“…Leaf bronzing (LB) is one of the key symptoms appearing at the vegetative stage and it is associated with various morpho-physiological traits, such as shoot and root length, number of tillers and panicles, shoot and root dry weight, a modification in root architecture system (RAS)-attributed traits, days to flowering, grain yield reduction, chlorophyll content, enzyme activity, ethylene production, non-structural carbohydrates, photosynthesis activity, formation of Fe plaque, and aerenchyma that is majorly involved in Fe toxicity tolerance [ 2 , 13 , 58 , 62 , 83 , 84 , 85 , 86 ]. The high concentration of carbonates, phosphates, and nitrates in either hydroponics or the soil makes Fe unavailable to plants due to increased pH [ 52 , 87 , 88 , 89 ].…”

Iron (Fe) deficiency and toxicity are the most widely prevalent soil-related micronutrient disorders in rice (Oryza sativa L.). Progress in rice cultivars with improved tolerance has been hampered by a poor understanding of Fe availability in the soil, the transportation mechanism, and associated genetic factors for the tolerance of Fe toxicity soil (FTS) or Fe deficiency soil (FDS) conditions. In the past, through conventional breeding approaches, rice varieties were developed especially suitable for low- and high-pH soils, which indirectly helped the varieties to tolerate FTS and FDS conditions. Rice-Fe interactions in the external environment of soil, internal homeostasis, and transportation have been studied extensively in the past few decades. However, the molecular and physiological mechanisms of Fe uptake and transport need to be characterized in response to the tolerance of morpho-physiological traits under Fe-toxic and -deficient soil conditions, and these traits need to be well integrated into breeding programs. A deeper understanding of the several factors that influence Fe absorption, uptake, and transport from soil to root and above-ground organs under FDS and FTS is needed to develop tolerant rice cultivars with improved grain yield. Therefore, the objective of this review paper is to congregate the different phenotypic screening methodologies for prospecting tolerant rice varieties and their responsible genetic traits, and Fe homeostasis related to all the known quantitative trait loci (QTLs), genes, and transporters, which could offer enormous information to rice breeders and biotechnologists to develop rice cultivars tolerant of Fe toxicity or deficiency. The mechanism of Fe regulation and transport from soil to grain needs to be understood in a systematic manner along with the cascade of metabolomics steps that are involved in the development of rice varieties tolerant of FTS and FDS. Therefore, the integration of breeding with advanced genome sequencing and omics technologies allows for the fine-tuning of tolerant genotypes on the basis of molecular genetics, and the further identification of novel genes and transporters that are related to Fe regulation from FTS and FDS conditions is incredibly important to achieve further success in this aspect.

“…In the environmental stress conditions, epistasis genes can be more involved, specifically in initiating resistance mechanisms (Hansen 2013). Epistasis gene action plays an important role in plant adaptation to abiotic stresses such as Al stress (Sihaloho et al 2105) and Fe (Nugraha et al 2016), as well as high-temperature stress caused by differences in altitude. In Indonesia, tomatoes are generally cultivated in the highlands with a daily temperature range of 16-30°C to achieve high production.…”

Abstract. Mawasid FP, Syukur M, Trikoesoemaningtyas. 2019. Epistatic gene control on the yield of tomato at medium elevation in the tropical agroecosystem. Biodiversitas 20: 1880-1886. Cultivation of tomatoes on the middle-low plain generally decreases the quantity and quality of the yield due to high-temperature stress. Increasing the size and weight of lowland tomatoes is needed to enhance national production. Information on the action and genetic model of target characters is needed in the preparation of the assembly program, especially for selection needs. This study aims to obtain genetic information and heritability of tomato yield characters, as a basis for assembling large tomato varieties for the lowlands. The study was conducted using six populations (P1, P2, F1, BCP1, BCP2, and F2) resulting from two different crosses of 99D x Tora (C-I) and 97D x Tora (C-II). The results show that the action of non-additive genes and non-allelic interactions has a large value, with duplicate epistasis being more dominant than complementary epistasis. Duplicate epistasis was found in the character of harvest time, fruit length, fruit diameter, fruit weight in cross I and flowering time, harvest time, fruit length, fruit diameter, and number of fruits in cross II, while complementary epistasis was found in flowering time, fruit weight per plant, number of fruits in cross I, and fruit weight, fruit weight per plant in cross II. Moderate to high heritability was found in the character of fruit length, fruit diameter, fruit weight, and fruit weight per plant. The values are higher in population from the cross I (99D x Tora) for each character, indicating that the cross I has a higher potential for genetic progress than cross II. Selection is recommended when the homozygosity has increased, using the Bulk method or Single Seed Decent. The two methods above can maintain variability in the next generation, so epistasis genes that control target characters are not drastically eliminated.

“…But after 42 DAT the bronzing scored changed, became more tolerant probably due to oxidation of ferrous ion. Oxidation of iron is main problem to be consider for doing experimental on iron toxicity rice in the green house conditions (Elec et al 2013;Nugraha et al 2016).…”

“…These free radicals are responsible for the damage due to the iron toxicity (Oliveira et al 2013). The visual symptom of iron toxicity is the "bronzing" of leaves, that affects the physiological process as well as the grain yield of rice (Audebert and Fofana 2009;Sahrawat 2004;Nugraha et al 2016).…”

“…However, the hydroponic culture is also limited by the duration of media culture which is needed to be refreshed with new media and it is also very vulnerable to the change of pH, oxidation, and precipitation of iron (Suhartini and Makarim 2009). Hydroponic method is suitable for initial screening to identify robust rice tolerance to iron toxicity in seedling stage (Nugraha et al 2016). On the other hand, information on identification of rice genotype at the whole growth stages under ex-situ condition (green house) is still limited.…”

<p>Iron toxicity affects the growth and yield of rice plant. Overcoming the damage of rice production by iron toxicity requires furthermore researches from laboratory to field levels. Here, we study responses of rice genotypes to iron toxicity between vegetative stage in hydroponic and whole grow stages in the pot. The first experiment was hydroponic experiment using twelve rice genotypes which were growth in the Yoshida Solution with addition of 0.2 % of agar. Three level of iron was given at 0, 500 and 700 ppm. The second experiment was the pot experiment using alluvial soil added with 3.000 ppm of ferrous combine with four levels of potassium and the control on Cilamaya Muncul (tolerant), Inpara 8 (moderate tolerant) and IR 64 (susceptible). In hydroponic experiment, even though the symptom appeared obviously, the leaf bronzing score (LBS) of tolerant and sensitive genotypes were not different. Physiological traits were significantly affected by Fe treatment in all varieties. Then symptom and physiological traits were significantly correlated. Through the pot experiment, it was confirmed the tolerance of each varieties. However, we couldn’t see the correlation between the LBS on hydroponic and soil at this time. And the heading delay was new finding, but it depended on varieties. We also could see the possibility of potassium application to inhibit iron toxicity but still we need to explore how it works. <br />Kata kunci: iron toxicity, rice, hydroponic, soil</p>
