“…Stigmas of several angiosperms accumulate ROS (mainly H 2 O 2 ) constitutively (McInnis et al, 2006;Zafra et al, 2016). Stigmatic ROS is thought to be involved in signaling networks that promote pollen germination and pollen tube growth on the stigma (Lan et al, 2017). In ornamental kale (Brassica oleracea var.…”

“…acephala), ROSscavenging flavanoids and ROS play antagonistic roles in mediating pollination. Flavonoid levels decline as the stigma reaches maturity resulting in ROS accumulation in the stigma and allowing compatible pollination to occur (Lan et al, 2017). ROS has also been implicated in Self-Incompatibility (SI), the reproductive barrier that plants utilize to prevent self-pollination The darkness of blue color indicates the likelihood of gene expression based on the number of experimental replicates with a present (P) call.…”

Reactive oxygen species (ROS) are toxic by-products of aerobic metabolism. In plants, they also function as important signaling molecules that regulate biotic and abiotic stress responses as well as plant growth and development. Recent studies have implicated ROS in various aspects of plant reproduction. In male gametophytes, ROS are associated with germline development as well as the developmentally associated programmed cell death of tapetal cells necessary for microspore development. ROS have a role in regulation of female gametophyte patterning and maintenance of embryo sac polarity. During pollination, ROS play roles in the generation of self-incompatibility response during pollen-pistil interaction, pollen tube growth, pollen tube burst for sperm release and fertilization. In this mini review, we provide an overview of ROS production and signaling in the context of plant reproductive development, from female and male gametophyte development to fertilization.

“…Recently, the ROS accumulation controlled by flavonoids and the ROS metabolic enzymes were identified in the stigma of ornamental kale (Brassica oleracea var. acephala), a selfincompatible (SI) species (Lan et al, 2017). The decreased ROS levels in the ornamental kale stigma after treatment with exogenous flavonoid (kaempferol) do not compromise the SI response of the stigma, but the attachment and germination of the compatible pollen is drastically reduced.…”

The male-female interactions in pollination mediate pollen hydration and germination, pollen tube growth and fertilization. Reactive oxygen species (ROS) derived from both male and female tissues play regulatory roles for the communication between the pollen/ pollen tube and female tissues at various stages, such as pollen hydration and germination on the stigma, pollen tube growth in the pistil and pollen tube reception in the female gametophyte. In this minireview, we primarily summarize the recent progress on the roles of ROS signaling in male-female interactions during pollination and discuss several ROSregulated downstream signaling pathways for these interactions. Furthermore, several ROS-involved downstream pathways are outlined, such as Ca 2+ signaling, cell wall cytomechanics, the redox modification of CRP, and cell PCD. At the end, we address the roles of ROS in pollen tube guidance and fertilization as future questions that merit study.

“…Reactive oxygen species (ROS) are known to play important roles in diverse physiological processes, [25][26][27][28][29][30][31][32][33] including pollen tube growth. 25,27,34 Many flowering plants constitutively accumulate more ROS in mature than bud-stage stigmas, [35][36][37][38] suggesting a potential involvement of ROS in pollen-stigma interactions. It was reported that high concentrations (between 40 mM and 100 mM) of the ROS inhibitor N-acetyl-L-cysteine (NAC) completely abolished stigmatic ROS in ornamental kale (B. oleracea var.…”
