“…Even wheat and rice show considerable variation between genotypes (Ali et al 2006;Munns and Tester 2008) and in tetraploid wheat (Triticum turgidum), this variability is, significantly, not correlated with the extent of Na + exclusion (but see Munns and James 2003;Genc et al 2007). A poor correlation between Na + exclusion and tolerance was also reported for rice (Yeo et al 1990).…”

Abstract. The successful integration of activity in saline environments requires flexibility of responses at all levels, from genes to life cycles. Because plants are complex systems, there is no 'best' or 'optimal' solution and with respect to salt, glycophytes and halophytes are only the ends of a continuum of responses and possibilities. In this review, I briefly examine seven major aspects of plant function and their responses to salinity including transporters, secondary stresses, carbon acquisition and allocation, water and transpiration, growth and development, reproduction, and cytosolic function and 'integrity'. I conclude that new approaches are needed to move towards understanding either organismal integration or 'salt tolerance', especially cessation of protocols dependent on sudden, often lethal, shock treatments and the embracing of systems level resources. Some of the tools needed to understand the integration of activity and even 'salt stress' are already in hand, such as those for whole-transcriptome analysis. Others, ranging from discovery studies of the nature of the cytosol to expanded tool kits for proteomic, metabolomic and epigenomic studies, still need to be further developed. After resurrecting the distinction between applied stress and the resultant strain and noting that with respect to salinity, the strain is manifest in changes at all -omic levels, I conclude that it should be possible to model and quantify stress responses.

“…Therefore, developing drought-and salt-tolerant cultivars is an important strategy to reduce risk and increase rice productivity (Blumwald and Grover 2006). Over the past decade, extensive efforts have been devoted to developing drought-and/or salt-tolerant rice cultivars (Ali et al 2006;Bernier et al 2008;Kumar et al 2008;Swamy et al 2011Swamy et al , 2017Chai et al 2013;Swamy and Kumar 2013;Wang et al 2013;Bimpong et al 2016;Ali et al 2017). These cultivars were mostly developed through conventional cross-pedigree breeding and marker-assisted backcross breeding approaches to enhance the ability of modern rice varieties to tolerate drought and salinity stresses by using diverse rice accessions.…”

“…There is a need for developing restorer lines with improved combining ability along with multiple abiotic stress tolerance traits. As higher GY and drought and salinity tolerance are highly complex and quantitative traits that are governed by multiple genes/QTLs, and there are lots of cryptic beneficial alleles (Ali et al 2006), through conventional cross-pedigree breeding approaches, it is difficult to use and pyramid all of these genes at one time.…”

“…Rice production is adversely affected by numerous biotic and abiotic stresses, including diseases and pests, cold, drought, flooding, heat, and salinity. Among them, drought and salinity are the major abiotic constraints that reduce GY, especially in Asia, whose population grows and consumes approximately 90% of rice (Ali et al 2006). Drought is the major stress that brings about severe yield reductions in rainfed upland areas across countries in South and Southeast Asia .…”

Recurrent selection breeding by dominant male sterility for multiple abiotic stresses tolerant rice cultivars

et al. 2017

Recurrent selection has not been extensively applied in rice breeding practices due to lack of male sterility genes. Recently, a male sterile line (named as 'Jiabuyu') controlled by a novel single dominant gene was found, which provides an ideal tool for rice recurrent selection breeding. Here, two different kinds of recurrent selection populations facilitated for outcrossing by the dominant male sterile line 'Jiabuyu' were developed, that included one population using 31 abiotic stress tolerance introgression lines with common recipient parent as founders, and the other one using 25 popular restorers lines applied in hybrid breeding as founders. After two cycles of recurrent selection through natural outcrossing, the seeds from male fertile progeny plants were screened for higher grain yield under normal irrigated, drought, and salt-stressed natural field conditions. Finally, we identified 11 promising high-yielding lines under irrigated conditions, 12 drought-tolerant and 12 salt-tolerant lines. Among them, one line gave higher grain yield across all three conditions, three lines yielded high in both irrigated and drought conditions and another three lines gave high yields in both drought and salt-stressed conditions. The present study was a commendable attempt at utilizing recurrent selection population facilitated by dominant male sterile line to improve rice complex traits, which provided valuable lessons for other rice breeders. The developed lines are promising to be rice varieties with high yield, drought and/or salinity tolerances.Yunlong Pang, Kai Chen, and Xiaoqian Wang have contributed equally to this work.

“…They influence the metabolism, photosynthesis and enzyme activity, and lead to a dramatic reduction of yields and to deterioration of the output quality. The physiological condition of plants is indicative of plant productivity and adaptability to stress and it is a general indication of the environment in which they grow (Alia et al, 2006;Gray et al, 2010). Research on biotic stresses includes the molecular mechanisms used by viruses, bacteria, fungi, and nematodes to incite disease and those used by plants to resist infection (Li et al, 2008;Yang et al, 2009;Delalieux et al, 2009b).…”
