Tracking Cell Signals in Fluorescent Images [PDF]

, 2005
In this paper we present the techniques for tracking cell signal in GFP (Green Fluorescent Protein) images of growing cell colonies. We use such tracking for both data extraction and dynamic modeling of intracellular processes.

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),

J Regularization Improves Imbalanced Multiclass Segmentation [PDF]

, 2019
We propose a new loss formulation to further advance the multiclass segmentation of cluttered cells under weakly supervised conditions. When adding a Youden's J statistic regularization term to the cross entropy loss we improve the separation of touching

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 ...

A Dynamic Co-expression Map of Early Inflorescence Development in Setaria viridis Provides a Resource for Gene Discovery and Comparative Genomics

Frontiers in Plant Science, 2018
The morphological and functional diversity of plant form is governed by dynamic gene regulatory networks. In cereal crops, grain and/or pollen-bearing inflorescences exhibit vast architectural diversity and developmental complexity, yet the underlying ...

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.

Tandemly duplicated TaERF109 genes confer drought tolerance and post‐drought recovery in wheat

Journal of Integrative Plant Biology, EarlyView.
Tandemly duplicated TaERF109 transcription factor genes in wheat modulate growth traits and enhance drought tolerance by regulating the TaMADS56 transcription facto gene, cytokinin biosynthesis‐related genes, and nicotianamine synthase genes, revealing the critical role of tandemly duplicated genes in the coordination of stress responses and ...

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.

A leucine‐rich‐repeat receptor‐like kinase SERL1 phosphorylates and stabilizes OsALDH2B1 to promote alkaline tolerance and grain size in rice

Journal of Integrative Plant Biology, EarlyView.
The rice aldehyde dehydrogenase OsALDH2B1 enhances grain size and tolerance to alkaline soil by repressing GRAIN SIZE 3 and activating catalases. SERL1‐mediated phosphorylation stabilizes OsALDH2B1 under stress, establishing a signaling axis that overcomes growth‐defense trade‐offs and provides a direct target for breeding high‐yield, alkaline ...
