Background:Land use change plays a vital role in global carbon *** land use change impact on soil carbon stock is crucial for implementing land use management to increase carbon stock and reducing carbon ***,the objective of our study was to determine land use change and to assess its effect on soil carbon stock in semi-arid part of Rajasthan,*** temporal satellite data of Pushkar valley region of Rajasthan acquired on 1993,2003,and 2014 were analyzed to assess land use *** trading of land use was depicted *** organic carbon(SOC)stock was calculated for soil to a depth of 30 cm in each land use type in 2014 using field data *** SOC stock for previous years was estimated using stock change *** effect of land use change on SOC stock was determined by calculating change in SOC stock(t/ha)by deducting the base-year SOC stock from the final year stock of a particular land use ***:The total area under agricultural lands was increased by 32.14%while that under forest was decreased by 23.14%during the time period of 1993–*** land use change shows that in both the periods(1993–2003 and 2003–2014),7%of forest area was converted to agricultural land and about 15%changes occurred among agricultural *** 1993–2003,changes among agricultural land led to maximum loss of soil carbon,i.e.,4.88 Mt C and during 2003–2014,conversion of forest to agricultural land led to loss in 3.16 Mt ***:There was a continuous decrease in forest area and increase in cultivated area in each time *** use change led to alteration in carbon equity in soil due to change or loss in ***,we can conclude that the internal trading of land use area during the 10-year period(1993–2003)led to net loss of SOC stock by 8.29 Mt ***,land use change during 11-year period(2003–2014)caused net loss of SOC by 2.76 Mt *** should be made to implement proper land

In the present study two phytocystatins (thiol protease inhibitors) have been isolated and purified to homogeneity form Catharanthus roseusby a simple two step procedure using ammonium sulphate fractionation and gelfiltration chromatography on Sephacryl- *** two inhibitors were named as CRCI and CRCII (Catharanthus roseuscystatin I and II). CRCI and CRCII were purified with a fold purification of 1333.3, 1348.5 and percent yield of 18.18 and 16.35% respectively. The molecular weight of purified phytocystatins were 19.1 kDa and 16.9 kDa respectively, as determined by SDS-PAGE and mass spectrometry. Effect of denaturants like ureaon CRCI and II was analysed by Fluorescence spectroscopy. Results suggest an unfolding of CRCI and II. FTIR results show that structurally CRCI is different from CRCII. Hydrophobic interactions are observed over a longer timescale (5 - 150 min). Furthermore, fluorescence spectroscopy results show quenching of fluorescence intensity of CRC I and II, although to different extent, due to perturbations of the environment of aromatic residues in the protein. Both the cystatins showed strong inhibitory/antibacterial activity against E. coliand S.
