Histone lysines can be mono-, di-, or trimethylated, providing an ample magnitude of epigenetic information for transcription regulation. In fungi, SET2 is the sole methyltransferase responsible and trimethylation H3K36. Here we show that in Arabidopsis thaliana, degree H3K36 methylation regulated by distinct methyltransferases. The homologs SDG8 SDG26 each methylate oligonucleosomes vitro, both proteins are localized nucleus. While previously reported loss-of-function sdg8 mutants have...
The homeodomain transcription factor WUSCHEL (WUS) defines the shoot stem cell niche, but mechanisms underlying establishment of WUS expression remain unclear. Here, we show that cytokinin signaling precedes in leaf axils and activates de novo axil to promote axillary meristem initiation. Furthermore, type-B Arabidopsis response regulator proteins, which are transcriptional activators pathway, directly bind promoter activate its expression. Finally, activation correlates with increased...
Zygomorphic flowers, with bilateral (dorsoventral) symmetry, are considered to have evolved several times independently in flowering plants. In Antirrhinum majus , floral dorsoventral symmetry depends on the activity of two TCP-box genes, CYCLOIDEA ( CYC ) and DICHOTOMA DICH ). To examine whether same molecular mechanism asymmetry operates distantly related Rosid clade eudicots, which asymmetric flowers thought independently, we investigated function a homologue LjCYC2 papilionoid legume,...
Abstract To maintain proper meristem function, cell division and differentiation must be coordinately regulated in distinct subdomains of the meristem. Although a number regulators necessary for correct organization shoot apical (SAM) have been identified, it is still largely unknown how their function integrated with cycle machinery to translate domain identity into cellular behavior. We show here that cyclin-dependent kinases CDKB2;1 CDKB2;2 are required both normal progression...
Stem cells in plants constantly supply daughter to form new organs and are expected safeguard the integrity of from biological invasion. Here, we show how stem Arabidopsis shoot apical meristem their nascent suppress infection by cucumber mosaic virus (CMV). The cell regulator WUSCHEL responds CMV represses accumulation central peripheral zones. inhibits viral protein synthesis repressing expression plant S-adenosyl-l-methionine-dependent methyltransferases, which involved ribosomal RNA...
Root development is tightly controlled by light, and the response thought to depend on signal transmission from shoot. Here, we show that root apical meristem perceives light independently aboveground organs activate light-regulated transcription factor
Floral patterning in Papilionoideae plants, such as pea (Pisum sativum) and Medicago truncatula, is unique terms of floral organ number, arrangement, initiation timing compared to other well-studied eudicots. To investigate the molecular mechanisms involved legumes, we have analyzed two mutants, proliferating meristem organ-2 (pfo-2), obtained by ethyl methanesulfonate mutagenesis Lotus japonicus. These mutants showed similar phenotypes, with indeterminate structures altered identities. We...
Auxin signaling is essential for organ initiation in plants. How genetic robustness controls auxin output during largely unknown. Here, we identified
Plant stem cells are hypersensitive to environmental hazards throughout their life cycle, but the mechanism by which plants safeguard cell homeostasis in response is largely unknown. The homeodomain transcription factor WUSCHEL (WUS) protein maintains pool shoot apical meristem of Arabidopsis. Here, we demonstrate that translation WUS mRNA directed an internal ribosomal entry site (IRES) located 5'-untranslated region. AtLa1 protein, RNA-binding factor, binds region and initiates...
Abstract The repeated treatment of cancer cells with chemo- or radiotherapy induces therapy resistance, but it was previously unknown whether the same effect occurs upon continuous exposure to diet-derived chemopreventive agents. We elucidated this interesting question in pancreatic ductal adenocarcinoma, which is a highly aggressive entity marked resistance toward gemcitabine and other cytotoxic drugs. isothiocyanate sulforaphane, present cruciferous vegetables, polyphenol quercetin, many...
The ERECTA family genes, (ER), ERECTA-LIKE1 (ERL1), and ERECTA-LIKE2 (ERL2), encode leucine-rich repeat receptor-like kinases in Arabidopsis thaliana. Knocking out these three genes can cause severe phenotypes, which indicates that they play significant roles plant growth development. However, the molecular mechanism within remains unclear. Here we show short hypocotyl phenotypes of er erl1 erl2 mutants are mainly due to defects cell elongation rather than division. On contrary,...
