“…Besides its critical roles in fertilization (Escobar-Restrepo et al, 2007 ; Duan et al, 2014 ; Ngo et al, 2014 ; Liu et al, 2016 ), it has also been implicated in the regulation of cell elongation (Guo et al, 2009 ), root hair growth (Duan et al, 2010 ), seed size (Yu et al, 2014 ), plant defense (Keinath et al, 2010 ; Kessler et al, 2010 ), and mechanosensing and calcium signaling (Shih et al, 2014 ). In the context of metabolism, FER was found to be a multifunctional regulator of starch accumulation (Yang et al, 2015 ) and sugar metabolism (Yeats et al, 2016 ; Pu et al, 2017 ). Recently, FER has been implicated in the cross-talk signaling of various phytohormones, including in ABA (Yu et al, 2012 ; Chen et al, 2016 ), auxin (Duan et al, 2010 ), BR, and ethylene (Guo et al, 2009 ; Deslauriers and Larsen, 2010 ) signaling.…”

“…In Arabidopsis, FER directly interacts with Rho of plants guanine nucleotide exchange factors (RopGEFs), activating the ROP GTPase and mediating the production of reactive oxygen species (ROS) at the entrance of the female gametophyte, thereby inducing pollen tube rupture and sperm release (Kessler et al, 2010 ; Duan et al, 2014 ; Ngo et al, 2014 ). FER is believed to function in a variety of other important processes, such as root hair elongation (Duan et al, 2010 ; Huang et al, 2013 ), starch accumulation (Yang et al, 2015 ), sugar utilization (Pu et al, 2017 ), seed development (Yu et al, 2014 ), pathogen resistance (Keinath et al, 2010 ; Kessler et al, 2010 ), and vegetative growth (Guo et al, 2009 ; Deslauriers and Larsen, 2010 ). Notably, FER has been demonstrated to play a pivotal role in the cross-talk signaling among the phytohormones that play crucial roles in Arabidopsis , including abscisic acid (ABA; Yu et al, 2012 ; Chen et al, 2016 ), auxin (Duan et al, 2010 ), brassinosteroids (BR), and ethylene (Guo et al, 2009 ; Deslauriers and Larsen, 2010 ).…”

Ethylene has long been known to be a critical signal controlling the ripening of climacteric fruits; however, the signaling mechanism underlying ethylene production during fruit development is unknown. Here, we report that two FERONIA-like receptor kinases (FERLs) regulate fruit ripening by modulating ethylene production in the climacteric fruit, apple (Malus×domestica). Bioinformatic analysis indicated that the apple genome contains 14 members of the FER family (MdFERL1–17), of these 17 FERLs, MdFERL6 was expressed at the highest level in fruit. Heterologous expression of MdFERL6 or MdFERL1, the apple homolog of Arabidopsis FER, in another climacteric fruit, tomato (Solanum lycopersicum) fruit delayed ripening and suppressed ethylene production. Overexpression and antisense expression of MdFERL6 in apple fruit calli inhibited and promoted ethylene production, respectively. Additionally, virus-induced gene silencing (VIGS) of SlFERL1, the tomato homolog of FER, promoted tomato fruit ripening and ethylene production. Both MdFERL6 and MdFERL1 physically interacted with MdSAMS (S-adenosylmethionine synthase), a key enzyme in the ethylene biosynthesis pathway. MdFERL6 was expressed at high levels during early fruit development, but dramatically declined when fruit ripening commenced, implying that MdFERL6 might limit ethylene production prior to fruit development and the ethylene production burst during fruit ripening. These results indicate that FERLs regulate apple and tomato fruit ripening, shedding light on the molecular mechanisms underlying ripening in climacteric fruit.

“…Pollen-expressed RUPO (Ruptured Pollen tube), the rice ortholog of BUPSs, is also required for pollen tube integrity; rupo pollen tubes also burst precociously in the pistil and in vitro (Liu et al, 2016). The rice Dwarf and Runtish Spikelet 1 (DRUS1) and DRUS2 are orthologous with FER, although they appear to have a broader functional range, including roles in the control of pollen viability (Nguyen et al, 2015;Li et al, 2016b;Pu et al, 2017).…”

How the pollen tube switches from a rapid polarized growth towards its target to an abrupt disintegration for sperm cell release inside the female gametophyte is puzzling. Recent studies have shown that members of the Catharanthus roseus RLK1‐like (CrRLK1L) receptor kinase family and their ligands, 5‐kDa cysteine‐rich peptide rapid alkalinization factors (RALFs), engage in an intricate balancing act involving autocrine and paracrine signaling to maintain pollen tube growth and induce timely tube rupture at the spatially confined pollen tube–female gametophyte interface. Here, we review recent progress related to pollen tube integrity control, mainly focusing on the molecular understanding of signaling as well as intracellular signaling nodes in Arabidopsis. Some missing links and future perspectives are also discussed.

“…In this pathway, LOC_Os02 g10760 (OsWR1) positively regulates waxy synthesis-related genes in rice, affects the characteristics of cuticle tissue, and thus positively regulates the drought response by affecting water loss [44]. LOC_Os01 g56330 (DRUS2) mediates a fundamental signaling process that maintains cellular activity by inhibiting protease-mediated cell degradation or possibly by affecting sugar use or exchange [45]. They were all downregulated in CH891 under Cd stress compared with 02428, suggesting that they responded differently to cadmium in different varieties of rice.…”

Background: In general, the Cd content in indica rice is higher than that in japonica. However, the mechanism underlying this discrepancy has not been elucidated. Thus, understanding the genetic and molecular basis of Cd stress between indica and japonica is highly important for rice improvement programs.Results: In this study, two varieties of rice, japonica 02428 and indica CH891, were continuously exposed to Cd, and seedlings of the two varieties at two critical stages (the 3rd and 5th day) were selected for dynamic gene analysis by the transcriptome method. The results showed that CH891 was more sensitive to Cd than 02428, and a total of 7,204 and 6,670 differentially expressed genes (DEGs) associated with Cd stress were detected on the 3rd day and 5th day, respectively. Furthermore, we divided these DEGs into three categories: SCR (sensitive variety with Cd-responsive), RCR (resistant variety with Cd-responsive) and CCR (common Cd-responsive). The enriched metabolic pathway analysis of DEGs preferentially expressed in a stage-specific and cultivar-specific manner showed that secondary metabolic processes were enriched in SCR, while protein metabolism and plant hormones were enriched in RCR. The diverted metabolic pathways might be the major reason for the different response mechanisms of Cd in indica and japonica rice.Conclusion: These results provide novel insights regarding the Cd response mechanism in rice seedlings between different varieties, and these important Cd-responsive DEGs were frequently involved in specific biological processes and metabolic pathways that might help to elucidate the mechanisms of the indica and japonica rice Cd response differences.
