    Differential action of Hg2+ and Cd2+ on the phycobilisomes and chlorophyll a fluorescence, and photosystem II dependent electron transport in the cyanobacterium Anabaena flos-aquae (1993)

    Notes: Abstract The effect of equimolar concentrations of Hg2+ and Cd2+ on the whole cell absorption spectra, absorption spectra of the extracted phycocyanin (PC) and fluorescence emission spectra of phycobilisomes (PBS) was investigated in the cells of Anabaena flos-aquae. The PC component of the PBS was found to be extremely sensitive to the Hg2+ rather than the Cd2+ ions. Further, the results showed that Hg2+ and Cd2+ induced decrease in the rate of Hill activity (H2O - DCPIP) was partially restored by the electron donor NH2OH, not by the diphenyl carbazide. Similarly, chlorophyll a fluorescence emission in the presence of metals showed that addition of NH2OH could effectively reverse the metal induced alterations in the fluorescence emission intensity. These results, together, suggested that Hg2+ and Cd2+ caused damage to the photosystems (PS) II reaction center. However, a relatively higher stimulation of the chlorophyll a emission at 695 nm with a red shift of 4.0 nm in the presence of Hg2+, and Cd2+ induced preferential decrease in the emission intensity at 676 nm as compared with the peak at 695 nm were indicative of the differential action of Hg2+ and Cd2+ on the PS II.

    Effect of signal-modulated optical radiation on the characteristics of a Modfet (1993)

    Notes: Abstract The effect of signal-modulated optical radiation on the characteristics of a GaAlAs/GaAs MODFET has been studied analytically. It is found that the offset voltage increases with modulation frequency and the effect of frequency is negligible above 5 MHz. The drain-source current decreases with increase in signal frequency at a constant radiation flux density, doping concentration and drain-source voltage. Studies on sheet concentration and transconductance also show that the signal frequency has a significant effect upto a certain modulation frequency (≲5 MHz) above which the effect of frequency is insignificant.

    Inheritance of the dwarf plant type in blackgram (Vigna mungo (L.) Hepper) (1985)

    Notes: Summary The inheritance of the dwarf plant type was studied in blackgram (V. mungo (L.) Hepper). ‘Type 9’ has erect plant type with normal internode length. The mutant line, ‘EMSD’ has reduced internode length. The F1, F2 and F3 generations of a cross between ‘Type 9’ and ‘EMSD’ and its reciprocal were studied. The extreme dwarf plant type appeared to be governed by a single recessive gene, dw 1 dw 1 with no cytoplasmic effect.

    Inheritance of spontaneous male sterility in peas (1995)

    Notes: Abstract A plant with a mutant phenotype was observed in a ‘Longittee’ cultivar. The plant was late in maturity, had white-translucent anthers, and was male sterile. The inheritance of this mutant was studied in a cross involving the mutant and the mother parent and their F1, F2, F3 and BC1F1 generations. The results suggested that the sterile character was genetic and due to a recessive gene.

    Notes: Abstract  A male-sterile plant was observed in the UPAS-120 cultivar of pigeonpea (Cajanus cajan). The plant was about 5–7 days late-flowering and had white translucent anthers with complete pollen sterility. The inheritance of this spontaneous male sterility was studied in a cross involving the mutant and fertile UPAS-120, including their F1, F2, BC1F1 and BC2F1 generations. The results suggested that the male sterility was genetic and due to a recessive gene.
