Pheromone‐binding proteins based phylogenetics and phylogeography of Maruca spp. from Asia, Africa, Oceania, and South America

open access: yesEcology and Evolution, Volume 9, Issue 16, Page 9239-9272, August 2019., 2019
High pairwise FST values (0.41–0.73) and phylogenetic analyses distinguished the putative Maruca species in South America from those occurring in rest of the world, and possibly two putative sub‐species in Asia and Africa. The negative Tajima's D and Fu's FS values showed the recent demographic expansion of Maruca populations Abstract Variations in the

Knockout of an Azorhizobial dTDP-L-Rhamnose Synthase Affects Lipopolysaccharide and Extracellular Polysaccharide Production and Disables Symbiosis with Sesbania rostrata

open access: yesMolecular Plant-Microbe Interactions, 2001
A nonpolar mutation was made in the oac2 gene of Azorhizobium caulinodans. oac2 is an ortholog of the Salmonella typhimurium rfbD gene that encodes a dTDP-L-rhamnose synthase. The knockout of oac2 changed the lipopolysaccharide (LPS) pattern and affected

Pest categorisation of Hirschmanniella spp.

open access: yesEFSA Journal, Volume 16, Issue 6, June 2018., 2018
Abstract The Panel on Plant Health performed a pest categorisation of nematodes belonging to the genus Hirschmanniella (Nematoda: Pratylenchidae). Twenty‐nine species in this genus have been considered of which five species are present in the EU (Hirschmanniella behningi, Hirschmanniella gracilis, Hirschmanniella halophila, Hirschmanniella loofi and ...

An Insight in the Reproductive Biology of Therophilus javanus (Hymenoptera, Braconidae, and Agathidinae), a Potential Biological Control Agent against the Legume Pod Borer (Lepidoptera, Crambidae)

open access: yesPsyche: A Journal of Entomology, Volume 2017, Issue 1, 2017., 2017
Therophilus javanus is a koinobiont, solitary larval endoparasitoid currently being considered as a biological control agent against the pod borer Maruca vitrata, a devastating cowpea pest causing 20–80% crop losses in West Africa. We investigated ovary morphology and anatomy, oogenesis, potential fecundity, and egg load in T.

Bacterial‐induced calcium oscillations are common to nitrogen‐fixing associations of nodulating legumes and non‐legumes

open access: yesNew Phytologist, Volume 207, Issue 3, Page 551-558, August 2015., 2015
Summary Plants that form root‐nodule symbioses are within a monophyletic ‘nitrogen‐fixing’ clade and associated signalling processes are shared with the arbuscular mycorrhizal symbiosis. Central to symbiotic signalling are nuclear‐associated oscillations in calcium ions (Ca2+), occurring in the root hairs of several legume species in response to the ...

Nod Factor Perception During Infection Thread Growth Fine-Tunes Nodulation

open access: yesMolecular Plant-Microbe Interactions, 2007
Bacterial nodulation factors (NFs) are essential signaling molecules for the initiation of a nitrogen-fixing symbiosis in legumes. NFs are perceived by the plant and trigger both local and distant responses, such as curling of root hairs and cortical ...

Root Distribution and Nitrogen Fixation Activity of Tropical Forage Legume American Jointvetch (Aeschynomene americana L.) cv. Glenn under Waterlogging Conditions

open access: yesInternational Journal of Agronomy, Volume 2014, Issue 1, 2014., 2014
We investigated the root distribution and nitrogen fixation activity of American jointvetch (Aeschynomene americana L.) cv. Glenn, under waterlogging treatment. The plants were grown in pots under three different treatments: no waterlogging (control), 30 days of waterlogging (experiment 1), and 40 days of waterlogging (experiment 2).
