (Goel et al 2011 ; Kamrul Huda et al 2013 ), 133 ABC transporters (Saha et al 2015 ) and 14 sulphate transporters. The sulphate transporters are expressed during sulphate starvation, heavy metal and abiotic stress as well as reproductive development (Kumar et al 2011 ).…”

Rice is one of the main pillars of food security in India. Its improvement for higher yield in sustainable agriculture system is also vital to provide energy and nutritional needs of growing world population, expected to reach more than 9 billion by 2050. The high quality genome sequence of rice has provided a rich resource to mine information about diversity of genes and alleles which can contribute to improvement of useful agronomic traits. Defining the function of each gene and regulatory element of rice remains a challenge for the rice community in the coming years. Subsequent to participation in IRGSP, India has continued to contribute in the areas of diversity analysis, transcriptomics, functional genomics, marker development, QTL mapping and molecular breeding, through national and multi-national research programs. These efforts have helped generate resources for rice improvement, some of which have already been deployed to mitigate loss due to environmental stress and pathogens. With renewed efforts, Indian researchers are making new strides, along with the international scientific community, in both basic research and realization of its translational impact.
