Changes in the LH-cells of the anterior pituitary in relation to the reproductive cycle in the male Scotophilus heathi (Horsfield, 1831) are described. Immunocyto- chemical studies of the pituitary suggested two annual peaks of LH accumulation and release each associated with a period of active spermatogenesis and testosterone secretion. Further, in vitro study showed differences in testicular responsiveness to LH stimulation during November (a period of active spermatogenesis) and December (winter dormancy). Present study further showed that FSH is also capable of stimulating androgen secretion from the testis. Testicular FSH responsiveness varies from recrudescence to winter dormancy and this may be responsible for maintaining high circulating androstenedione production in S. heathi during this period.

The superficial ulnar artery (SUA) is a rare anatomical variant that usually arises either in the axilla or the arm and runs a superficial course in the forearm, enters the hand, and participates in the formation of superficial palmar arch. During the routine dissection of cadavers in the department of anatomy, whilst preparing the specimen for medical students, an unusual bilateral branch of the axillary artery was found in one of the cadavers: a rare variant of the artery known as SUA, which originates from the 2nd part of the axillary arteries of both sides. The SUA is a known anatomical variant, but the bilateral high origin from the 2nd part of the axillary artery is extremely unusual. Its occurrence is of great clinical importance to the surgical and radiological departments. (Folia Morphol 2012; 71, 1: 48–51)

Diploid wheat, Triticum monococcum L. (einkorn) is an ideal plant material for wheat functional genomics. Brittle culm mutant was identified by screening of the ethyl methane sulphonate-treated M2 progenies of a T. monococcum accession pau14087 by banding the plant parts manually. The brittle culm mutant with drooping leaves, early flowering, reduced tiller numbers and susceptible to lodging had also exhibited brittleness in all plant parts than the wild-type parents. Comprehensive mechanical strength, histological, biochemical, scanning electron microscopy, and Fourier transform infrared spectroscopy analyses of brittle culm mutant supplemented and complemented the findings that the mutant had defective cellulose biosynthesis pathway and deposition of cell wall materials on secondary cell wall of mechanical tissues. Microscopic studies demonstrated that the decrease in cellulose contents resulted in the irregular cell wall organization in xylem vessels of leaf vascular bundles. To map the brc5 mutant, mapping populations were developed by crossing the brittle culm mutant with wild Triticum boeoticum acc. pau5088, having non-brittle characters. The brittle culm mutation was mapped between SSR markers, Xcfd39 and Xgwm126 on 5AmL chromosome of T. monococcum, with genetic distances of 2.6 and 4.8 cM, respectively. The brc5 mutant mapped on 5AmL, being distinct from a previously mapped brittle culm mutant in wheat, has been designated as brc5. The work on fine mapping and map-based cloning of brc5 gene regulating synthesis and deposition of cellulose on the secondary cell wall is in progress.

High temperature reduces the growth and yield of most of the agriculturally important crops. Elicitors have been reported to modulate the thermotolerance of crops under abiotic stresses. Here, we studied the effect of salicylic acid (SA) on thermotolerance level of C306 (thermotolerant) and PBW343 (thermosusceptible) wheat cultivars grown under heat stress. Pilot experiment confirmed spraying of 100 mM SA prior to heat stress (38 C, 2 h) as the most effective treatment. Numerous protein spots were observed in C306 under SA + HS compared to PBW343 during post-anthesis stage by 2-DE. Differentially expressed proteins were identified as signaling molecule, heat-responsive transcription factors (HSFs) and heat shock proteins (HSPs) using MALDI-TOF–TOF/MS analysis. Abundance of transcripts of HSFs, HSPs, CDPK, SOD, RCA, etc. was observed in C306 in response to SA + HS, as compared to PBW343. C306 showed better accumulation of transcript of SAGs, osmolyte and total antioxidant capacity under SA treatment compared to PBW343. SA was observed to reduce the detrimental effect of HS on soluble starch synthase (SSS) activity as well as synthesis of starch granules in both the cultivars.
