“…This approach has identified several differentially expressed genes (Almeida et al 2015), opening the way to a powerful route of identification of candidate resistance genes and more detailed study of resistance gene networks in L. sativus (Vaz Patto and Rubiales 2014).…”

The field of plant breeding covers a broad range of different species and categories of plants. While there are many techniques and issues that are similar across these species, many more are unique to each genus.The Handbook of Plant Breeding is organized by major crop categories and includes the most up-to-date molecular techniques being used. It will serve as a resource for plant breeding laboratories in both the university and industrial setting.More information about this series at

“…For instance, Spd and /Spm synthase activities were also up-regulated in soybean against the cyst nematode Heterodera glycines (Wan et al, 2015); SAMDC and ADC transcripts were downregulated, and the PAO gene family was upregulated in response to the Asian soybean rust Phakopsora pachyrhizi Sydow (Panthee et al, 2009). In turn, downregulation of ODC and Spm synthase were reported in L. sativus in response to A. lathyri (Almeida et al, 2015) and in the M. truncatula-Phymatotrichopsis omnivore interaction (Uppalapati et al, 2009), respectively.…”

Polyamines (PAs) are natural aliphatic amines involved in many physiological processes in almost all living organisms, including responses to abiotic stresses and microbial interactions. This review presents the profuse evidence that relates changes in polyamines levels during responses to biotic and abiotic stresses in model and cultivable species within Leguminosae, and examines their potential roles in the functioning of symbiotic interactions with nitrogen fixing bacteria and arbuscular mycorrhizae. The family Leguminosae constitutes an economically and ecologically key botanical group for humans, being also regarded as the most important protein source for livestock. The ability of legumes to establish symbiotic interactions with nitrogen fixing bacteria and arbuscular mycorrhizae fungi, gives to some legume species that are able to exploit their molecular machinery “pioneer” attributes, with better competition in nutrient-poor soils and higher adaptation to restricted environments. However, many legume crops may be affected by climate change-derived environmental stresses, whereby maintaining their yields safe from adverse environmental conditions is probably one of the biggest challenge facing modern agriculture. Therefore, the obtaining of vigorous genotypes with higher tolerance to abiotic and biotic stressors has turned an increasingly important biotechnological target. At this scenario, PAs can play an important role, and genetic manipulation of crop plants with genes encoding polyamine PA biosynthetic pathway enzymes is envisioned as a strategy to achieve plants with improved stress tolerance and symbiotic performance. As linking plant physiological behavior with "big data" available in "omics" is an essential step to improve our understanding of legumes responses to global change, we also examined integrative MultiOmics approaches available to decrypt the interface legumes-PAs-abiotic and biotic stress or interactions. These approaches are expected to accelerate the identification of stress tolerant phenotypes and the design of new biotechnological strategies to increase their yield and adaptation to marginal environments, making a better use of available plant genetic resources.

“…Grass pea ( Lathyrus sativus L.) belonging to the family Fabaceae is known for its remarkable ability to tolerate a wide range of biotic and abiotic stresses . The present study is designed to explore potentialities of Lathyrus sativus L.‐efficient and resistant PGPR symbioses as biological solution for improving the efficiency and Pb contaminated soils phytoremediation.…”

Effect of Pb‐resistant plant growth‐promoting rhizobacteria inoculation on growth and lead uptake by Lathyrus sativus

et al. 2018

In search of efficient and resistant plant growth-promoting rhizobacteria (PGPR) strains with multiple activities, a total of twelve bacterial belonging to R. leguminosarum, S. meliloti, Pseudomonas sp., P. fluorescens, Luteibacter sp., Variovorax sp., B. simplex, and B. megaterium were isolated from root nodules of grass pea (Lathyrus sativus L.) grown in contaminated soils. Upon screening, all test strains were able to synthesize indoleacetic acid; more than 90% were siderophore producers and 75% showed varying levels of phosphate solubilizing ability. The gaseous metabolite biosynthesis showed that 42% of strains were cyanogenic. The lead (Pb) bioaccumulation differs with incubation times between cell wall and cytoplasm. Indeed, the most part of Pb was adsorbed to cell surface. A pot experiment was conducted for investigating the capability of combined bacteria to promote plant growth of Lathyrus sativus under controlled conditions. Subsequently, the performance of symbiosis Lathyrus sativus-PGPR (I4: R. leguminosarum (M5) + B. simplex + Luteibacter sp. + Variovorax sp.) was investigated under lead stress using hydroponic culture to elucidate the effect of bacterial inoculation on Pb uptake as well as plant growth. Results showed that under 0.5 mM Pb, inoculation with I4 significantly increased shoots and roots biomass by 59% and 56%, respectively, and improved Pb uptake in both shoots and roots by 39% and 47%, respectively, as compared to uninoculated plants. The inoculation of Lathyrus sativus with efficient and Pb resistant PGPR is a promising symbiosis that having significant potential to improve phytoremediation of Pb-polluted soils.
