Cytokinin-Dependent Control of GH3 Group II Family Genes in the Arabidopsis Root

Plants, 2019
The Arabidopsis root is a dynamic system where the interaction between different plant hormones controls root meristem activity and, thus, organ growth.

Ovule is a lateral organ finally differentiated from the terminating floral meristem in rice

Developmental Biology, 2011
The floral meristem is the homeostatic source of floral organs in angiosperms. In rice, after stamen and carpel differentiation, the floral meristem is terminated and exhausted to produce an ovule. To elucidate underlying mechanisms controlling the continuous process from floral meristem termination to ovule formation, we investigated two rice mutants ...

RETINOBLASTOMA-RELATED Protein Stimulates Cell Differentiation in theArabidopsisRoot Meristem by Interacting with Cytokinin Signaling [PDF]

The Plant Cell, 2013
AbstractMaintenance of mitotic cell clusters such as meristematic cells depends on their capacity to maintain the balance between cell division and cell differentiation necessary to control organ growth. In the Arabidopsis thaliana root meristem, the antagonistic interaction of two hormones, auxin and cytokinin, regulates this balance by positioning ...

GeARF5/GeIAA33‐GeSWEET14 module balances the secondary metabolic biosynthesis to increase the yield and quality in Gastrodia elata

Journal of Integrative Plant Biology, EarlyView.
Auxin signaling regulates the formation of vegetative propagation corms in Gastrodia elata by regulating sugar‐acid interconversion, which in turn regulates polysaccharide and starch biosynthesis as well as biosynthesis of the bioactive metabolite gastrodin.

The Medicago truncatula nodule identity gene MtNOOT1 is required for coordinated apical-basal development of the root

BMC Plant Biology, 2019
Background Legumes can utilize atmospheric nitrogen by hosting nitrogen-fixing bacteria in special lateral root organs, called nodules. Legume nodules have a unique ontology, despite similarities in the gene networks controlling nodule and lateral root ...

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

Journal of Integrative Plant Biology, EarlyView.
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

Journal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

The transcription factors TaABI4 and TaNAC‐A1 fine‐tune TaCYP94‐A1 transcription to modulate seed dormancy in wheat

Journal of Integrative Plant Biology, EarlyView.
A module involving the transcription factors TaABI4 and TaNAC‐A1, and the cytochrome P450 TaCYP94‐A1 precisely regulates seed dormancy levels through plant hormone crosstalk, providing targets for improving resistance to pre‐harvest sprouting in wheat.

Unique and Conserved Features of the Barley Root Meristem

Frontiers in Plant Science, 2017
Plant root growth is enabled by root meristems that harbor the stem cell niches as a source of progenitors for the different root tissues. Understanding the root development of diverse plant species is important to be able to control root growth in order
