Optimation of Callus Induction from Piper betle L. var Nigra Explants with Various Concentrations of Coconut Water and Addition of 2,4-D and NAP [PDF]

open access: yes, 2020
Black betle [Piper betle (L.) var. Nigra] is one of the endemic species from Indonesia that has potential as medical plant because this plant can produce secondary metabolites such as alkaloids, flavonoids, tannins, steroids, terpenoids and saponins ...

A single-cell transcriptome atlas reveals the transcriptionally earliest state in rice callus

open access: yesBMC Plant Biology
Background The cell fate transition of pluripotent callus from somatic cells plays an important role in plant development studies and crop genetic improvement. Embryonic callus is a group of totipotent cells derived from the founder cells responsible for

RNA interference of the ecdysone receptor gene AgEcR in a wolfberry ‐ specialized strain of Aphis gossypii Glover affects its survival and fecundity and confers resistance in transgenic goji (Lycium barbarum L.)

open access: yesPest Management Science, EarlyView.
AgEcR, an ecdysone receptor from Aphis gossypii, is an RNA interference (RNAi) target. Artificial diet screening of five double ‐ stranded RNA fragments identified dsAgEcR2 targeting the D/E junction as the most potent. Transgenic goji expressing dsAgEcR2 caused molting defects and reduced fecundity, suppressing population growth and offering a ...

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries

open access: yesPest Management Science, Volume 81, Issue 4, Page 1740-1751, April 2025.
Electrolyzed water treatments could have promising applications in the grapevine nursery process to prevent or reduce infections caused by fungal trunk pathogens on grapevine propagation material. Abstract BACKGROUND Grapevine producers demand solutions to control fungal trunk pathogens (FTPs) in nurseries.

Engineering Flexible Nanofibrous Hydroxyapatite Scaffolds With Tunable Degradation and Mechanical Properties for Bone Regeneration

open access: yesSmall, EarlyView.
Conventional hydroxyapatite ceramics are brittle and poorly resorbable, limiting their use in bone repair. To overcome these limitations, flexible scaffolds are fabricated using ceramic nanofibers as structural building blocks. Adjusting nanofiber characteristics allows modulating the mechanical properties and degradation, providing a versatile ...

Multiscale Effects of Environmentally Relevant Mixtures Containing Two Estrogenic Endocrine Disruptors, Chlordecone and Propylparaben, in Hydra vulgaris Pallas, 1766

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study investigates the chronic effects of chlordecone (CLD) and propylparaben (PP), two pro‐estrogenic endocrine disruptors, on Hydra vulgaris Pallas, 1766 using a multiscale approach over a 14‐day exposure period. Environmentally relevant concentrations of CLD (0.5, 5, 20 μg L−1) and PP (0.01, 0.05, 0.40 μg L−1) were tested individually ...

Differentiation of embryoids and plantlets from shoot callus of sandalwood

open access: yes, 1979
Callus cultures of sandalwood (Santalum album L.) were established from shoot segments and shoot tips of trees over 20 years old. Shoots were induced directly from shoot tip callus, while in shoot segments embryoids developed from the callus within 4 ...

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

open access: yesVIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.
