De novo stolon organogenesis in potato leaf callus elicited by Agrobacterium tumefaciens stimulus

Journal of Integrative Plant Biology, EarlyView.
Agrobacterium tumefaciens triggers stolon regeneration from potato leaf callus independent of T‐DNA insertion, suggesting a strategy to reprogram callus identity and expand the potential of tissue regeneration. ABSTRACT Plant cells can undergo cellular reprogramming, enabling pluripotent callus formation from excised leaves.

SlGRF1 mediates gibberellin signaling to control cut‐budding in tomato

Journal of Integrative Plant Biology, EarlyView.
Upon wounding, cytokinin increases to initiate callus formation. Gibberellin enhances this, but later blocks bud formation by suppressing SlGRF1. Wounding‐induced protein SlGRF1 triggers buds via NAM1, EPF4, and ER2. Hormonal shifts control cut‐budding phases.

CryoFluorSEM – A new approach for fluorescence and EM imaging of cryofractured plant samples

Journal of Microscopy, EarlyView.
Abstract Cryo‐scanning electron microscopy (CryoSEM) permits the preparation and detailed imaging of bulky samples while keeping them in a hydrated state. For plant biology, cryofractures give information on cell ultrastructure and tissue organisation within a much larger context that is the whole organ or organism.

VERNALIZATION2 alters early tiller development in a facultative spring hexaploid bread wheat

New Phytologist, EarlyView.
Summary An extended period of cold exposure enables the process of vernalization in winter cereals and is important for the synchronised timing of the floral transition. The cereal‐specific floral repressor VERNALIZATION2 (VRN2) has an integral role in vernalization, yet this locus remains poorly characterised in facultative spring hexaploid wheat ...

The cytotoxic influence of aluminium on Cucumis sativus L seedling roots

Acta Agrobotanica, 2013
The roots of 5-days old cucumber seedling cv. Wisconsin were incubated in the Al solutions (AICl3) of pH 4,2. AI was applied in the following concentrations: 20, 30 and 40 mg/dm3.

The annotated blueprint: integrated functional genomic resources for a model tetraploid wheat Triticum turgidum cv Kronos

New Phytologist, EarlyView.
Summary Triticum turgidum cv Kronos is a tetraploid wheat cultivar that underpins one of the most widely used community platforms for functional genomics. Over the past decade, researchers have generated c. 3000 exome‐capture (EC) and promoter‐capture (PC) datasets linked to mutagenized seed stocks, along with extensive transcriptomic and phenotypic ...

Cell cycle follows ‘pause and play’ mechanism in salt and cold stress recovery in diverse plant species

New Phytologist, EarlyView.
Summary Changes to organismal growth induced by environmental stress are orchestrated at the cellular level. These periods of stress may be followed by recovery periods, when plants have the opportunity to return to normal growth conditions. However, the cell cycle mechanisms underlying recovery are poorly understood.

Ds tagging of BRANCHED FLORETLESS 1 (BFL1) that mediates the transition from spikelet to floret meristem in rice (Oryza sativa L)

BMC Plant Biology, 2003
Background The genetics of spikelet formation, a feature unique to grasses such as rice and maize, is yet to be fully understood, although a number of meristem and organ identity mutants have been isolated and investigated in Arabidopsis and maize. Using

AGP and EXO‐LIKE genes promote brassinosteroid‐dependent anisotropic growth

New Phytologist, EarlyView.
Summary The brassinosteroid pathway promotes anisotropic cell expansion; however, the effectors in this process remain unclear. Candidates include ARABINOGALACTAN PROTEIN (AGP) genes, which are prominent brassinosteroid‐responsive transcriptional targets, and EXORDIUM (EXO)‐LIKE (EXL) genes.

Imaging and genetic toolbox to study Arabidopsis embryogenesis

New Phytologist, EarlyView.
Summary Embryogenesis in the model plant Arabidopsis thaliana provides a framework for understanding how cell polarity and patterning coordinate with hormonal signalling to establish the plant body plan. Following fertilisation, the zygote divides asymmetrically to generate apical and basal lineages, establishing the apical–basal axis that defines ...
