“…7), there was a sense amino acid mutation detected (14-threonine to serine). In insects, steroidogenic CYPs are products of the Halloween genes phantom (CYP306A1), disembodied (CYP302A1), shadow (CYP315A1) and shade (CYP314A1) and are responsible for the last 4hydroxylations in the pathway leading to 20E (Niwa et al 2004;Niwa et al 2005;Warren et al 2002),which are biochemically similar to one that yields 20E in crustaceans (Lachaise et al 1993). In D. melanogaster, mutations in these genes disrupt 20E production and cause the arrest of embryonic development and death.…”

“…The Y-organ, termed as the moulting gland or ecdysal gland, consists of paired organs of ectodermal origin in the penaeid shrimp's head region (Lachaise et al, 1993). The Y-organ plays a crucial role in the moulting and growth of crustaceans (Spindler and O'Connor, 1980;Chang et al, 1993;Chang, 1995;Huberman, 2000).…”

“…Moulting, being the indirect version of growth, the structural integrity of the Y-organ, which regulates the moulting process through the moulting hormone, is vital for the successful moulting and growth in penaeids. Because the Yorgan is ectodermal in origin (Spindler and O'Connor, 1980;Lachaise et al, 1993), it is logical to assume its susceptibility to WSSV infection. As this endocrine gland plays a major role in the moulting and growth of shrimps, we investigated the histopathology of Y-organ with respect to WSSV infection in Indian white shrimp F. indicus and to determine the physiological implications of WSSV infected Y-organ in shrimp.…”

Histopathology of Y-organ in Indian white shrimp Fenneropenaeus indicus, experimentally infected with white spot syndrome virus

et al. 2003

Histopathology of Y-organ (moulting gland) in Indian white shrimp Fenneropenaeus indicus was studied after challenging the shrimp with virulent white spot syndrome virus (WSSV). Histopathological investigation on the Y-organ collected from moribund shrimps revealed the presence of intranuclear basophilic inclusions, characteristic of WSSV. More than 70% of the Yorgan cells were infected, suggesting the degenerated state of the organ. The cellular integrity of the Y-organ was completely destroyed by the WSSV. Further, Y-organ tissue samples collected from all the 16 experimental shrimp were positive by one-step polymerase chain reaction (PCR), confirming severe WSSV infection. The infected Y-organ in F. indicus with majority of the organ cells observed in the lysed condition suggests a physiological dysfunction of the organ. In uninfected and healthy controls, the lobulated Y-organ showed closely packed normal cells with prominent nuclei and sparse cytoplasm. Physiological implication of a degenerated Y-organ in the moulting and reproduction of the penaeid shrimp is discussed. D

“…Inhibition of molting is thought to be due to a suppressive action of circulating MIH on ecdysteroid synthesis in the molting glands (Y-organs). The mechanism of this inhibitory action is not yet understood in detail (see [1][2][3] for reviews).…”

Molecular cloning of crustacean putative molt‐inhibiting hormone (MIH) precursor

et al. 1993

A cDNA encoding the complete precursor of the putative molt-inhibiting hormone (MIH) of the shore crab, Carcinus maenas, was isolated and sequenced. The precursor consists of a putative 35 amino acid signal peptide and the 78 amino acid mature MIH. The deduced MIH amino acid sequence is in complete agreement with the sequence previously determined by Edman degradation. In situ hybridization revealed MIH-expression in a subpopulation of large neurosecretory perikarya of the medulla terminalis X-organ in the eyestalk.
