Global climate change will noticeably affect plant vegetative and reproductive development. The recent increase in temperatures has already impacted yields composition of berries many grapevine-growing regions. Physiological processes underlying temperature response tolerance the grapevine fruit have not been extensively investigated. To date, all studies investigating molecular regulation fleshly to abiotic stress were only conducted during day, overlooking possible critical night-specific...
The increasing temperature associated with climate change impacts grapevine phenology and development critical effects on grape yield composition. Plant breeding has the potential to deliver new cultivars stable quality under warmer conditions, but this requires identification of genetic determinants. This study tested potentialities microvine boost genetics in grapevine. A mapping population 129 microvines derived from Picovine x Ugni Blanc flb, was genotyped Illumina® 18 K SNP (Single...
Diurnal changes in gene expression occur all living organisms and have been studied on model plants such as Arabidopsis thaliana. To our knowledge the impact of nycthemeral cycle genetic program fleshly fruit development has hitherto overlooked. In order to circumvent environmental throughout development, young ripening berries were sampled simultaneously continuously flowering microvines acclimated controlled circadian light temperature changes. Gene profiles along monitored during both day...
Aim: In the long term, genetic improvement is one of major strategies to support sustainable wine production in a changing climate. Over past 5 years, we have developed an interdisciplinary research program that aimed to: i) characterize impact temperature increase sensed by entire plant or individual bunches on development and functioning plant, ii) identify physiological molecular mechanisms regulating response vegetative reproductive heat stress iii) develop tools map quantitative trait...
Improving crop water use efficiency, the amount of carbon assimilated as biomass per unit used by a plant, is major importance for agriculture becomes scarcer. In rice, genetic bases transpiration derivation efficiency at whole-plant scale, and its putative component trait restriction under high evaporative demand remain unknown. These traits were measured in 2019 panel 147 African rice (Oryza glaberrima) genotypes known to be potential sources tolerance genes biotic abiotic stresses. Our...
Crop wild relatives, the closely related species of crops, may harbour potentially important sources new allelic diversity for (a)biotic tolerance or resistance. However, to date, is only poorly characterized and evaluated. Banana has a large but narrow proportion currently used in breeding programmes. The main objective this study was evaluate genotype-dependent transpiration responses relation environment. By applying continuous high-throughput phenotyping, we were able construct...
Acclimation to water deficit (WD) enables plants maintain growth under unfavorable environmental conditions, although the mechanisms are not completely understood. In this study, natural variation of long-term acclimation moderate and severe soil WD was investigated in 18 Arabidopsis (Arabidopsis thaliana) accessions using PHENOPSIS, an automated phenotyping platform. Soil content adjusted at early stage plant development maintained a constant level until reproductive age achieved. The were...
The use of standardized plant material grown in a controlled environment can facilitate disentangling the many impacts climate change on grapevine production and quality. <i>Microvine</i> is natural gibberellic acid-insensitive mutant showing dwarfism early, continuous flowering along vegetative axes. was initially proposed as model for genetics. Here, we examined its suitability characterizing reproductive growth development patterns responses to elevated temperature. A series experiments...
High-throughput phenotyping of plant traits is a powerful tool to further our understanding growth and its underlying physiological, molecular, genetic determinisms. This protocol describes the methodology standard experiment in PHENOPSIS automated platform, which was engineered INRA-LEPSE (https://www6.montpellier.inra.fr/lepse) custom-made by Optimalog company. The seminal method published Granier et al. (2006). platform used explore test various ecophysiological hypotheses (Tisné al.,...
Introduction Global warming is a major threat to yield sustainability in most crops, including grapevine. Whether or not grapevine fruitfulness impaired by an imbalance between carbon supply and demand caused high temperatures was investigated the present study. Methods Five experiments were conducted on Microvine , natural mutant of that insensitive gibberellins, presents with dwarf stature, has continuous flowering along vegetative axes. The last property used infer temporal patterns...
Aim: The success of inflorescence primordia initiation and differentiation within latent buds (i.e. bud fruitfulness) is a critical issue for grapevine yield sustainability under climate change. aim the present study was to track timing rate development in along cane quantify their responses elevated day/night (D/N) temperatures.Methods Results: experiments were conducted controlled conditions, using microvine model, which suitable establishment small areas. Two imagery methods analyzing...
