O objetivo deste trabalho foi estabelecer um protocolo para a regeneração in vitro de pau-rosa (Aniba rosaeodora Ducke), utilizando brotações apicais e segmentos nodais inoculados em meio de cultura com distintas con...

A study on propagation of three superior cassava Manihot esculenta( Crant) varieties i.e. Darul Hidayah, Malang-6 and Adira-4 through tissue culture technique was conducted at the Tissue Culture Lab of SEAMEO BIOTROP, Bo...

A factorial experiment was carried out using Randomized Complete Block Design layout (RCBD) at the experimental research station, College of Agriculture Engineering Science – University of Baghdad- Al-Jadriyah, in an...

α-L-Arabinofuranosidase, α- and β-D-xylosidase, and β-D-glucosidase activity was detected in the soluble fraction (S-F) extracted with water and in the NaCl-released fraction (NaCl-F) extracted with a high-salt conce...

BackgroundTransmembrane Emp24 Domain Containing 2 (TMED2) is involved in various cancers, but its role in diffuse large B-cell lymphoma (DLBCL) remains unclear. This study investigated TMED2’s expression, biological fu...

ABSTRACT The objective of this study was to establish a protocol for callus induction and betacyanin production in plants of Alternanthera brasiliana. Explants of A. brasiliana and five combinations of cytokinin and auxi...

A highly efficient protocol for the regeneration of plantlets of lisianthus (cut flowers plant) was established via direct and indirect organogenesis induced from leaves explants. In direct pathway, a reliable strategy f...

Senescence and degreening are the most important features that determine loss of quality during postharvest of broccoli. During senescence, chlorophylls are degraded with the purpose of avoiding presence of photoactive m...

To mitigate the environmental impact of excessive urea use, this study investigates the foliar application of urea and ethephon as a more efficient alternative to soil application, aiming to optimize nitrogen use while s...

ABSTRACT The aim of this study was to evaluate the in vitro germination of zygotic embryos and seeds of Caesalpinia ferrea Martius and the morphogenetic responses of the explants to different concentrations of growth reg...

Abstract Female ear development during the pre- and post-silking period is critical for maize yield. Although plant growth regulators can enhance yield, their specific effects on ear morphogenesis and underlying mechanis...

ABSTRACT Stem callus cultures of carnation (Dianthus caryophyllus) local variety were grown on asynthetic medium Murashige and Skoog (MS) medium. Optimal concentration of growth regulators were observed to be 0.5mg/L 2,4...

As the summer approaches, plants experience enhanced light inputs and warm temperatures, two environmental cues with an opposite morphogenic impact. Key components of this response are PHYTOCHROME B (phyB), EARLY FLOWERI...

Abstract Epithelial-to-mesenchymal transition (EMT) is a complex and dynamic cellular process during which epithelial cells lose their polarity and cell adhesion capabilities and subsequently express mesenchymal stem cel...

Chemokine network is central to the innate and adaptive immunity and entails a variety of proteins and membrane receptors that control physiological processes such as wound healing, angiogenesis, embryo growth and develo...

We empirically examine the impact of firm-level regulatory intensity, an external force or context, on corporate strategic change (i.e. changes in a firm's financing, investing and operating decisions to boost its compet...

Abstract Background Zanthoxylum armatum is a vital economic crop in China, but its cultivation is challenged by abiotic stresses like drought and cold. Mitogen-activated protein kinase kinases (MAPKKs) are central signal...

MicroRNAs (miRNAs), a class of small non-coding RNAs, are key regulators of gene expression at post-transcriptional level and play essential roles in biological processes such as development. MiRNAs silence target mRNAs ...

Abstract Acquired immunity in plants, including systemic acquired resistance (SAR) and induced systemic resistance (ISR), plays a central role in protecting crops against a wide spectrum of pathogens and pests, ranging f...

Since the discovery of microRNAs (miRNAs) in 1993, they have been established as key post-transcriptional regulators of immune cell function. In particular, miRNAs have emerged as key modulators of CD4+ T cell activation...

Protein arginine methyltransferase 3 (PRMT3) is a type I arginine methyltransferase that catalyzes asymmetric dimethylation of arginine residues on diverse substrate proteins. Initially characterized as a regulator of ri...

IntroductionAquatic light environments are increasingly altered by human activity, yet the endocrine and molecular mechanisms enabling fish to cope with extreme photoperiods remain poorly understood. This study investiga...

Abstract Colorectal cancer (CRC) remains one of the most prevalent and lethal malignancies worldwide, with cancer stemness and metastasis being critical factors contributing to poor prognosis. While circular RNAs are eme...
