“…The inducement of various plant growth regulators such as auxins, cytokinins, and gibberellins during root mycorrhizal colonization has been reported (Martín-Rodríguez et al, 2016). In addition, the enhancement of plant photosynthesis, cell metabolism, and water and nutrient acquisition by AMF symbiosis has been also reported (Iqbal et al, 2021), which is in agreement with our results on the enhancement of the photosynthetic pigments and nutrient contents in banana plantlets by mycorrhizal colonization.…”

“…This is due to the enhancing effect of AMF on nutrients uptake via their extraradical mycelium network, which explores larger soil areas. Moreover, AMF produces organic acids and enzymes such as phosphatases in the soil, which facilitate the nutrients released from the soil, and enhance their availability to the plant (Saia et al, 2014;Iqbal et al, 2021). Furthermore, the mycorrhizal colonization of the banana plantlets alleviated the adverse effects due to the infection and/or salinity stresses, compensated for the nutrient deficiency due to both stresses, and maintained the ionic homeostasis, which led to the enhancing effect on the banana growth.…”

Effects of Mycorrhizal Colonization on Transcriptional Expression of the Responsive Factor JERF3 and Stress-Responsive Genes in Banana Plantlets in Response to Combined Biotic and Abiotic Stresses

et al. 2021

Banana plants (Musa acuminata L.) are exposed to various biotic and abiotic stresses that affect their production worldwide. Banana plants respond to these stresses, but their responses to combined stresses are unique and differ from those to various individual stresses. This study reported the effects of the mycorrhizal colonization of banana roots and/or infection with root rot on the transcriptional expression of the responsive factor JERF3 and stress-responsive genes (POD, PR1, CHI, and GLU) under different salinity levels. Different transcriptional levels were recorded in response to the individual, dual, or triple treatments. All the applied biotic and abiotic stresses triggered the transcriptional expression of the tested genes when individually applied, but they showed different influences varying from synergistic to antagonistic when applied in combinations. The salinity stress had the strongest effect when applied in combination with the biotic stress and/or mycorrhizal colonization, especially at high concentrations. Moreover, the salinity level differentially affects the banana responses under combined stresses and/or mycorrhizal colonization in addition, the mycorrhizal colonization of banana plantlets improved their growth, photosynthesis, and nutrient uptake, as well as greatly alleviated the detrimental effects of salt and infection stresses. In general, the obtained results indicated that the responses of banana plantlets under the combined stresses are more complicated and differed from those under the individual stresses depending on the crosstalks between the signaling pathways.

“…LOC_Os02g03150 (AM3), LOC_Os02g03190 (AM31), and LOC_Os02g03410 (AM24) (Gutjahr et al, 2008) in the dry season and LOC_Os03g10620 (DI4) (Takeuchi et al, 2018), LOC_Os07g22710 (OsCPK18) (Campos-Soriano et al, 2011), and LOC_Os10g18510 (AM34) (Gutjahr et al, 2008) in wet season. The aerobic conditions maintained in this study must have supported the growth of soil microbes including mycorrhiza via root exudates (Iqbal et al, 2021). This can be considered as one of the reasons for the difference in root dry weight in the anaerobic wet season where the mycorrhizal activity is delimited and the aerobic dry condition in the dry season.…”

Superior Haplotypes for Early Root Vigor Traits in Rice Under Dry Direct Seeded Low Nitrogen Condition Through Genome Wide Association Mapping

et al. 2022

Water and land resources have been aggressively exploited in the recent decades to meet the growing demands for food. The changing climate has prompted rice scientists and farmers of the tropics and subtropics to adopt the direct seeded rice (DSR) system. DSR system of rice cultivation significantly reduces freshwater consumption and labor requirements, while increasing system productivity, resource use efficiency, and reducing greenhouse gas emissions. Early root vigor is an essential trait required in an ideal DSR system of rice cultivation to ensure a good crop stand, adequate uptake of water, nutrients and compete with weeds. The aus subpopulation which is adapted for DSR was evaluated to understand the biology of early root growth under limited nitrogen conditions over two seasons under two-time points (14 and 28 days). The correlation study identified a positive association between shoot dry weight and root dry weight. The genome-wide association study was conducted on root traits of 14 and 28 days with 2 million single-nucleotide polymorphisms (SNPs) using an efficient mixed model. QTLs over a significant threshold of p < 0.0001 and a 10% false discovery rate were selected to identify genes involved in root growth related to root architecture and nutrient acquisition from 97 QTLs. Candidate genes under these QTLs were explored. On chromosome 4, around 30 Mbp are two important peptide transporters (PTR5 and PTR6) involved in mobilizing nitrogen in the root during the early vegetative stage. In addition, several P transporters and expansin genes with superior haplotypes are discussed. A novel QTL from 21.12 to 21.46 Mb on chromosome 7 with two linkage disequilibrium (LD) blocks governing root length at 14 days were identified. The QTLs/candidate genes with superior haplotype for early root vigor reported here could be explored further to develop genotypes for DSR conditions.

“…In contrast to this research study, Martín-Alonso, Llerena, and Acosta (2018) reported that combining bovine manure and AMF increased P absorption because of an improvement in nutrient retention and exchange capacity. AMF inoculation increased N, P, Ca and Mg, contents in root shoot aerial biomass (Iqbal, Ahmed, Isik, Sultana, and Ortaş, 2021); in basil plants, with Glomus species and plant growthpromoting rhizobacteria (PGPR) P content increased (Khalediyan, Weisany, and Schenk, 2021); P and K increased in roots compared with sprouts in plants inoculated with AMF (Bi et al, 2021).…”

Arbuscular mycorrhizal fungus and organics substrates effect on bean plant morphology and minerals

et al. 2022

View full text Add to dashboard Cite

Arbuscular mycorrhizal fungi (AMF) are obligate symbionts that require a host plant (tramp) and support (substrates) to be applied as bio-fertilizers in agriculture. The objective of this study is to assess eight native AMF consortia of semi-arid zones (C1-ART, C2-GEC, C3-PAR, C4-VIE, C5-CUC, C6-SAC, C7-SAB, and C8-MUZ) and their reproduction response in three organic substrates: coffee pulp (CP), bovine manure (BM) and sugarcane bagasse (SB) on bean Phaseolus vulgaris. Plant height, stem diameter, number of leaves, root length, fresh and dry biomass, and mineral content in root were measured. The organic substrates (CP and BM) and C5-CUC and C8-MUZ consortia increased plant height, root length, and total fresh and dry biomass considerably. After day 75 of inoculation, root colonization oscillated from 5.7% in C8-MUZ to 46.1% in C2-GEC and C4-VIE; the greatest number of spores (201) was obtained in CP substrate in a 100-g sample. N, P, K, Ca, Mg, Fe, Zn, Cu, and Mn contents in root and leaves were signif icantly high (P ≤ 0.001). To conclude, native AMF inoculation and substrates had positive effects on biomass content and nutrient levels in leaf and root with the C2-GEC and C3-PAR consortia and CP and BM substrates, which produced better effects in beans, making them a biofertilization alternative in agricultural crops.
