“…Cadmium has been shown to negatively affect pollen germination accompanied with a disruption of pollen tube morphology in multiple plant species [219,220]. Even very low Cd concentrations of 0.01 µg mL −1 were able to inhibit either pollen germination or tube growth in Vicia angustifolia and Vicia tetrasperma , indicating that this process is very sensitive to Cd [221].…”

Anthropogenic pollution of agricultural soils with cadmium (Cd) should receive adequate attention as Cd accumulation in crops endangers human health. When Cd is present in the soil, plants are exposed to it throughout their entire life cycle. As it is a non-essential element, no specific Cd uptake mechanisms are present. Therefore, Cd enters the plant through transporters for essential elements and consequently disturbs plant growth and development. In this review, we will focus on the effects of Cd on the most important events of a plant’s life cycle covering seed germination, the vegetative phase and the reproduction phase. Within the vegetative phase, the disturbance of the cell cycle by Cd is highlighted with special emphasis on endoreduplication, DNA damage and its relation to cell death. Furthermore, we will discuss the cell wall as an important structure in retaining Cd and the ability of plants to actively modify the cell wall to increase Cd tolerance. As Cd is known to affect concentrations of reactive oxygen species (ROS) and phytohormones, special emphasis is put on the involvement of these compounds in plant developmental processes. Lastly, possible future research areas are put forward and a general conclusion is drawn, revealing that Cd is agonizing for all stages of plant development.

“…In addition, Cd may affect pollen development (Muradoğlu, Beyhan, & Sonmez, 2017; Pan et al, 2017; Hattab, Hedheli, Banni, Boussetta, & Herrero, 2010). In tobacco ( Nicotiana tabacum ) and lily ( Lilium longiflorum ), the presence of low Cd concentration (10 −12 M of CdCl 2 ) in the growing media exerted slight stimulatory effects on pollen tube germination, growth rate and tube elongation (Sawidis, 2008).…”

Studies involving the effects of long‐term exposure of plants to cadmium (Cd) are not usual, hence, data about Cd‐induced impacts on plant reproductive organs are scarce. The lack of robust information about this matter is surprising and also worrying because it is not yet clear whether (and how strong) Cd influences yield, and quality of fruits and seeds. Such information is necessary to guide strategies to manage crops and to avoid negative impacts on the environment and human health. This review gathers information about the effects of long exposure of flowers, fruits and seeds to Cd. A critical analysis of the data related to this matter, which have been published in the last 30 years, was performed. Ecological and evolutionary aspects were also discussed, and new insights were provided. The information about Cd‐induced effects on fruit and seed quality is relevant to support not only further scientific studies, but also environmental, economic and health policies in times of increasing heavy metal pollution in agricultural areas.
