Outcome of UV-B exposure and induction of some chlorophyll phenodeviants in two important hepatoprotective ethnomedicinal wild plants.

Present piece of work has been performed with an aim to engender genetic variations in (Burm f.) Nees and L. since both plants own low or very poor genetic variations due to wild nature.

Rationale of Using Dynamic Imaging for Characterization of Suspicious Lung Masses into Benign or Malignant on Contrast Enhanced Multi Detector Computed Tomography.

Objectives: To assess the utility of dynamic imaging namely, wash-in and wash-out characteristics through multidetector contrast-enhanced computed tomography in differentiating benign and malignant pulmonary masses.

Materials And Methods: Seventy-three patients who were suspected to have malignant pulmonary mass on the basis of clinical symptoms and chest radiograph were included in the study. All the patients underwent multidetector computed tomography scanning, and three series of images were obtained for each patient-noncontrast, early enhanced, and 15 min delayed enhanced scans.

Genetic damage induced by a food coloring dye (sunset yellow) on meristematic cells of Brassica campestris L.

We have performed the present piece of work to evaluate the effect of synthetic food coloring azo dye (sunset yellow) on actively dividing root tip cells of Brassica campestris L. Three doses of azo dye were administered for the treatment of actively dividing root tip cells, namely, 1%, 3%, and 5%, for 6-hour duration along with control. Mitotic analysis clearly revealed the azo dye induced endpoint deviation like reduction in the frequency of normal divisions in a dose dependent manner.

Induced cytomictic diversity in maize (Zea mays L.) inbred.

Mutation breeding has been used for improving oligogenic and polygenic characters, disease resistance and quantitative characters including yielding ability. The cytological stability of maize inbred lines is an important consideration in view of their extensive use in genetics and plant breeding research. Investigation in Zea mays L.

Influence of heat stress on genome of grass pea (Lathyrus sativus L.).

Meiosis is an event of high evolutionary stability that culminates in a reduction of chromosome number. Several abiotic environmental factors such as heat may cause anomalies at genetic level that ultimately impair fertility of the plant. In the present study, the effect of heat stress on various morphological and cytological parameters has been studied in Lathyrus sativus.
