SUMMARY Plants have developed a sophisticated regulatory network that coordinates gene expression in meristematic zones in response to environmental conditions. Here, we identified a protein in Arabidopsis ( Arabidopsis thaliana ) that interacts with Armadillo BTB Arabidopsis protein 1 (ABAP1), a negative regulator of the cell cycle in plants. We characterized the ABAP1 interacting protein (named AIP10) investigating its role in modulating plant development. T‐DNA insertion lines with silenced expression of AIP10 …

Summary Plant host cell‐cycle hyperactivation is essential for nematode feeding site (NFS) ontogenesis, but the balanced mitotic and endoreplication cycles must occur for homeostasis. Alterations in core cell cycle gene expression are well known to disturb root‐knot and cyst‐NFS development. Herein, our investigation focused on the activity of E2FA and E2FB transcription factors in root‐knot nematode‐induced galls in Arabidopsis thaliana controlling both the mitotic and endocycles through the activation of S‐phase…

Summary Root‐knot nematodes (RKN; Meloidogyne species) are plant pathogens that introduce several effectors in their hosts to facilitate infection. The actual targets and functioning mechanism of these effectors largely remain unexplored. This study illuminates the role and interplay of the Meloidogyne javanica nematode effector ROS suppressor (Mj‐NEROSs) within the host plant environment. Mj‐NEROSs suppresses INF1‐induced cell death as well as flg22‐induced callose deposition and reactive oxygen species (ROS) pro…

ABSTRACT The anaphase promoting complex 7 (AtAPC7) is an APC/C subunit expressed in different organs of Arabidopsis thaliana and conserved among eukaryotes. A variant of the complete APC7 protein, containing its C‐terminal region (named APC‐CT), shows a high homology with a tobacco viral replication inhibitor (IVR‐like) protein that reduces plant susceptibility to RNA viruses. Here, the role of the AtAPC7 gene was investigated by characterizing Arabidopsis plants overexpressing the full‐length AtAPC7 ( APC7 OE ) a…
