“…Together with the large overlap in gene expression at the whole genome level between the two stages of the life cycle (Borges et al, 2008), selection at the gametophytic level can be effective and has been proposed as a complementary strategy to traditional sporophyte-based breeding strategies (reviewed in Hormaza and Herrero, 1996). Furthermore, gametophytic selection might have significant evolutionary implications as long as selection at the gametophytic level could change gene frequencies between generations (Hedhly et al, 2009). …”

“…However, increasing available farmlands is hardly feasible without plowing up virgin lands and forests and, thus, deteriorating further the already threatened natural habitats and biodiversity (Trewavas, 2002). Second, the recent linear trend of 0.74ºC increase in the average global near-surface temperature registered between 1906 and 2005 (Solomon et al, 2007) seems to support the fact that, indeed, we are facing an unequivocal global warming which may represent another challenge to plant productivity and geographic distribution (Hedhly et al, 2009). …”

Research on plant responses to temperature stress is receiving increased interest due to the growing awareness about global warming. High and low temperature stresses help establish the narrow geographic distribution of some cultivated plants, the limited geographic extension of some other economically nutritionally important species, and also induce irregular bearing for some species. However, the understanding of plant responses to temperature stress lags behind other biotic and abiotic stresses probably due to the complex response at the molecular, cellular, and organismal level. Temperature stress affects, indeed, many developmental processes during the plant's life cycle. However, the reproductive stage, the outcome of which represents the economic value for many cultivated plants, is especially vulnerable. Here the effect of low and high temperature stresses during the flowering phase is reviewed in flowering plants in an attempt to unravel sensitive stages that are behind irregular cropping. The review presents detailed findings from 33 previously published reports spanning 19 different flowering plant species. Both the male and female organs of the flower are especially sensitive to temperature fluctuations both during their development before pollination and during the post-pollination stage. The effect of temperature stress is, however, obscured by the complex male-female interaction superimposed on the individual behavior of each organ. Interestingly, a review of the literature on this topic shows that genetic variation does exist in reproductive behavior under temperature fluctuations. This genetic diversity must be preserved and characterized in further detail to understand how plants naturally cope with changing environmental conditions, which will, undoubtedly, help us to design better strategies to face current and future challenging temperature fluctuations.

In order to explore how plant autotoxicity changes with climate warming, the autotoxicity of P. schrenkiana needles' water extract, organic extract fractions, and key allelochemical DHAP was systemically investigated at the temperature rising 2 and 4°C based on the data‐monitored soil temperature during the last decade in the stage of Schrenk spruce regeneration (seed germination and seedling growth). The results showed that the criterion day and night temperatures were 12°C and 4°C for seed germination, and 14°C and 6°C for seedling growth, respectively. In the presence of water extract, the temperature rise of 2°C significantly inhibited the germination vigor and rate of P. Schrenkiana seed, and a temperature rise of 4°C significantly increased the inhibition to the seedling growth (P < 0.05). Among the three organic fractions, the low‐polar fraction showed to be more phytotoxic than the other two fractions, causing significant inhibitory effects on the seed germination and growth even at low concentration of 0.1 mg/mL, and the inhibition effect was enhanced as temperature increased. The temperature rise significantly enhanced the promotion effect of DHAP, while the inhibition effect of temperature rise became less important with increasing concentration of DHAP. This investigation revealed that autotoxicity of P. schrenkiana was affected by the climate warming. As expected, it provided an insight into the mechanism and effectiveness of allelopathy in bridging the causal relationship between forest evolution and climate warming.

“…Even though the changes in climatic drivers and other related abiotic aspects are expected to be larger at the end of the century, the effects of current global warming are already visible in several ecosystems (Hedhly et al, 2008;Van Mantgem et al, 2009) and affect the ecology of many species, including their geographical distribution, phenology, biotic interactions and extinction risks (for a review see Peñuelas et al, 2013). Temperature has been shown to influence seed production (Walck et al, 2011;Carón et al, 2014a), germination, establishment (Lewis et al, 1999;Jensen, 2001) and growth of plants (Rapp et al, 2012).…”

“…Even though climate change will likely affect all plant life cycle phases, plant reproduction has been suggested to be especially sensitive (Hedhly et al, 2008;Walck et al, 2011). In many cases, warming has been shown to positively influence seed germination McCarragher et al, 2011) or to enhance seedling survival and growth (Piper et al, 2013).…”

a b s t r a c tClimate projections indicate that temperatures will increase by up to 4.5 • C in Europe by the end of this century, and that more extreme rainfall events and longer intervening dry periods will take place. Climate change will likely affect all phases of the life cycle of plants, but plant reproduction has been suggested to be especially sensitive. Here, using a combination of approaches (soil heaters and different provenances along a latitudinal gradient), we analyzed the regeneration from seeds of Acer platanoides and A. pseudoplatanus, two tree species considered, from a management point of view, of secondary relevance. We studied germination, seedling survival and growth in a full-factorial experiment including warming and changes in watering frequency. Both species responded to warming, watering frequency and seed provenance, with stronger (negative) effects of warming and provenance than of watering frequency. In general, the central provenances performed better than the northernmost and southernmost provenances. We also detected interactive effects between warming, watering frequency and/or seed provenance. Based on these results, both species are expected to show dissimilar responses to the changes in the studied climatic factors, but also the impacts of climate change on the different phases of plant regeneration may differ in direction and magnitude. In general increases in the precipitation, frequency will stimulate germination while warming will reduce survival and growth. Moreover, the frequent divergent responses of seedlings along the latitudinal gradient suggest that climate change will likely have heterogeneous impacts across Europe, with stronger impacts in the northern and southern parts of the species' distribution ranges.
