Dataset on biodiversity and agronomic performance of lentil and chickpea field trials in the Mediterranean Region.

Pulse crops have become more important in food production and consumption systems for the transition towards sustainability. We present an agroecological dataset from 304 samples from 12 legume field trials in five locations across three countries in the Mediterranean. The field trials were established in the seasons 2021/22 and 2022/23 and tested different lentil or chickpea cultivars, inoculants, intercropping and weeding regimes.

Sinorhizobium fredii HH103 nolR and nodD2 mutants gain capacity for infection thread invasion of Lotus japonicus Gifu and Lotus burttii.

Sinorhizobium fredii HH103 Rif , a broad-host-range rhizobial strain, forms ineffective nodules with Lotus japonicus but induces nitrogen-fixing nodules in Lotus burttii roots that are infected by intercellular entry. Here we show that HH103 Rif nolR or nodD2 mutants gain the ability to induce infection thread formation and to form nitrogen-fixing nodules in L. japonicus Gifu.

Sinorhizobium fredii HH103 Invades Lotus burttii by Crack Entry in a Nod Factor-and Surface Polysaccharide-Dependent Manner.

Sinorhizobium fredii HH103-Rif, a broad host range rhizobial strain, induces nitrogen-fixing nodules in Lotus burttii but ineffective nodules in L. japonicus. Confocal microscopy studies showed that Mesorhizobium loti MAFF303099 and S.

NolR regulates diverse symbiotic signals of Sinorhizobium fredii HH103.

We have investigated in Sinorhizobium fredii HH103-1 (=HH103 Str(r)) the influence of the nolR gene on the production of three different bacterial symbiotic signals: Nod factors, signal responsive (SR) proteins, and exopolysaccharide (EPS). The presence of multiple copies of nolR (in plasmid pMUS675) repressed the transcription of all the flavonoid-inducible genes analyzed: nodA, nodD1, nolO, nolX, noeL, rhcJ, hesB, and y4pF. Inactivation of nolR (mutant SVQ517) or its overexpression (presence of pMUS675) altered the amount of Nod factors detected.
