Identification of calconectin, a calcium‐binding protein specifically expressed by the mantle of Pinctada margaritifera [PDF]

open access: yesFEBS Letters, 2006
Nacre or mother‐of‐pearl in the shell of Pinctada margaritifera is composed of 95–99% calcium carbonate and 1–5% organic matrix. In this study, we developed an original technique to characterize the genes differentially expressed in nacre‐forming cells (NFC) by combining suppression subtractive hybridization (SSH), to establish a cDNA subtractive ...

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples

open access: yesAdvanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Screening Relaxants for Efficacy and Effects on Growth for Greenlip Abalone, Haliotis laevigata Donovan

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Relaxants are used in abalone aquaculture to facilitate handling, transport and grading stock, with minimal injury, stress, immune suppression and mortality. Benzocaine has been commonly used as an abalone relaxant but negative behavioural responses to exposure have been observed, and in some countries it has a withholding period, precluding ...
