S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

From hepatic to hematopoietic: LRH‐1's expanding cellular repertoire to the immune system

The FEBS Journal, EarlyView.
The nuclear receptor LRH‐1 is a well‐characterized regulator of endodermal tissue. Yet, increasing evidence indicates that LRH‐1, although expressed at low levels, is also a critical regulator of the hematopoietic system. LRH‐1 regulates the immune system by contributing to immune cell‐specific functions.

Circadian disruption elicits sex‐specific gut microbiota, endocannabinoidome, and lipid mediator responses

The FEBS Journal, EarlyView.
Circadian disruption via constant light induces sex‐specific remodeling of the microbiome, lipid mediators, and immune responses. Females exhibit broader gut microbiota alterations, reduced jejunal oxylipins, increased hypothalamic N‐acylethanolamines, and a more inflammatory cytokine profile. Muscle responses are sex‐ and fiber type‐dependent: females

Defining the role of αC helix interactions in the activation of the integrin αI domain

The FEBS Journal, EarlyView.
The α2I domain of the α2β1 integrin contains a distinctive αC helix and a conserved Arg288‐Glu318 ion pair that stabilizes the closed state of the domain. Disruption of this ion pair in the activated α2I variant unwinds the αC helix, which allows interaction with additional collagen‐binding sites increasing collagen binding.

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Watermelon genotype‐independent transformation via direct organogenesis from the cotyledon base

Journal of Integrative Plant Biology, EarlyView.
Inducing adventitious buds from the base of watermelon cotyledon through direct organogenesis resulted in a watermelon genetic transformation system that overcomes regeneration barriers and genotype limitations.

Rational reduction of a sorghum SynCom that preserves growth promotion reveals flavonoid‐mediated plant–microbe interactions

New Phytologist, EarlyView.
Synthetic community complexity reduction designs. Summary Plant growth is influenced by the composition of its associated microbiome. The inherent complexity and functional redundancy of natural plant microbiomes present a formidable barrier to understanding the myriad biological interactions therein.

A Novel AP2/ERF Transcription Factor Controls Trichome Initiation and Fruit Development in Cucumber

Plant Biotechnology Journal, EarlyView.
ABSTRACT Trichomes, the hair‐like outgrowths of the plant epidermis, are critical for defence, reproduction and development. However, the underlying molecular mechanisms governing their initiation remain elusive. Here, we identified CsGL2, an AP2/ERF transcription factor, as a key integrator controlling trichome initiation and fruit development in ...

miR172‐AP2 Controls Age‐Dependent Regeneration Competence in Populus

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plants maintain remarkable regenerative potential, yet this capacity declines with developmental age, limiting clonal propagation and biotechnological applications. Here, we show that the miR172‐AP2 module serves as a central determinant of regeneration competence in Populus.
