Flood and drought are the two most prevalent abiotic stresses causing major yield reduction globally. In the last decade, molecular mechanisms of flood tolerance in rice have been revealed with successful release of flash flood-tolerant varieties to farmers. However, despite extensive research, the breakthrough of drought tolerance is still to come. In this review, we have examined the distribution and population types of drought-and flood-tolerant rice accessions, synthesized recent progresses of flood and drought tolerance research, and proposed a hypothesis that the molecular mechanisms of both drought and flood tolerance may be regulated by cross-talked pathways and coexist in aus subpopulation. We conclude that it is the time to mine the key regulator(s) of drought tolerance through de novo assembly of drought-tolerant aus landrace(s) with other molecular approaches and develop drought-tolerant rice using genome manipulation weaponry. 77

“…In addition, elite breeding lines tolerant to multiple abiotic stresses have been developed through conventional breeding (Gregorio et al 2002;Kumar et al 2008;Collard et al 2013a;Collard et al 2013b). Allele mining to tap new genes and novel beneficial alleles from diverse germplasm for abiotic stresses have also been explored (Fukao et al 2009;Li et al 2011;Niroula et al 2012;Iftekharuddaula et al 2016b;Shah et al 2016). The improved breeding lines developed from both conventional and molecular breeding and the available DNA markers can be used to develop new tolerant lines with multi-abiotic stress tolerance in more challenging areas, such as in the swampy lands.…”

Productivity of swampy land rice varieties in Indonesia remains low due to abiotic and biotic stresses. Iron toxicity, submergence and long-term flooding are common problems that affect plant growth, sometimes leading to total crop loss. Meanwhile, rice blast, rice tungro virus (RTV), and bacterial leaf blight (BLB) can also lead to severe yield loss. These stresses could be overcome by an integrative approach of cultural practices and planting multi-stress tolerant rice. Here we describe the development of new high-yielding varieties that are adapted to the swampy land environments in Indonesia with multi-stress tolerance to diverse abiotic and biotic stresses. Multi-environmental trials were performed in nine locations to screen for several abiotic and biotic stresses in the field and greenhouse in 2012 and 2013. This study identified promising rice lines that had high grain yield as well as tolerance to iron toxicity and submergence, resistance to BLB and RTV, and good grain quality. The best line was B11377F-MR-34-2, derived from a double cross among Cinglonik, IRBB7, Mamberamo and IR64. It was confirmed that this advanced breeding line carries the submergence tolerance gene, SUB1, through expression analysis of the SUB1A gene. Another promising line was B11586F-MR-11-2-2, having iron toxicity tolerance, resistance to RTV, and high milling recovery. Moreover, these lines have passed the Indonesian national variety release committee and have been named as Inpara8 and Inpara9, and are targeted for dissemination and adoption in the swampy areas.
