Gradient Expression of Transcription Factor Imposes a Boundary on Organ Regeneration Potential in Plants

Cell Reports, 2019
Summary: A wide variety of multicellular organisms across the kingdoms display remarkable ability to restore their tissues or organs when they suffer damage. However, the ability to repair damage is not uniformly distributed throughout body parts.

A chromosome‐scale genome assembly of Hordeum erectifolium: genomic, transcriptomic and anatomical adaptations to drought in a wild barley relative

New Phytologist, EarlyView.
Summary Wild crop relatives are valuable genetic resources for improving stress adaptation in cultivated species, but their effective use depends on high‐quality reference genomes integrated with phenotypic and molecular datasets. Hordeum erectifolium, a wild relative of barley (H.

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

New Phytologist, EarlyView.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

THE EFFECTS OF SALT STRESS ON THE SHOOT APICAL MERISTEM AND LEAF GENIERATION IN SUNFLOWER (HELIANTNUS ANNUUS L.) [PDF]

Journal of Sciences, Islamic Republic of Iran, 1996
Sunflower (Helictnthur annuus L. cvs Mehr Shafagh) seedlings were grown in nutrient solutions containing 20.5 to 70.4 mM NaCl and 0 as the control. The effects of salinity on developmental changes occurring in the shoot apices of plants were studied.

Cell walls as a stage for intercellular communication regulating shoot meristem development

Frontiers in Plant Science, 2015
Aboveground organs of plants are ultimately derived/generated from the shoot apical meristem (SAM), which is the proliferative tissue located at the apex of the stem.

Rare Natural SNP Activates SHOOT APICAL MERISTEM ENLARGER1 to Increase Branch Number and Silique Number on the Main Inflorescence in Brassica napus

Plant Biotechnology Journal, EarlyView.
ABSTRACT Brassica napus is the second most important oil crop worldwide. Number of primary branches (Branch number, BN) and silique number on the main inflorescence (SMI) are key yield‐related quantitative traits. Here, we cloned a major QTL, qDB.A09, which simultaneously influences BN and SMI.

MERISTEM-DEFECTIVE / DEFECTIVELY ORGANIZED TRIBUTARIES2 regulates the balance between stemness and differentiation in the root meristem through RNA splicing control

, 2023
Plants respond to environmental stresses through controlled stem cell maintenance and meristem activity. One level of gene regulation is RNA alternative splicing. However the mechanistic link between stress, meristem function and RNA splicing is poorly understood. The MERISTEM-DEFECTIVE (MDF)/DEFECTIVELY ORGANIZED TRIBUTARIES (DOT2) gene of Arabidopsis

Serial Spatial Transcriptomes Reveal Regulatory Transitions in Maize Leaf Development

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant leaves originate from the shoot apical meristem (SAM) and undergo a developmental process of highly coordinated gene expression regulation. To date, only a few key regulators have been identified and characterised, so the gene expression cascades responsible for leaf cell specification and differentiation from SAM remain largely elusive.

Tandem MADS‐Box Genes FUL2 and MADS1 Form a Regulatory Module to Repress Serotonin Biosynthesis via Direct ASMT5 Activation in Tomato Fruit

Plant Biotechnology Journal, EarlyView.
ABSTRACT The regulation of serotonin metabolism during fruit development and ripening remains poorly understood, despite its potential roles in plant defence and human nutrition. Here, we demonstrated that the MADS‐box transcription factor FUL2 acts as a key repressor of serotonin accumulation in tomato by forming a functional module with MADS1. CRISPR‐

Transcriptome profiling reveals key regulatory factors and metabolic pathways associated with curd formation and development in broccoli

Frontiers in Plant Science
Broccoli, a cruciferous vegetable, has a unique indeterminate inflorescence structure known as curds. It is the main edible organ of broccoli and has a rich nutritional value and health benefits.
