“…At this stage (between 28 °C and 37 °C for Arabidopsis ), plants can still grow, but obvious deleterious effects begin to emerge, particularly in reproductive development. These include the inhibition of male and female gametophyte development, the inhibition of anther opening, the inhibition of pollen germination and pollen tube growth, disturbances in pollen tube guidance and fertilization, and the abortion of early embryos (Hedhly ; Sage et al ). As a result, plant fertility is reduced or completely abolished, potentially leading to significant agricultural losses.…”

The increased prevalence of high temperatures (HTs) around the world is a major global concern, as they dramatically affect agronomic productivity. Upon HT exposure, plants sense the temperature change and initiate cellular and metabolic responses that enable them to adapt to their new environmental conditions. Decoding the mechanisms by which plants cope with HT will facilitate the development of molecular markers to enable the production of plants with improved thermotolerance. In recent decades, genetic, physiological, molecular, and biochemical studies have revealed a number of vital cellular components and processes involved in thermoresponsive growth and the acquisition of thermotolerance in plants. This review summarizes the major mechanisms involved in plant HT responses, with a special focus on recent discoveries related to plant thermosensing, heat stress signaling, and HT-regulated gene expression networks that promote plant adaptation to elevated environmental temperatures.

“…They affect also pollen development and viability, which could perturb fertilization and seed development (Barnabás et al., ; Hedhly, ; Snider & Oosterhuis, ). Such modifications in pollen production mainly involve the following: (1) a reduction in the numbers of mature pollen grains; (2) abnormal pollen development, leading to decreased viability and germination capacity; and (3) abnormal anther morphology, leading to reduced pollen transfer (Bishop, Potts, & Jones, ; Devasirvatham et al., ; Hedhly, ; Sage et al., ). Both stresses applied during reproductive development lead to a reduction in fruit and seed sets (Hedhly, ; Pandey et al., ).…”

Climate change alters the abiotic constraints faced by plants, including increasing temperature and water stress. These changes may affect flower development and production of flower rewards, thus altering plant–pollinator interactions. Here, we investigated the consequences of increased temperature and water stress on plant growth, floral biology, flower‐reward production, and insect visitation of a widespread bee‐visited species, Borago officinalis. Plants were grown for 5 weeks under three temperature regimes (21, 24, and 27°C) and two watering regimes (well‐watered and water‐stressed). Plant growth was more affected by temperature rise than water stress, and the reproductive growth was affected by both stresses. Vegetative traits were stimulated at 24°C, but impaired at 27°C. Flower development was mainly affected by water stress, which decreased flower number (15 ± 2 flowers/plant in well‐watered plants vs. 8 ± 1 flowers/plant under water stress). Flowers had a reduced corolla surface under temperature rise and water stress (3.8 ± 0.5 cm2 in well‐watered plants at 21°C vs. 2.2 ± 0.1 cm2 in water‐stressed plants at 27°C). Both constraints reduced flower‐reward production. Nectar sugar content decreased from 3.9 ± 0.3 mg/flower in the well‐watered plants at 21°C to 1.3 ± 0.4 mg/flower in the water‐stressed plants at 27°C. Total pollen quantity was not affected, but pollen viability decreased from 79 ± 4% in the well‐watered plants at 21°C to 25 ± 9% in the water‐stressed plants at 27°C. Flowers in the well‐watered plants at 21°C received at least twice as many bumblebee visits compared with the other treatments. In conclusion, floral modifications induced by abiotic stresses related to climate change affect insect behavior and alter plant–pollinator interactions.

“…Possibly, early flower initiation was more sensitive to heat stress compared to more advanced flower and pollen development in field pea. The uninucleate stage of pollen development has been reported to be highly sensitive to elevated temperatures in many crop species (Sage et al., and references therein). Pre‐fertilization stages are more sensitive to heat stress compared to post‐fertilization stages (Gross & Kigel, ).…”

“…As flowering nodes are developing, flower buds will contain developing and maturing pollen in anthers and ovules within the ovary. The uninucleate stage during pollen development is highly sensitive to elevated temperatures in many crops such as chilli pepper ( Capsicum annuum and Capsicum baccatum ), coyote melon ( Cucurbita palmate ), tepary bean ( Phaseolus acutifolius ), runner bean ( Phaseolus coccineus ), maize ( Zea mays ) and many other staple crops (Sage et al., and therein; Dolferus, Ji, & Richards, ). In addition to which developmental stages are exposed to heat stress, the duration of heat exposure and the amplitude of temperature are factors determining stress intensity and the reproductive output under heat stress (Prasad et al., ).…”

Flowering plants are highly sensitive to heat stress during reproductive phase, which covers development from floral initiation to seed maturity. The objectives of this study were to diagnose high temperature effects on pollen production and morphology, production of reactive oxygen species (ROS) in pollen grains and ovules in pea cultivar “CDC Golden.” This study also investigated timing and duration of heat exposure at specific developmental stages of floral buds, open flowers and early set pods on flower and pod abortion, seed development and seed yield in “CDC Golden” and a second cultivar “CDC Sage.” The experiments were conducted in growth chambers with two temperature regimes (24/18°C and 35/18°C day/night temperature for 4–14 days) during reproductive development. Heat stress reduced the number of pollen grains per anther, induced smaller pollen grains and increased ROS production in pollen grains, but it did not affect ROS accumulation in ovules and ovule number per ovary. Heat exposure when young floral buds were visible at the first reproductive node was more detrimental to flower retention, seed set, pod development and seed yield compared to heat exposure started later when flowers at the second reproductive node were fully open.
