The front cover image is based on the Research Article Control of root‐to‐shoot long‐distance flow by a key ROS‐regulating factor in Arabidopsis by Tingting Cai et al., https://doi.org/10.1111/pce.14375.

VIVIPAROUS1/ABSCISIC ACID INSENSITIVE3-LIKE1 (VAL1) encodes a DNA-binding B3 domain protein and plays essential roles in seed maturation and flowering transition by repressing genes through epigenetic silencing in Arabidopsis. SWI-INDEPENDENT3 (SIN3)-LIKEs (SNLs), which encode scaffold proteins for the assembly of histone deacetylase complexes and...
Article
Inter‐tissue communication is instrumental to coordinating the whole‐body level behavior for complex multicellular organisms. However, little is known about the regulation of inter‐tissue information exchange. Here, we carried out genetic screens for root‐to‐shoot mobile silencing in Arabidopsis plants with a compromised small RNA‐mediated gene sil...
Article
Vascular connection is key to successful graft. Little study has been devoted to the behavior of tracheary elements (TEs), the basic component of vascular bundles, during vascular connection between scion and rootstock. Here we report the structural changes of TEs at the graft interface between two quinoa cultivars, Qaidam White-1 (QW1) and Qaidam...

Objectives: The beneficial role of ROS was probably in promoting intercellular communication by modifying membrane constituents [Liang D. A salutary role of reactive oxygen species in intercellular tunnel-mediated communication. Front Cell Dev Biol. 2018;6:2]. We investigated how the membrane lipids were responding to ROS and ROS inhibitors. Method...

Root-derived mobile signals play critical roles in coordinating a shoot’s response to underground conditions. However, the identification of root-to-shoot long-distance mobile signals has been scant. In this study, we aimed to characterize root-to-shoot endogenous mobile miRNAs by using an Arabidopsis/Nicotiana interfamilial heterograft in which th...

Scion-rootstock union formation is a critical step toward the functional assemblage of heterogeneous plants. Interfamilial scion-rootstock interaction often results in graft incompatibility during the assemblage process, and the underlying mechanisms are largely unknown. In this study, we reported that tracheary element (TE) remodeling, including T...

Background Scion–rootstock union formation is a critical step towards functional assemblage of heterogeneous plants. However, scion-rootstock interaction often results in graft incompatibility during the process of assemblage. So far, the lack of model heterografts involving both clear genetic backgrounds and taxonomically distant species greatly i...
Article
Full-text available
The reactive oxygen species, generally labeled toxic due to high reactivity without target specificity, are gradually uncovered as signaling molecules involved in a myriad of biological processes. But one important feature of ROS roles in macromolecule movement has not caught attention until recent studies with technique advance and design elegance...

In plants and nematodes, RNAi can spread from cells from which it is initiated to other cells in the organism. The underlying mechanism controlling the mobility of RNAi signals is not known, especially in the case of plants. A genetic screen designed to recover plants impaired in the movement but not the production or effectiveness of the RNAi sign...
Article
Upward long-distance mobile silencing has been shown to be phloem mediated in several different solanaceous species. We show that the Arabidopsis (Arabidopsis thaliana) seedling grafting system and a counterpart inducible system generate upwardly spreading long-distance silencing that travels not in the phloem but by template-dependent reiterated s...

Full-text available
RNA-mediated silencing in plants can spread from cell to cell and over a long distance, and such mobile silencing has been extensively studied in the past decade. However, major questions remain as to what is the exact nature of the mobile silencing signals, how the components of the RNA-directed DNA methylation pathway are involved, and why system...
Article
Self-incompatibility in Brassicaceae is determined by the interaction between S-Locus Protein 11 (SP11) on the pollen and S-receptor kinase (SRK) in the stigma. Pollen from heterozygotes generally displays products of both SP11 alleles, but in some heterozygotes SP11 expression is monoallelic, with one allele (SP11(R)) being silenced by promoter me...
Article
BREVIS RADIX is a novel plant-specific gene family with highly conserved protein sequences; the key member of this family, BRX, controls cell proliferation and root elongation in Arabidopsis. In this study, six members of rice BRX-like gene family containing the conserved BRX domain were identified in japonica rice. Phytogenetic analysis suggested...

The shoot apical meristem (SAM) is responsible for the development of all the above-ground parts of a plant. Our understanding of the SAM at the molecular level is incomplete. This study investigates the gene expression repertoire of SAMs in the garden pea (Pisum sativum). To this end, 10 346 EST sequences representing 7610 unique genes were genera...
Article
A binary GAL4-VP16-UAS transactivation system has been established in rice (Oryza sativa L.) in this study for the discovery of gene functions. This binary system consists of two types of transgenic lines, pattern lines and target lines. The pattern lines were produced by transformation of Zhonghua 11, a japonica cultivar, with a construct consisti...
