Goldenhar syndrome (GS) is a well-recognised condition characterised by variable degree of uni- or bilateral involvement of craniofacial structures involving first and second branchial arches manifesting ocular and auricular anomalies and also vertebral defect. This syndrome presents at birth and its exact aetiology is still unknown. The affections of the neural crest cells may have some role in the multiple malformations of the GS. We present a teenaged female case who attended the Orthopaedic Outpatient Department to receive handicapped certificate in Bankura Sammilani Medical College and Hospital. She had multiple skeletal abnormalities, which included hemifacial microsomia, vertebral malformations in the form of scoliosis, distorted pelvis, but the most striking feature was the absence of thumb and aplasia of radius of left side. She did not suffer from any ocular or auricular abnormalities, neither from any cardiological, urogenital or gastroenteric ones. Radial defects associated with GS might represent a subset within this spectrum. Our case probably belongs to this subset, therefore is a very rare one. (Folia Morphol 2013; 72, 4: 362–365)

A little known species of snake eel, Ophichthus lithinus (Jordan et Richardson, 1908), is reported for the first time from the east coast of India, Bay of Bengal based on two specimens 632 and 720 mm in total length, collected respectively at Digha, West Bengal and Kalpakam, Tamil Nadu, India. This is the first attempt to provide a detailed description of the species from the Indian Ocean. The presently reported findings constitute an extension of the known distributional range of this species from the Western Pacific to the eastern coast of India.

First records of: viper moray, Enchelynassa canina (Quoy et Gaimard, 1824); vermiculated blenny, Entomacrodus vermiculatus (Valenciennes, 1836); cardinalfish, Apogon fleurieu (Lacepède, 1802); and orangelined cardinalfish, Archamia fucata (Cantor, 1849) in the waters along the east coast of India are herewith documented. This record increases the knowledge on the richness of the Indian marine reef-associated fauna and may suggest a range extension of the geographical distribution of the mentioned species from the western Indian waters to east coast of India.

A specimen of garden eel, Heteroconger tomberua Castle et Randall, 1999, was collected from the traveling water screen of sea water cooling system of the Madras Atomic Power Station (MAPS), Kalpakkam located along the east coast of India. Previously, H. tomberua was recorded in Fiji, Pacific Ocean. The presently reported record greatly extends the fish range to the Indian Ocean and constitutes a new addition to the ichthyofauna of India. The described specimen of H. tomberua, with its total length 55.9 cm, seems to be the largest ever found.

Abiotic stresses such as drought and high salinity unfavorably affect the growth and productivity of crop plants. Therefore, the development of stress-tolerant crops is essential for the affected cultivable areas. It has been shown in the current study that the overexpression of stress-responsive NAC1 (SNAC1) transcription factor (TF) significantly increases salinity and drought tolerance in a farmer-popular high-yielding, transgenic rice. The indica rice variety BRRIdhan 55, which was poorly responsive to tissue culture was transformed with the SNAC1 TF from the rice landrace Pokkali by the in planta method. Addition of acetosyringone in the Agrobacterium suspension and coculture media increased previously reported transformation efficiencies by four-folds. Integration of foreign genes into the genome of transgenic plants was confirmed by genespecific PCR and Southern blot analysis. The level of transgene expression (SNAC1) was also quantified by realtime PCR. Genetic segregation ratio for T1 progenies was calculated and found to follow the law of Mendelian inheritance. Phenotypic screening was conducted at T2 and T3 seedling stages where the transgenic lines exhibited much better tolerance compared to their control nontransgenic plants at 120 mM (NaCl) salt as well as drought stress implemented by withholding water for 20 days.

West Bengal is one of the most populated states of India. The residents of the state are mostly dependent on agriculture and allied activities for their livelihood. Livestock also provide economic support and food security to them. A survey in veterinary hospitals and cattle farms of Murshidabad, Nadia, Malda and Birbhum district of West Bengal indicated the frequent occurrence of bacterial, fungal, viral and protozoan diseases in cattle. Some of these diseases like cryptosporidium diarrhoea, ringworm and salmonelliasis are zoonotic in nature and thus, are easily transmitted to human. The frequency of diseases increases during rainy season. Infection of alimentary canal and pneumonia are more common in calves whereas, arthritis is more common in male. Most of the common diseases of cattle like anthrax, rabies, foot and mouth disease, bovine tuberculosis, etc., can be prevented by proper vaccination. Some of these diseases can easily be diagnosed by modern techniques like ELISA, PCR, etc. But lack of veterinary hospitals, socio-economic backwardness and misconception have prevented easy diagnosis and treatment of these common diseases. Common antibiotic like kanamycin, antifungal drugs and antitoxins are generally applied to treat these diseases. Further, maintenance of proper hygiene, isolation of diseased animal, regular check-up and vaccination can prevent easy transmission of the diseases and thus, will put a check on livestock damage.

The upsurge in global temperatures and the increasing threat of salinity are adversely affecting rice productivity in the southern coastal lands of Bangladesh. A Bangladeshi rice landrace Horkuch, adapted to these saline conditions, has long been cultivated by farmers in this region. To understand the trend and heritability of its tolerance traits, a reciprocal population of Horkuch with the high-yielding sensitive rice IR29 was generated for mapping of quantitative trait loci (QTLs) at both seedling and reproductive stages in an F2:3 strategy using double-digest restriction associated DNA. We found 29 QTLs and some QTL clusters containing survival and yield-related QTLs showing pleiotropic effects over some phenotypes. We advanced the generation up to F₅ to obtain homozygosity and our current work is aimed at confirming these mapped QTLs at F₅ by salt stress physiological tests at both stages as well as DNA markers linked to these QTLs. We confirmed SES QTL (survival of seedling under stress) associated with SSR marker RM25789 and two QTL clusters at chromosome 10 and 11 associated with RM26964 and RM27027, respectively. One cluster harbored yield-related filled grain number, filled grain weight, total grain number, harvest index, ionic balance and transpiration-related total sodium, total potassium and stomatal conductance QTLs. The other cluster contained total grain weight, filled grain weight and seedling root relative water content QTLs. We identified some individuals based on their physiological performance under stress as well as the presence of QTLs associated with some SSR markers that can be used for breeding and production of highly salt-tolerant cultivars with high yield.

The vacuolar Na⁺/H⁺ antiporter is known to alleviate saline stress by sequestering Na⁺ in both wildtype Arabidopsis and rice and when over-expressed in many transgenic plants. Here we report on the effect of the NHX1 transgene on the salt tolerance properties it confers to a rice landrace and a commercial cultivar suitable for the dry winter season, but which suffers loss due to seasonal stresses, particularly in the coastal areas. The Nipponbare Na⁺/H⁺ antiporter 1.9 kb cDNA was cloned into pCAMBIA1305.1 under the control of the CaMV35S promoter and transformed into tissue-culture-responsive rice landrace Binnatoa (BA). The best-expressing transgenic line at T2 was found to be significantly tolerant at the seedling stage and was advanced to T3. The transgene was then transferred to the tissue-culture recalcitrant farmer-popular commercial rice genotype, BRRIdhan 28 (BR28) by crossing. The data generated both from semi-quantitative RT-PCR and western blot hybridization revealed that the transgene showed similar expression in the crossbred BR28 plants and BA transgenic line. Comparative stress tolerance tests, however, revealed that the BR28 crossbred lines were significantly less tolerant than its transgenic parent BA at both seedling and reproductive stages. A single successful transgenic event may therefore not show the same performance in the recipient genetic background, if introgressed by crossing.
