“…In proteomics studies, the analysis of the differentially expressed proteins in cultivar Enrei, under 72 hours of flooding, showed an increase of 1.5 and 3.6-fold in the concentration of the enzymes enolase and alcohol dehydrogenase 1, respectively (Khatoon et al, 2012). The cultivar studied presents a moderate tolerance to soil flooding (Nanjo et al, 2014), corroborating with the results of the present study, which identified higher levels of transcripts in tolerant soybean cultivars (Figure 2). However, the positive response of only one or few genes or mechanisms does not necessarily indicate that the genotype is stress-tolerant and maintains its development, necessitating a more thorough investigation of the flood response mechanism.…”

“…The identification of soybean cultivars with either the absence or insignificant alterations in grain yield under flooding are reported (Rhine et al, 2010), as well as the genetic variability for that trait (Nanjo et al, 2014). These studies present alterations in the metabolism that enable the adaptation to environments with low oxygen availability.…”

“…The elucidation of the mechanisms involved in the response of plants to flooding stress is indispensable and is the focus of a number of studies on soybean crops (Komatsu, Kobayashi, Nishizawa, Nanjo, & Furukawa, 2010;Khatoon, Rehman, Oh, Woo, & Komatsu, 2012;Nanjo et al, 2014), as well as many different species (Magneschi & Perata, 2009;Sasidharan et al, 2013;van Veen et al, 2016). RT-qPCR analysis (reverse transcription -quantitative polymerase chain reaction) is a tool utilized to evaluate the expression of genes involved in the response of soybean plants to flooding conditions (Nakayama et al, 2014;Valliyodan et al, 2014).…”

The flooded environment brings about injuries to soybeans that vary depending on the adaptation ability of the genotype. Oxygen deprivation promotes the induction of the expression of genes related to glycolysis and fermentation pathways to maintain energy metabolism and, in addition to reducing-power consuming processes, act in the formation of adaptive structures and the maintenance of the redox status of the plant. The aim of this work was to evaluate the relative expression of genes related to soil flooding response in two contrasting soybean cultivars. Soybean plants of the sensitive (BRS 154) and tolerant (I27) cultivars at the V1 development stage were submitted to the flooding and control conditions (without flooding) for 0, 24, 48, and 96 hours. The relative expression of genes associated with flooding, including enolase (ENO), alcohol dehydrogenase 1 (ADH1), alanine aminotransferase 2 (ALAT2), hemoglobin 1 (GLB1), LOB41 domain-containing protein (LBD41), xyloglucan endotransglycosylase (XETP) and ascorbate peroxidase (APX2), was evaluated by means of RT-qPCR. The relative expression, in general, increased with flooding, especially in the root tissue. Cultivar I27 responded positively as observed by the expression of the maintenance genes of energy metabolism, structural changes and detoxification, suggesting the presence of three tolerance mechanisms in the flooding response.

Climate change is considered a major threat to world agriculture and food security. To improve the agricultural productivity and sustainability, the development of high-yielding stress-tolerant, and climate-resilient crops is essential. Of the abiotic stresses, flooding stress is a very serious hazard because it markedly reduces plant growth and grain yield. Proteomic analyses indicate that the effects of flooding stress are not limited to oxygen deprivation but include many other factors. Although many flooding response mechanisms have been reported, flooding tolerance mechanisms have not been fully clarified for soybean. There were limitations in soybean materials, such as mutants and varieties, while they were abundant in rice and Arabidopsis. In this review, plant proteomic technologies are introduced and flooding tolerance mechanisms of soybeans are summarized to assist in the improvement of flooding tolerance in soybeans. This work will expedite transgenic or marker-assisted genetic enhancement studies in crops for developing high-yielding stress-tolerant lines or varieties under abiotic stress.

“…From 2014-2018, soybeans, corn and oats have reached 100% emergence just before mid-June in Iowa (National Agricultural Statistics Service, 2019). Emergence is one of the earliest phases of the crop growth cycle, during which crops are extremely vulnerable to floods (Khosravi & Anderson, 1990;Nanjo et al, 2014;Tamang, Magliozzi, Maroof, & Fukao, 2014). Thus, running HAZUS-MH on June 9 th resulted in high agricultural damages because of crop growth cycle.…”
