Genetic control of rhizosheath formation in pearl millet [PDF]

Scientific Reports, 2022
The rhizosheath, the layer of soil that adheres strongly to roots, influences water and nutrients acquisition. Pearl millet is a cereal crop that plays a major role for food security in arid regions of sub-Saharan Africa and India.

Lipidomic insights into the immune response and pearl formation in transplanted pearl oyster Pinctada fucata martensii

Frontiers in Immunology, 2022
During pearl culture, the excess immune responses may induce nucleus rejection and death of pearl oysters after transplantation. To better understand the immune response and pearl formation, lipidomic analysis was applied to investigate changes in the ...

Research progress on formation mechanism of pearl

Heliyon
Pearls are deeply cherished for their rich color and gorgeous luster, and their quality directly affects their value. Currently, the evaluation of pearl quality is mainly based on four aspects: color, shape, size and smoothness.

Pearl Formation: Persistence of the Graft During the Entire Process of Biomineralization [PDF]

Marine Biotechnology, 2006
Most bivalves species of the genus Pinctada are well known throughout the world for production of white or black pearls of high commercial value. For cultured pearl production, a mantle allograft from a donor is implanted into the gonad of a recipient oyster, together with a small inorganic bead.

Deep sequencing of ESTs from nacreous and prismatic layer producing tissues and a screen for novel shell formation-related genes in the pearl oyster. [PDF]

PLoS ONE, 2011
BACKGROUND: Despite its economic importance, we have a limited understanding of the molecular mechanisms underlying shell formation in pearl oysters, wherein the calcium carbonate crystals, nacre and prism, are formed in a highly controlled manner.

Pearl-Chain Formation of Discontinuous Carbon Fiber under an Electrical Field

Journal of Manufacturing and Materials Processing, 2017
The purpose of this paper is to develop a theoretical derivation on aligning discontinuous carbon fiber with an applied electric field, and prove the theory with experiment. A principle with regard to the occurrence of carbon fiber alignment is presented

Insights from tyrosinase into the impacts of modified morphology of calcium carbonate on the nacre formation of pearl oysters

Frontiers in Marine Science, 2022
Tyrosinase is a type-3 copper protein with six conserved histidine residues within the copper-binding sites. It participates in mollusk nacre formation.

Histological and Comparative Transcriptome Analyses Provide Insights Into the Immune Response in Pearl Sac Formation of Hyriopsis cumingii

Frontiers in Marine Science, 2020
Immune response plays an important role in the pearl sac formation and pearl quality. However, there is little knowledge about the mode and mechanism of the immune responses in the pearl sac formation of the pearl mussel Hyriopsis cumingii. In this study,
