Epidermal Patterning Factor Like 9 (EPFL9), also known as STOMAGEN, is a cysteine-rich peptide that induces stomata formation in vascular plants, acting antagonistically to other epidermal patterning factors (EPF1, EPF2). In grapevine there are two EPFL9 genes, EPFL9-1 and EPFL9-2 sharing 82% identity at protein level the mature functional C-terminal domain. this study, CRISPR/Cas9 system was applied functionally characterize VvEPFL9-1 ‘Sugraone’, highly transformable genotype. A set of...
Stomata are the primary gatekeepers for CO2 uptake photosynthesis and water loss via transpiration therefore play a central role in crop performance. Although stomatal conductance (gs ) assimilation rate (A) often highly correlated, studies have demonstrated an uncoupling between A gs that can result sub-optimal physiological processes dynamic light environments. Wheat (Triticum aestivum L.) is exposed to changes irradiance due leaf self-shading, moving clouds shifting sun angle which both...
The effects of a short (30 min) heat shock (HS) on plants subsequently grown under salinity stress (SS, 200 mM NaCl) for 10 d were investigated in barley (Hordeum vulgare L.) cv. Tokak 157/37. maximum temperature HS allowing plant survival was 45 °C. root length significantly decreased by SS, whereas alone did not affect growth. Interestingly, stimulated elongation SS. An osmotic adjustment promoted leaves On the contrary, increased potential absence and partly counteracted effect SS HS+SS...
Abstract Stomata control CO2 uptake for photosynthesis and water loss through transpiration, thus playing a key role in leaf thermoregulation, water-use efficiency (iWUE), plant productivity. In this work, we investigated the relationship between several traits hypothesized that stomatal behavior to fast (i.e. minutes) environmental changes co-determines, along with steady-state traits, physiological response of grapevine surrounding fluctuating environment over growing season. No iWUE, heat...
Recent research has shown that optimizing photosynthetic and stomatal traits holds promise for improved crop performance. However, standard phenotyping tools such as gas exchange systems have limited throughput. In this work, a novel approach based on bespoke chamber allowing combined measurement of the quantum yield PSII (Fq'/Fm'), with an estimation conductance via thermal imaging was used to phenotype range bread wheat (Triticum aestivum L.) genotypes. Using dual-imaging methods...
Oilseed rape (Brassica napus L.) yield is strongly decreased by water deficit, and crop-management solutions are urgently required considering the emerging difficulties in breeding for drought-tolerant varieties. Film-forming antitranspirants (polymers) agrochemicals that, applied to crop canopy, mechanically block stomata decrease canopy transpiration. In this study, drought-protection efficacy of an adaxial-surface application at flowering stage two film-forming treatments...
Rising temperature is among the most remarkably stressful phenomena induced by global climate changes with negative impacts on crop productivity and quality. It has been previously shown that volatiles belonging to isoprenoid family can confer protection against abiotic stresses. In this work, two Vitis vinifera cv. ‘Chardonnay’ clones (SMA130 INRA809) differing due a mutation (S272P) of DXS gene encoding for 1-deoxy-D-xylulose-5-phosphate (the first dedicated enzyme...
The wine sector, among the most profitable agricultural segments, has been markedly affected by ongoing climate change impacts, such as warmer conditions with higher frequency of extreme temperatures and a trend decreasing precipitation. All this results in evaporative demand therefore occurrence water stress events leading to advancement temperature-sensitive phenological stages (e.g., budburst ripening). Such negative effects eventually affect berry development quality, especially...
Abstract The productivity of many important crops is significantly threatened by water shortage, and the elevated atmospheric CO 2 can interact with physiological processes crop responses to drought. We examined effects three different concentrations (historical ~300 ppm, ambient ~400 ppm ~700 ppm) on traits oilseed rape ( Brassica napus L.) seedlings subjected well‐watered reduced availability. Our data show (1) that, as expected, increasing level positively modulates leaf photosynthetic...
The wheat flag leaf is the main contributor of photosynthetic assimilates to developing grains. Understanding how canopy architecture strategies affect source strength and yield will aid improved crop design. We used an eight-founder population investigate genetic area, length, width angle in European wheat. For strongest locus identified, we subsequently created a near-isogenic line (NIL) pair for more detailed investigation across seven test environments. Genetic control traits...
Early budburst is becoming an increasingly challenging topic in viticulture. Anticipating vegetative resume results overall phenological advance, potential higher risks of late frost and subsequent negative effects on berry quality vine productivity. Phenotypic variation for date onset (BBCH07) known Vitis vinifera exploitation data regarding thermal requests to reach BBCH07 are critical defining new avenues Nevertheless, reproducible methods lacking progression grapevine further efforts...
Abstract Increase in drought conditions during the oilseed rape ( OSR ) reproductive phase is predicted to occur more often temperate zone, leading significant yield losses. Crop management solutions such as film antitranspirant AT applied at key drought‐sensitive growth stages on both wheat and have recently been shown alleviate drought‐induced However, there a lack of information regarding potential effectiveness reduce damage plants different soil moisture regimes. Therefore, two similar...
Crop-management solutions that simulate plant water-saving strategies might help to mitigate drought damage in crops. Winter canola (Brassica napus L.) is significantly drought-sensitive from flowering mid-pod development, and periods lead significant yield losses. In this study, the drought-protection efficacy of different chemicals with antitranspirant activity applied just before key phenological stages was tested on field-grown two years. Drought artificially imposed rain shelters. The...
Transpiration per unit of leaf area is the end-product root-to-leaf water transport within plant, and it regulated by a series morpho-physiological resistances hierarchical signals. The rate transpired sustains processes such as nutrient absorption evaporative cooling, with stomata being end-valves that maintain optimal loss under specific degrees demand soil moisture conditions. Previous work provided evidence partial modulation flux following nitrogen availability linking high nitrate...
There is a constant push on agriculture to produce more food and other inputs for different industries. Precision essential meet these demands. The intake of this modern technology rapidly increasing among large medium-sized farms. However, small farms still struggle with their adaptation due the expensive initial costs. A contribution in handling challenge, paper presents data gathering testing an in-house made, cost-effective, multispectral camera detect Flavescence dorée (FD). FD...
Isoprenoids are among the most abundant biogenic volatile compounds (VOCs) emitted by plants, and mediate both biotic abiotic stress responses. Here, we provide for first time a comparative analysis of transgenic Arabidopsis lines constitutively emitting isoprene ocimene. Transgenic Columbia-0 (Col-0) were characterized under optimal, water stress, heat conditions. Under optimal conditions, projected leaf area (PLA), relative growth rate, final dry weight generally higher in transgenics than...
The stress from excessive transpiration of water plant leaves can damage crop growth during droughts. Specific commercial biostimulant products (antitranspirants) are available to reduce when applied plants, but these expensive. Antitranspirants waste would be cheaper, and the aim this research was extract leaf wax a fresh produce processing conduct preliminary evaluation its antitranspirant efficacy. Supercritical CO2 used cauliflower leaves, after formulating for spraying, young rapeseed...
Agriculture is under constant pressure to increase the production rate and provide more food or resources for other industries. Without precision agriculture it not possible fulfil these requirements. Medium large-size farms already adopted this technology, but small are far from due high initial costs. In paper we present a bespoke affordable multispectral camera farming illustrate its application in detection of Flavescence dorée. This grapevine disease that makes great concern producers...
