Plant cell growth and morphogenesis depend on remodelling of both actin microtubule cytoskeletons. AtFH1 (At5g25500), the main housekeeping Arabidopsis formin, is targeted to membranes known nucleate bundle actin. The effect mutations in root development cytoskeletal dynamics was examined. Consistent with primarily actin-related formin function, fh1 mutants showed increased sensitivity polymerization inhibitor latrunculin B (LatB). LatB-treated had thicker, shorter roots than wild-type...
Small Rab GTPases are important regulators of vesicular trafficking in plants. AtRabA1d, a member the RabA1 subfamily small GTPases, was previously found vesicle-rich apical dome growing root hairs suggesting role during tip growth; however, its specific intracellular localization and plants has not been well described. The transient expression 35S::GFP:RabA1d construct Allium porrum Nicotiana benthamiana revealed structures, which were further corroborated stable transformed Arabidopsis...
Plant cell morphogenesis involves concerted rearrangements of microtubules and actin microfilaments. We previously reported that FH1, the main Arabidopsis thaliana housekeeping Class I membrane-anchored formin, contributes to dynamics microtubule stability in rhizodermis cells. Here we examine effects mutations affecting FH1 (At3g25500) on above-ground organ development seedlings, as well cytoskeletal organization dynamics, using a combination confocal variable angle epifluorescence...
Abstract The diversity in human diets that can be reached by proper use of different crops and varieties, including some underutilized ones, is a potentially powerful strategy to ensure food security prevent serious health problems caused current are often not fulfilling nutritional requirements. In the framework this research, content tocopherols tocotrienols, thiamine, riboflavin, pyridoxine, superoxide dismutase nine varieties quinoa, both colored nonpigmented, obtained from 4 countries,...
The cassava production system in Colombia is relevant for food security and agro-industrial development, especially the Caribbean region. To optimize this system, it necessary to understand technical socioeconomic particularities of crop, which facilitates cost improvements increased yields. Two main market segments are recognized country, human consumption industrial purposes (starch animal feed). There still no comprehensive study on characterization systems; therefore, work aims identify...
The ARP2/3 complex and formins are the only known plant actin nucleators. Besides their actin-related functions, both systems also modulate microtubule organization dynamics. Loss of main housekeeping Arabidopsis thaliana Class I membrane-targeted formin FH1 (At3g25500) is to increase cotyledon pavement cell lobing, while mutations affecting subunits exhibit an opposite effect. Here we examine role subunit ARPC5 (At4g01710) in epidermal morphogenesis with focus on cells trichomes using a...
Sweet potato is a crop with wide morpho-agronomic variation among genotypes. Source-sink relationship determined by the regulation capacity of heterotrophic and autotrophic organs. To understand influence morphological traits, biomass allocation, plant growth on sub-humid adaptation, eighteen genotypes were morpho-agronomically characterized under three texture soils (Cerete, Carmen de Bolivar, Corozal). Subsequently, selected evaluated to determine rates and, source demand potential....
The dynamic localization of endosomal compartments labeled with targeted fluorescent protein tags is routinely followed by time lapse fluorescence microscopy approaches and single particle tracking algorithms. In this way trajectories individual endosomes can be mapped linked to physiological processes as cell growth. However, other aspects behavior including interactions are difficult follow in manner. Therefore we characterized the properties early late throughout entire course root hair...
The genetic diversity of sweet potato [Ipomoea batatas (L.) Lam.] and its wild relatives has been collected conserved in germplasm collections worldwide explored employing several tools. characterization crops through morphological tools produce useful information. However, the use conventional descriptions exhibits limitations due to subjective categorical parameters that affect phenotypic description estimation. In order increase efficiency discriminate different phenotypes not detected by...
In Colombia, the highest cassava production comes from semi-arid region of Atlantic Coast with relatively low yield for fresh consumption (≤11 t/ha). Development improved varieties is based on a plant ideotype which integrates group desirable traits independently measured in field. However, selecting high performance genotypes several simultaneously complex process. Sixteen were evaluated under four environmental conditions (localities) Colombian Caribbean (Cereté, Carmen de Bolivar, Agustín...
Cassava (Manihot esculenta Crantz) is an important food security crop for many tropical and subtropical countries. It also acquiring increasing role in rural development as raw material different industries. The most industrial uses of cassava are a source energy the feed industry starch. To consolidate expand cassava, increased emphasis search value-added traits, while maintaining or enhancing its productivity, has recently been given by breeding project at CIAT. For industry, main...
Abstract Background Sweetpotato is an important staple food crop worldwide. The genotype mainly influences the nutritional quality of its storage roots, but environmental conditions could produce significant variations in chemical composition and quality. aim this study was to characterize sweetpotato diversity 20 selected genotypes identify harvest time (90, 120, 150 days after planting-DAP) effects on attributes estimated by proximate analysis (dry matter, ash, crude fiber, total protein,...
The deficiency of vitamin A is associated with preventable childhood infections and blindness. Optimal nutrition from a dietary variety selection nutrient-rich foods are needed to enrich the diet. Orange-fleshed sweet potato (OFSP) source provitamin due its bioavailability carotenes in roots that can be influenced by variety, environmental crop management conditions. aim was characterize six genotypes [yellow-fleshed (YFSP) OFSP] using high-throughput phenotyping approaches determine...
Abstract Sweet potato is a valuable staple crop that guarantees food security to large segment of the world population. The wide phenotypic and genetic variability this species an indication its high adaptation capacity diverse environmental conditions. In Colombia, it neglected underutilized crop, mainly managed by traditional knowledge. aim study was recognize contribution in situ conservation characterize habitats uses shed light on design their management strategies. Germplasm data...
Adaptation to several environmental conditions is a challenge for breeders producing new varieties. Breeders select genotypes which show higher performance according desired traits compared the average of large segregant population. In crops, selection index mainly based on such as yield, quality, adequate plant architecture, etc. Therefore, multi-trait allows identification that integrally exhibit better profile and stability, in addition dissection promising varieties their superiority an...
Sweet potato is a crop with wide capacity to adapt adverse conditions. To study the tolerance of sweet low-altitude environment, 34 genotypes comprising three groups from different altitude conditions ranging 18–599, 924–1298, 1401–2555 meters above sea level were evaluated. These evaluated through ecophysiological parameters: net photosintetic rate (Pn), stomatal conductance (GS), transpiration (E), leaf internal CO2 (ICO2), vapor pressure deficit (VPD) and temperate (LT). sSubsequently,...
Abstract Vegetative propagation of sweet potato lead to the accumulation diseases from generation generation, which represents a threat both productivity and conservation genetic resources. In vitro techniques can help overcome phytosanitary problems by applying plant material cleaning strategies. The objective this study was develop in micropropagation strategies for production high-quality an orange-fleshed variety recently released Colombia. Molecular identification contaminating...
Abstract Biofortified cassava ( Manihot esculenta ) plays a crucial role in enhancing the nutritional value of this essential staple, particularly regions with limited dietary diversity and prevalent deficiencies. The program at International Center Tropical Agriculture has dedicated over decade to increase β‐carotene content biofortified cassava, simultaneously focusing on improving yield, dry matter, plant architecture. This paper presents realized genetic gains by analyzing data from...
