“…It is estimated that biological nitrogen fixation (BNF) by legumes annually adds 40 million tons of N to soils (Herridge, Peoples, & Boddey, ). Peanut, like other legumes, improves the soil nitrogen status of soil due to its ability to obtain fixed nitrogen from bacterial symbiosis (Furlan, Bianucci, Castro, & Dietz, ; Graham & Vance, ). More specifically, peanut exhibits a substantial N 2 ‐fixation ability which is nearly 100 to 190 kg N/ha (Boddey, Urquiaga, Neves, Suhet, & Peres, ).…”

“…Abiotic stresses including drought, salinity and Fe‐unavailability interfere with the N 2 ‐fixation ability of peanut and other legumes. Water unavailability to peanut plants resulted in a significant reduction in N 2 ‐fixation, although its magnitude varied among cultivars (Furlan et al., ). Drought induced reduction in BNF is believed to be due to inadequate oxygen, water supply, carbon and nitrogen imbalance, and impairment of sucrose synthetase activity (Furlan et al., ; González, Gordon, James, & Arrese‐Igor, , ; Serraj, Bona, Purcell, & Sinclair, ).…”

Peanut is a multipurpose oil-seed legume, which offer benefits in many ways. Apart from the peanut plant's beneficial effects on soil quality, peanut seeds are nutritious and medicinally and economically important. In this review, insights into peanut origin and its domestication are provided. Peanut is rich in bioactive components, including phenolics, flavonoids, polyphenols, and resveratrol. In addition, the involvement of peanut in biological nitrogen fixation is highly significant. Recent reports regarding peanut responses and N 2 fixation ability in response to abiotic stresses, including drought, salinity, heat stress, and iron deficiency on calcareous soils, have been incorporated. As a biotechnological note, recent advances in the development of transgenic peanut plants are also highlighted. In this context, regulation of transcriptional factors and gene transfer for the development of stress-tolerant peanut genotypes are of prime importance. Above all, this review signifies the importance of peanut cultivation and human consumption in view of the scenario of changing world climate in order to maintain food security.

“…Stomatal activity is essential in physiological processes, being the main means of gaseous exchanges between the atmosphere and the interior of the photosynthetic machinery (Singh and Reddy, 2011). Furlan et al (2017) reported that a decrease in photosynthesis may restrict the supply of carbon to the nodules; this fact may explain the decrease in nodule weight in some of the genotypes investigated. A high similarity in the Ci, A and E was also observed, a fact expected because, as the water availability in the soil is reduced, the stomatal closure is induced, consequently there is a reduction in photosynthesis, limiting the entry of CO 2 , as well as a reduction in transpiration, because the main means of water loss is through the stomata (Larcher, 2006).…”

The peanut plant has high plasticity and great adaptability to adverse conditions, including drought. To mitigate the negative effects of drought on legumes, nitrogen-fixing microorganisms have been investigated in some plant species, such as soybeans and beans. We analyzed the role Bradyrhizobium strains in peanut genotypes subjected to water deficit by means of plant growth, physiological and gene expression analysis. The research was conducted under greenhouse conditions with the runner peanut genotypes (IAC Runner 886, 2012-33 and 2012-47) and two Bradyrhizobium strains (ESA 123 and SEMIA 6144). After 20 days of germination, the water supply was completely interrupted and gas exchange analysis were carried out using an infrared gas analyzer, up to the 10 th day of stress. Leaves were collected for the analysis of proline content and the expression of NCED and ERF8 genes. Analyses of plant height (PH), shoot dry mass (SDM), root dry mass (RDM), number of nodules (NN) and nodule weight (NW) also were ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 18 (4): gmr18379 S.L. Brito et al. 2 performed. The peanut shoots inoculated with the Bradyrhizobium strains obtained the best results. The genotypes inoculated with the ESA 123 strain obtained superior responses compared to the nonstressed treatment inoculated with the same bacteria and the stressed control without bacterial inoculation. In the ESA 123 inoculated treatments, the water stressed plants had higher RDM (28.5% higher, on average), NN (two fold higher), and gene expression (approximately six and threefold higher for ERF8 and NCED genes, respectively). The increase in the expression of NCED and ERF8 genes, in the three genotypes inoculated with ESA 123, suggests a key role of this inoculant in the activation of metabolic cascades for plant protection under water deficit.

“…Peanuts have the ability to form root nodules and anchor N in the air due to symbiosis with Rhizobium (Suryantini, 2015). Furlan et al (2017) added that root nodules protect peanuts from drought stress so that nutrient absorption in the soil remains good. This is in line with the data on the number of root nodules (Table 4), where phosphorus is needed for maximum root nodule formation.…”

Soil is an important factor in peanut cultivation as a nutrient provider. In recent years, peanut production has dwindled due to the decrease in soil fertility. Boron as a micronutrient can maximize peanut production through optimum viability of flowers and phosphor as essential nutrients for peanut to improve its pod filling. This study aims to examine the application of boron and phosphor growth and formation of peanut gynophore. The research was conducted from September 2017 to January 2018 in Sambirembe village, Magetan. The experiment uses randomized complete block design (RCBD) with the first factor applied on the dose of boron fertilizer (0, 1, 2 3 kg ha-1) and the second was on the dose of phosphor fertilizer (0, 75, 100, 150 kg ha-1), repeated 3 times. Boron application resulted in the highest plant height at the fourth week by 10.45%. The application of 1 kg ha-1 boron without phosphorus (0 kg ha-1) yielded the highest gynophore formation, i.e. 42.
