Microscopic pores present in the epidermis of plant aerial organs, called stomata, allow gas exchanges between inner photosynthetic tissue and atmosphere. Regulation stomatal aperture, preventing excess transpirational vapor loss, relies on turgor changes two highly differentiated epidermal cells surrounding pore, guard cells. Increased cell due to increased solute accumulation results opening, whereas decreased closing. Here we provide direct evidence, based reverse genetics approaches,...
Sexual reproduction in plants requires elongation of the pollen tube through transmitting tissues toward ovary. Tube growth rate is a major determinant competitive ability. We report that K + channel Shaker family Arabidopsis , SPIK, plays an important role development. SPIK was found to be specifically expressed pollen. When heterologously COS cells, its product formed hyperpolarization-activated channels. Disruption (T-DNA insertion) coding sequence strongly affected inwardly rectifying...
The AKT2 K(+) channel is endowed with unique functional properties, being the only weak inward rectifier characterized to date in Arabidopsis. gene expressed widely, mainly phloem but also at lower levels leaf epiderm, mesophyll, and guard cells. mRNA level upregulated by abscisic acid. By screening a two-hybrid cDNA library, we isolated protein phosphatase 2C (AtPP2CA) involved acid signaling as putative partner of AKT2. We further confirmed interaction vitro binding studies. expression...
The success of current control tools in combatting malaria vectors is well established. However, sustained residual transmission Plasmodium parasites persists. Mass drug administration (MDA) to humans the endectocide ivermectin for vector receiving increasing attention. feeding upon animals escape this promising approach. Zoophagy mosquitoes sustains both population and endemic vector-borne pathogens. Therefore, only a strategy that will combine MDAs targeted at their peridomestic could be...
Background Twenty-seven villages were selected in southwest Burkina Faso to implement new vector control strategies addition long lasting insecticidal nets (LLINs) through a Randomized Controlled Trial (RCT). We conducted entomological surveys the during dry cold season (January 2017), hot (March 2017) and rainy (June describe malaria vectors bionomics, insecticide resistance transmission prior this trial. Methods carried out hourly catches (from 17:00 09:00) inside outside 4 houses each...
Abstract Stomata optimize land plants’ photosynthetic requirements and limit water vapor loss. So far, all of the molecular electrical components identified as regulating stomatal aperture are produced, operate, directly within guard cells. However, a completely autonomous function cells is inconsistent with anatomical biophysical observations hinting at mechanical contributions epidermal origins. Here, potassium (K+) assays, membrane potential measurements, microindentation, plasmolysis...
Abstract Malaria remains an enduring challenge in sub-Saharan Africa, affecting public health and development. Control measures can include the use of insecticides that target adult Anopheles mosquitoes transmitting malaria-causing Plasmodium parasite. Such also bite livestock, allowing vector populations to be maintained at levels enable parasite transmission. Thus, one way control spread malaria includes endectocide-treated livestock which renders blood cattle toxic such mosquito...
Abstract Aim To investigate the phylogeographical structure of Guinea multimammate mouse, Mastomys erythroleucus (Temminck, 1853), a widespread murid rodent in sub‐Saharan (Sahel and Sudan) savannas, for better understanding impacts geographical historical factors on evolutionary history this species, context growing database studies African savanna mammal species. Location Sahel Sudan Africa. Methods We sequenced whole cytochrome b gene 211 individuals from 59 localities distributed Senegal...
Abstract Background Domesticated animals play a role in maintaining residual transmission of Plasmodium parasites humans, by offering alternative blood meal sources for malaria vectors to survive on. However, the treated with veterinary formulations anti-helminthic drug ivermectin can have an insecticidal effect on adult vector mosquitoes. This study therefore assessed effects treating cattle long-acting injectable survival important species, determine whether it has potential as...
A speciation process is ongoing in the primary vector of malaria Africa, Anopheles gambiae. Assortatively mating incipient species known as M and S forms differentially exploit larval breeding sites associated with different ecological settings. However, some gene flow between limits significant genomic differentiation mainly to small centromere-proximal regions on chromosomes X 2L, termed 'speciation islands' expectation that they contain genes responsible for reproductive isolation. As...
We present a new and innovative identification method based on deep learning of the wing interferential patterns carried by mosquitoes Anopheles genus to classify assign 20 species, including 13 malaria vectors. provide additional evidence that this approach can identify spp. with an accuracy up 100% for ten out species. Although, was moderate (> 65%) or weak (50%) three seven The process discriminate cryptic sibling species is also assessed belonging Gambiae complex. Strikingly, An....
Reduction in malaria clinical cases is strongly dependent on the ability to prevent Anopheles infectious bites. Vector control strategies using long-lasting insecticidal nets and indoor residual spraying with insecticides have contributed significantly reduce incidence of many endemic countries, especially Sub-Saharan region. However, global progress reducing has plateaued since 2015 mostly due increased insecticide resistance behavioral changes vectors. Additional are thus required further...
Characterizing the entomological profile of malaria transmission at fine spatiotemporal scales is essential for developing and implementing effective vector control strategies. Here, we present a fine-grained dataset
Abstract The multimammate rat Mastomys huberti is a Sahelian species restricted to West Africa. Throughout its distribution area, the associated with humid habitats, flood plains and ponds, which make current highly fragmented. Knowing that dry climatic phases regularly alternated along Quaternary in Africa, it can be postulated evolutionary history of genetic variation largely reflect these oscillations. We used mitochondrial cytochrome b sequences investigate phylogenetic relationships M....
Human and Animal Trypanosomes are major problems for the socio-economic growth of developing countries like Burkina Faso. Ivermectin is currently used to treat humans in mass drug administration programs Africa, also commonly veterinary purposes. In this study, we tested effect ivermectin injected into cattle on survival fecundity Glossina palpalis gambiensis, main vector human animal trypanosomes West Africa.Three cows (local zebu*baoulé crossbreds) were used, received either no (for...
Abstract Background The direct membrane feeding assay (DMFA), whereby gametocyte-infected blood is collected from human donors and which mosquitoes feed through a membrane, proving essential for assessing parameters influencing Plasmodium transmission potential in endemic countries. success of DMFAs closely tied to gametocyte density the blood, with relatively high gametocytaemia ensuring optimal infection levels mosquitoes. As intensity declines control efforts, occurrence asymptomatic...
In West Africa, M and S molecular forms of Anopheles gambiae sensu stricto (Diptera: Culicidae) Giles, frequently occur together, although with different population bionomics. The form typically breeds in rain‐dependant water collections is present during the rainy season only whereas can thrive all year long areas permanent breeding opportunities. study, we explored physiological developmental trade‐offs at play laboratory colonies field populations that originated from an area sympatry...
This study explored the metabolic adjustments prompted by a switch between rainy and dry season conditions in African malaria mosquitoes Anopheles gambiae (M S molecular forms) arabiensis. Mosquitoes were reared contrasted experimental reflecting environmental variation Burkina Faso. Thirty-five metabolites (including sugars, polyols, amino acids) monitored newly emerged males females, their ecdysteroid titers determined. Metabolomic signatures remarkably similar across species, when...
