The Subject

In dealing with the Inheritance of Glume-Length [Engledow(1)] there were encountered certain problems relating to metrical characters. As it appeared that these problems must attach to all genetic work upon a metrical basis, they were made the subject of a separate investigation. A simple account of some of the difficulties experienced in connection with Glume-Length Inheritance will serve to formulate the problems.

Zonna pellucidae can be develop as antigen potential candidates based on reversible immunocontraceptive vaccines. Immunogenic sites of bovine zonna pellucidae 3 (bZP3) could stimulated the presence of anti-bZP3 which be located on rabbit ZP and inhibit sperm-egg interaction on fertilization process. Purpose of this research is to detect spesific binding anti-bZP3 to rabbit oocytes using dot blotting and ELISA method. Sub cutan induction of bZP3 with Freund's adjuvant, CFA (Complete Freund's Adjuvant) for initial immunization and following by IFA (Incomplete Freund's Adjuvant) at the 14th day and 39th day. Control female rabbit injected by Tris-Cl buffer diluted in Freund's adjuvant without bZP3 antigen. Rabbit serum injected to rat for producing Rat Anti Rabbit Anti-bZP3. This research concludes spesific binding of anti-bZP3 with increasing purple colour on dot blotting methods. Anti-bZP3 increasing on 24th day and 31th day and still until 48th day. Measurement with ELISA methods showed increased titer on OD405. Highest titer showed on 31th day post immunization. Anti-bZP3 synthetized by bZP3 induced on rabbit detectable by immunohistochemistry methods on late primary oocytes, early secondary oocytes, growing secondary oocytes, and oocytes on de Graaf folicular phase.

Field Test Method

A field test is described for determination of 0.02 M CaC12 extractable ('soluble') aluminium in soils. The method uses a 5 min extraction (2 min shaking followed by 3 min settling period). An aliquot of extract is then added to the metallochromic reagent chrome azurol S, CAS (amber). Aluminium reacts rapidly with CAS in hexamine buffer (pH 4.9) to form a 1 : 1 complex, Al(CAS) (purple). Intermediate colours arise in solutions where CAS is partly converted to the aluminium complex. The developed colour may be compared visually (or spectrophotometricaliy in the laboratory) with standards. Alternatively the CAS concentration may be selected to give the purple colour at a predetermined concentration of aluminium in the extractant solution, corresponding to the toxicity threshold for a specific crop and soil. CAS-reactive Al (5 min extraction) was correlated with total Al (1 h extraction; AAS) soluble in 0.02 M CaCl2, by Alt = 1.62[CAS-Al]+0.5 for soils with Alt < 60 mg kg-1 (n = 22; r2 = 0.99).

Cultivated Barley

Hordeum vulgare subsp. spontaneum is the progenitor of cultivated barley (Hordeum vulgare L.). Domestication combined with plant breeding has led to the morphological and agronomic characteristics of modern barley cultivars. The objective of this study was to map the genetic factors that morphologically and agronomically differentiate wild barley from modern barley cultivars. To address this objective, we identified quantitative trait loci (QTLs) associated with plant height, flag leaf width, spike length, spike width, glume length in relation to seed length, awn length, fragility of ear rachis, endosperm width and groove depth, heading date, flag leaf length, number of tillers per plant, and kernel color in a Harrington/OUH602 advanced backcross (BC2F8) population. This population was genotyped with 113 simple sequence repeat markers. Thirty QTLs were identified, of which 16 were newly identified in this study. One to 4 QTLs were identified for each of the traits except glume length, for which no QTL was detected. The portion of phenotypic variation accounted for by individual QTLs ranged from about 9% to 54%. For traits with more than one QTL, the phenotypic variation explained ranged from 25% to 71%. Taken together, our results reveal the genetic architecture of morphological and agronomic traits that differentiate wild from cultivated barley.

The first reported phytochemical studies on two species of flowers in Australia enabled the identification of six secondary metabolites from Illawarra flame tree flower (Brachychiton acerifolius) and seven secondary metabolites from the flowers of the Alstonville (Tibouchina lepidota). Pelargonidin 3-(6-coumarylglucoside)-5-(6-acetylglucoside) was found to be responsible for the red colour of B. acerifolius, whereas malvidin 3-(coumarylglucoside)-5-(acetylxyloside) was responsible for the purple colour of (T. lepidota) flowers. (2S)-4,5-Dihydroxyflavanone 7-O-β-d-glucuronide methyl ester was isolated for the first time from B. acerifolius, and its absolute configuration was determined by circular dichroism spectroscopy. Some of the traditional uses of B. acerifolius could also be correlated with the known activity of the isolated metabolites.

This exhibit represents some portions of a study of the stomodaeal nervous system, neurosecretory cells, corpora allata, corpora cardiaca, and prothoracic gland cells in post-embryonic stages of Aedes aegypti (L.), the yellow fever mosquito. Some of these structures share the common property of being involved in the production of hormones.Mosquitoes were reared under standard conditions. Larvae, pupae and adults were fixed at timed intervals in histological fixatives. Sectioned specimens were stained in Gomori's aldehyde-fuchsin, Gomori's chrome-haematoxyh-phloxin and other stains. The aldehyde-fuchsin technique, which imparted a bright purple colour to neurosecretory material, was particularly useful. Vita1 staining with methylene blue was used to trace the stomodaeal nervous system

The characteristic purple colour formed by N-formyl-N′-2,4-dinitrophenyl-hydrazine in the presence of piperidine and acetone was made the basis of a new quantitative method for the determination of formyl groups. Samples containing N-formyl groups (up to 0·4μmole) are hydrazinolysed at 97–98° for 1hr. and are dinitrophenylated after the removal of excess of hydrazine. Interference from 2,4-dinitrophenylhydrazine is eliminated by subjecting the dinitrophenylated samples to chromatography on an alumina column. Interference arising from the formation of N-acetyl-N′-2,4-dinitrophenylhydrazine, when determining formyl groups in samples containing acetyl, can be avoided by a paper-chromatographic separation before analysis. A standard procedure is described. The method gives satisfactory results when applied to N-formyl-amino acids. Gramicidin, when analysed by this method, was found to contain 0·89 mole of formyl group/mole for a molecular weight of 1880. The method indicated the absence of formyl groups from lysozyme, a protein known not to contain such groups. Generally, the analytical values obtained by the method are within 100±4% of theory.

ABSTRACTA simple method to develop TiO2, Ag or Au-doped TiO2 thin films on cotton textiles for advanced applications, is reported. The homogeneous TiO2 thin films have been deposited on cotton textiles by using sol-gel method at low temperature (100° C), whereas Ag and Au nanoparticles were then deposited on the pre-existent TiO2 films by photoreduction. The Ag/TiO2 covered cotton fibres show multichromic behaviour (grey colour under visible light and brown colour upon ultraviolet light exposure) as well as photoactivity. The Au-TiO2 film coated the cotton textile produces a purple colour with excellent self cleaning properties. The original and treated fibres have been characterized by several techniques (SEM, HRTEM, FTIR, Raman, UV–vis spectroscopy and XRD).
