Abstract Gene Regulatory Networks (GRNs) play prominent roles in regulating developmental processes, and their modulation across species is a major source for evolutionary innovation. However, it remains poorly understood how GRNs are rewired between different organs within single species. This question particularly relevant pleiotropic genes, which may exhibit organ-specific GRN modulations potentially reflecting diverse functions. To address this, we investigated the NGATHA-like ( NGAL ) as model genes that regulate growth or patterning multiple Arabidopsis via two distinct pathways involving CUP-SHAPED COTYLEDON CUC KLUH KLU genes. By combining genetic analysis with gene expression characterization, uncovered significant rewiring of / regulatory module. Our findings highlight changes patterns, arising from constraints, pivotal role GRNs. Furthermore, at molecular functional levels do not always align perfectly, due to influence additional mechanisms. Altogether, our reveal associated We propose this flexibility facilitates pleiotropy.

Plant stomata play a crucial role in photosynthesis by regulating transpiration and gas exchange. Meanwhile, environmental cues can also affect the formation of stomata. Stomatal formation, therefore, is optimized for survival growth plant despite variable conditions. To adapt to conditions, plants open close stomatal pores even regulate number that develop on epidermis. There are great differences leaf structure developmental origin cell between Arabidopsis grass plants. These fine regulation due different species. In this paper, comprehensive overview molecular networks genetic mechanisms polar division fate progenitor cells dicotyledonous such as Poaceae Oryza sativa Zea mays provided. The processes mediated hormones factors summarized, model based multiple signaling pathways outlined. results contribute better understanding epidermal morphogenesis provide valuable theoretical basis gene resources improving crop resilience yield traits.
