“…The results were in accordance with several previous studies on legumes, Sesbania aegyptiaca and Sesbania grandiflora , Cassia siamea (Giri et al 2005), Pisum sativum cv. avola (Geneva et al 2006), Albizia saponaria (Tuheteru et al 2011a,b), P. mooniana (Husna et al , 2016, Sesbania cannabina (Ren et al 2016), and Cicer arietinum L. (Garg and Singla 2016). The existence of AMF may supply P for the formation of nodules as well as increase the activity of N 2 fixation by Rhizobium (Geneva et al 2006).…”

Abstract. Husna, Tuheteru FD, Wigati E. 2017. Short Communication: Growth response and dependency of endangered nedun tree species (Pericopsis mooniana) affected by indigenous Arbuscular Mycorrhizal Fungi inoculation. Nusantara Bioscience 9: 57-61. Arbuscular mycorrhizal fungi (AMF) were isolated from the rhizosphere of local nedun tree or kayu kuku (Pericopsis mooniana (Thw.) Thw.) and based on the results of previous studies which showed that inoculation with AMF mix enhanced growth and nutrient uptake of seedlings P. mooniana on ultisol and serpentine soil media. Thus study aimed to determine the effectiveness of indigenous AMF on the growth and dependence of P. mooniana. P. mooniana seedlings were grown on ultisol soil medium and inoculated with and without AMF (Clareodeglomus etunicatum, Glomus sp. (HA), Glomus sp. (KDI)) and mixed (C. etunicatum, Glomus sp. (HA), Glomus sp. (KDI) for 12 weeks under greenhouse conditions. The results showed that inoculation with Glomus sp. (HA) significantly increased plant height, stem diameter, number of leaves, dry weight (roots, shoots, total), nodulation, root length and leaf length. It was better than results on control of P. mooniana seedling but it was not significantly different from other types of AMF, except on Glomus sp. (HA) on plant height. The width of the leaf and shoot-root ratio was not influenced by the AMF. P. mooniana has a high dependency (<75%) with mycorrhizal dependency (MD) value ranging from 54-68%. Glomus sp. (HA) and other types of AMF have potential to be developed to support the conservation of P. mooniana.

“…Salt stress impacts plants by affecting germination, growth, reproduction, and the ability to biologically fix nitrogen [10]. Salinity affects vital physiological functions, hormonal regulation and nutritional balance [11,12], reduce carbon fixation [13], causes flower abortion, reduces flower numbers and pod setting, and eventually limits crop yield [14].…”

Globally, chickpea production is severely affected by salinity stress. Understanding the genetic basis for salinity tolerance is important to develop salinity tolerant chickpeas. A recombinant inbred line (RIL) population developed using parental lines ICCV 10 (salt-tolerant) and DCP 92-3 (salt-sensitive) was screened under field conditions to collect information on agronomy, yield components, and stress tolerance indices. Genotyping data generated using Axiom®CicerSNP array was used to construct a linkage map comprising 1856 SNP markers spanning a distance of 1106.3 cM across eight chickpea chromosomes. Extensive analysis of the phenotyping and genotyping data identified 28 quantitative trait loci (QTLs) explaining up to 28.40% of the phenotypic variance in the population. We identified QTL clusters on CaLG03 and CaLG06, each harboring major QTLs for yield and yield component traits under salinity stress. The main-effect QTLs identified in these two clusters were associated with key genes such as calcium-dependent protein kinases, histidine kinases, cation proton antiporter, and WRKY and MYB transcription factors, which are known to impart salinity stress tolerance in crop plants. Molecular markers/genes associated with these major QTLs, after validation, will be useful to undertake marker-assisted breeding for developing better varieties with salinity tolerance.

“…Interestingly, various microorganisms, including rhizobia, produce trehalose during their symbiotic or pathogenic interactions with plants (Brodmann et al, 2002; Foster et al, 2003; Ocón et al, 2007; Wilson et al, 2007, 2010; Nehls, 2008; Barraza et al, 2013; Garg and Singla, 2016). Free-living rhizobia under physiological stress produce high levels of trehalose and this metabolite plays an important role as osmoprotectant in the development of symbiotic nitrogen-fixing root nodules (Sugawara et al, 2010) or during nodule senescence (Müller et al, 2001).…”

The Class II Trehalose 6-phosphate Synthase Gene PvTPS9 Modulates Trehalose Metabolism in Phaseolus vulgaris Nodules

et al. 2016

Legumes form symbioses with rhizobia, producing nitrogen-fixing nodules on the roots of the plant host. The network of plant signaling pathways affecting carbon metabolism may determine the final number of nodules. The trehalose biosynthetic pathway regulates carbon metabolism and plays a fundamental role in plant growth and development, as well as in plant-microbe interactions. The expression of genes for trehalose synthesis during nodule development suggests that this metabolite may play a role in legume-rhizobia symbiosis. In this work, PvTPS9, which encodes a Class II trehalose-6-phosphate synthase (TPS) of common bean (Phaseolus vulgaris), was silenced by RNA interference in transgenic nodules. The silencing of PvTPS9 in root nodules resulted in a reduction of 85% (± 1%) of its transcript, which correlated with a 30% decrease in trehalose contents of transgenic nodules and in untransformed leaves. Composite transgenic plants with PvTPS9 silenced in the roots showed no changes in nodule number and nitrogen fixation, but a severe reduction in plant biomass and altered transcript profiles of all Class II TPS genes. Our data suggest that PvTPS9 plays a key role in modulating trehalose metabolism in the symbiotic nodule and, therefore, in the whole plant.
