Six medicinal plants, namely Boerhavia diffusa L., Calotropis procera (Ait.) R. Br., Jatropha gossypifolia L., Leonurus sibiricus L., Plumbago zeylanica L. and Ricinus communis L. of Bangladesh having anticancerous properties were investigated with a view to knowing their seed germination time, rate and pattern. The minimum days taken for seed germination in B. diffusa, C. procera, J. gossypifolia, L. sibiricus, P. zeylanica and R. communis were 70, 9, 24, 75, 11 and 14, respectively. The maximum time (130 days) required for germination was observed in Leonurus sibiricus. The highest germination rate (100%) was observed in Plumbago zeylanica, while the lowest rate (10%) was found in Ricinus communis. Epigeal type of germination was noted in all the species employed.

This study aimed to determine flavonoids levels contained in each of jatropha plant samples to be used as an alternative affordable free radicals deterrent. The flavonoid content was analyzed using UV-Vis spectrophotometry. Stem of the three samples was extracted using HCl. The results showed that total flavonoids levels contained in each stem of Jatropha curcas L., Jatropha gossypifolia L., and Ricinus communis L. were 3.959 mg/L, 1.309 mg/L, and 0.083 mg/L, respectively.

Euphorbiaceae is an important family which contains numerous medicinal plants. Today estimate that most of the people in developing countries still relays on traditional medicine based largely on species of plants in human being and animals for their primary healthcare. The family Euphorbiaceae is one of the largest family of flowering plants comprising of plants with over 300 genera and 8,000 species. Acalyphaindica L, Euphorbia hirta L, Euphorbia thymifolia L, Croton bonplandianumbaill, Jatropha gossypifolia L, Ricinus communis L are important plants of this family because these plants have different compounds like alkaloids, flavinoids, steroids, saponin, phenolic compounds, fatty acid, esters, minerals etc that have showed different activitiesin humen being and animal.This study provides important data for identification of different plants in Euphorbiaceae family. Species of Euphorbiaceae are extensively used as remedies against several diseases and complaints such as cancer, diabetes, diarrhoea, heart diseases, hemorrhages, hepatitis, jaundice, malaria, ophthalmic diseases, rheumatism and scabies etc.

AbstractCastor (Ricinus communis L) is an ideal model species for sex mechanism studies in monoecious angiosperms, due to wide variations in sex expression. Sex reversion to monoecy in pistillate lines, along with labile sex expression, negatively influences hybrid seed purity. The study focuses on understanding the mechanisms of unisexual flower development, sex reversions and sex variations in castor, using various genotypes with distinct sex expression pattern. Male and female flowers had 8 and 12 developmental stages respectively, were morphologically similar till stage 4, with an intermediate bisexual state and were intermediate between type 1 and type 2 flowers. Pistil abortion was earlier than stamen inhibition. Sex alterations occurred at floral and inflorescence level. While sex-reversion was unidirectional towards maleness via bisexual stage, at high day temperatures (Tmax > 38 °C), femaleness was restored with subsequent drop in temperatures. Temperature existing for 2–3 weeks during floral meristem development, influences sexuality of the flower. We report for first time that unisexuality is preceded by bisexuality in castor flowers which alters with genotype and temperature, and sex reversions as well as high sexual polymorphisms in castor are due to alterations in floral developmental pathways. Differentially expressed (male-abundant or male-specific) genes Short chain dehydrogenase reductase 2a (SDR) and WUSCHEL are possibly involved in sex determination of castor.

Endophytic Bacterial Community

AbstractRhizosphere and root endophytic bacteria are crucial for plant development, but the question remains if their composition is similar and how environmental conditions, such as water content, affect their resemblance. Ricinus communis L., a highly drought resistant plant, was used to study how varying soil water content affected the bacterial community in uncultivated, non-rhizosphere and rhizosphere soil, and in its roots. Additionally, the bacterial community structure was determined in the seeds of R. communis at the onset of the experiment. Plants were cultivated in soil at three different watering regimes, i.e. 50% water holding capacity (WHC) or adjusted to 50% WHC every two weeks or every month. Reducing the soil water content strongly reduced plant and root dry biomass and plant development, but had little effect on the bacterial community structure. The bacterial community structure was affected significantly by cultivation of R. communis and showed large variations over time. After 6 months, the root endophytic bacterial community resembled that in the seeds more than in the rhizosphere. It was found that water content had only a limited effect on the bacterial community structure and the different bacterial groups, but R. communis affected the bacterial community profoundly.
