Adaptation and Acclimation of Gametophytic Traits to Heat Stress in a Widely Distributed Wild Plant Along a Steep Climatic Gradient

Ecology and Evolution, Год журнала: 2025, Номер 15(4)

ABSTRACT Climate change‐induced heat waves often reduce seed yields and quality via high‐temperature effects in the gametophytic phase. Yet, contrast to model crop species, ability of pollen ovules adapt or acclimate stress wild plants remains poorly understood. To address this gap, we examined adaptation acclimation potential six traits 11 Silene vulgaris populations across a temperature gradient Europe. First, cultivated common garden reveal differences indicative adaptation. Next, assessed their by subjecting flowering two chronic (CHS) treatments: moderate (35°C/30°C) severe (40°C/35°C) for 18 days. Also, estimated CHS on quantity quality. The experiment showed no intraspecific variation gradient, suggesting these may not influence reproductive local habitats. During CHS, female gametophyte was less temperature‐sensitive than male. Moderate led larger ovaries with more large‐sized ovules, while reduced ovule numbers but increased size. Both treatments decreased grain numbers, size, anther length, causing greater reductions. These reductions lower yield Under both treatments, did vary along except size under which warmer climates. Our findings revealed lack mechanisms (except size) gradient. suggest that rely alternative strategies, such as shifts physiology biochemistry phenology, respond thermal associated waves.

Temperature and Watering Regime Interactions in Shaping Canola Reproductive Yield and Seed Quality

Seeds, Год журнала: 2025, Номер 4(2), С. 21 - 21

Crops are continually subjected to frequent and extreme changes in climate, such as high temperatures soil water deficits. Many studies have shown the individual effects of these factors on plants, but their combined reproductive growth subsequent seed germinability received little attention. In this study, we used canola (Brassica napus) plants grew them through lifecycle under two temperature regimes (20/10 °C 24/14 °C, 16 h light/8 dark) controlled-environment chambers. Half were watered field capacity (well-watered) other half at wilting point (water-stressed). During stage, flower, silique, traits measured. Higher decreased petal width by 1.17 times increased anthocyanins 1.03 times. The deficit silique length total number 1.21 1.32 times, respectively, nectar sugar concentration 1.28 volume was affected interaction water. lowest water-stressed higher (2.66 ± 0.29 µL per flower) highest well-watered same regime (5.73 0.37 flower). conclusion, less pronounced than yield.

Assessing Jatropha curcas pollen viability: a comparative assessment of transgenic and non-transgenic pollen under various environmental conditions using rapid staining technique

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Апрель 29, 2025

Introduction Pollen plays a critical role in transgene flow between non-transgenic plants, influencing gene dispersal and environmental risk considerations. Jatropha ( curcas ) is promising biofuel crop, offers an opportunity to study pollen biology, particularly transgenic lines. Understanding viability under different conditions essential for assessing potential risks associated with cultivation. Methods of X8#34 was assessed using various staining techniques. An optimized double-staining technique Fluorescein Diacetate (FDA) Propidium Iodide (PI) developed, effectively differentiated viable (green fluorescence) from non-viable (red fluorescence). The effects temperatures (18°C, 28°C, 30°C 35°C, 40°C 45°C) UV-B irradiation (3 15 W/m2) on ware examined. Additionally, field-relevant conditions, including sunny cloudy/shady atmospheric environments. Results A significant reduction observed extreme temperature stress. Among tested, high (35°C, led decline viability, notable differences emerging min incubation. exposure high-intensity (12 W/m2 significantly reduced the viability. Under field relevant condition, dropped 19% 16% after 45 incubation complete loss recorded 90 both genotypes. In over 97% lost 240 Statistical analysis confirmed no difference across all tested conditions. Discussion This provides first comprehensive assessment Jatropha. findings highlight influence factors, exposure, longevity. double (FDA + PI) reliable method may be useful evaluations Given rapid likelihood via appears limited.

Patterns and Drivers of Pollen Temperature Tolerance

Plant Cell & Environment, Год журнала: 2024, Номер unknown

Опубликована: Окт. 24, 2024

ABSTRACT Pollen, a pivotal stage in the plant reproductive cycle, is highly sensitive to temperature fluctuations, impacting seed quality and quantity. While importance of understanding pollen limits ( Tmin , Topt Tmax – collectively PTLs) recognized, comprehensive synthesis underlying drivers lacking. Here, we examined PTLs, correlating them with vegetative tissue thermotolerance assessing variability at intra‐ interspecific levels across 191 species contrasting phylogeny, cultivation history, growth form ecology. At level, PTLs range from 9.0 42.4°C, considerable differences among individual species. Vegetative showed greater tolerance both low high temperatures than pollen. A significant, though weak, correlation was observed between leaf tolerance. Pollen heat independent that leaves stems. The greatest intraspecific cold ), followed by . Phylogenetic analysis revealed family‐level conservation all three measures. Climate emerged as significant PTL driver tolerance, colder stable climates exhibiting enhanced Cultivated wild did not differ their tolerances. Herbaceous plants higher compared shrubs trees, potentially reflecting divergent thermal conditions during anthesis. This study provides first formal complex relationships limits, characteristics environmental factors, providing crucial insights into climate change impacts on reproduction.

Pollen, a pivotal stage in the plant reproductive cycle, is highly sensitive to temperature fluctuations, impacting seed quality and quantity. While importance of understanding pollen limtits (Tmin, Topt, Tmax – collectively PTLs) recognized, comprehensive synthesis underlying drivers lacking. Here, we examined PTLs, correlating them with vegetative tissue thermotolerance assessing variability at intra- interspecific levels across 198 species contrasting phylogeny, cultivation history, biology ecology. At level, PTLs range from 6.1 39.5 0C, considerable differences among growth forms histories. Positive correlations were found between leaf/stem tolerances. Notably, cold tolerances varied significantly populations, while Topt values remained stable. Phylogenetic analysis revealed family-level conservation tolerance, heat tolerance's independence evolutionary history. Climate emerged as significant PTL driver, higher elevations latitudes exhibiting enhanced tolerance. Cultivated displayed narrower (10.3-39.9 °C) than their wild counterparts (5.2-42.3 °C), highlighting potential crop vulnerabilities global warming. Herbaceous plants exhibited superior tolerance both low high temperatures compared shrubs trees, reflecting divergent thermal conditions during anthesis. This study illuminates complex relationships limits, characteristics, environmental factors, providing crucial insights into climate change impacts on reproduction.
