U. S. A. Rev. Although these processes of reprogrammed development serve considerably different physiological functions to meet their distinct adaptive strategies, they are similar at the cellular level, namely, responding to the environmental signals that trigger cell cycle re-entry to generate de novo organogenesis (Figure 1). Rev. After contact with the host, the epidermis cells at the haustorium apex become densely protoplasmic with enlarged nuclei, followed by rapid elongation of the cells, which are often called intrusive cells or palisade cells (Musselman and Dickison, 1975; Neumann et al., 1998). Development 143, 1442–1451. 28, 60–67. Compared with animals, plants generally possess a high degree of developmental plasticity and display various types of tissue or organ regeneration. (2009). Combining these, we discuss the generality of developmental reprogramming processes to shed light on the uniqueness of plant development. (2009). Transcriptomic and metabolomic reprogramming from roots to haustoria in the parasitic plant, Thesium chinense. We highlight the potentially shared molecular mechanisms across the different developmental programs, especially a core network module mediated by the AUXIN RESPONSIVE FACTOR (ARF) and the LATERAL ORGAN BOUNDARIES DOMAIN (LBD) family of transcription factors.
In tissue culture we can rescue embryo in distant (intergeneric or interspecific) hybridization where poor endosperm development occur in embryos. Notably, in response to environmental cues, front-line cells, such as host plant cells adjacent to infecting bacterial cells, parasitic plant cells adjacent to host plant cells, and isolated protoplast cells, show enlargement of nuclei before starting cell division or differentiation.

Control of plant cell differentiation by histone modification and DNA methylation. Plant Cell 28, 1795–1814. Auxin transport network underlies xylem bridge formation between the hemi-parasitic plant Phtheirospermum japonicum and host Arabidopsis. J. Linn. Given that LBD and ARF gene evolution can be traced back to aquatic ancestors of land plants, followed by relatively recent lineage-specific expansions on land (Finet et al., 2012; Chanderbali et al., 2015; Kong et al., 2017; Mutte et al., 2018; Martin-Arevalillo et al., 2019), evolution of the ARF-LBD module allowed ancestral plants to innovate the developmental reprogramming in response to various types of signals to adapt to diversified land environments.
