Introduction

Prof. Chinta Sudhakar is a faculty with the Department of Botany, Sri Krishnadevaraya University, Anantapur since 1987. Currently serving as Professor and Coordinator of Department of Biotechnology.

Prof. Chinta Sudhakar received his Ph.D. from the Sri Krishnadevaraya University, Anantapur, in 1990 for the thesis entitled “Influence of salt stress on seed germination and seedling growth of some pulse crops”.

Prof. Chinta Sudhakar has been teaching advanced subjects like Plant Physiology, Plant Biochemistry, Environmental Plant Physiology, Plant Molecular Biology, Plant biotechnology and Plant Genetic Engineering for M.Sc., students.

Prof. Chinta Sudhakar’s long range research aim is to develop simple biochemical and genetic markers to screen and evaluate stress tolerant crop species of local importance.  His research interests include  study the effects of environmental stress factors such as drought, salinity and heavy metals  on locally important crops, horsegram, greengram, foxtail millets, mulberry and groundnut, understanding  biochemical and molecular strategies of plants under stress conditions and elucidation of the molecular mechanisms of stress tolerance of plants.   His research has been funded by UGC, DST, APNLBTP and DST-DAAD and DBT.

Prof. Chinta Sudhakar has been awarded DBT National Associateship during 1993-94 and worked with Prof. H.S. Savithri, Department of Biochemistry, Indian Institute of Science, Bangalore for one year on Isolation and purification of stress induced proteins in foxtail millets. Later he visited UK under Commonwealth Staff Academic Programme in 1998-99 and worked on QTLs of rice salt tolerance at University of Sussex, Brighton for one year.

Prof. Chinta Sudhakar has been awarded  DST DAAD PPP exchange programme for a period of three years (2002-2005).  Under this programme, he and three of his research students have visited IPK, Gatersleben, Germany twice in a year for a period of one month and three months respectively, to work on proteome analysis of barley.

Prof. Chinta Sudhakar has recently been awarded DBT Overseas Associateship, Govt of India and visited University of California, Riverside for 6 months (January – June 2006) worked in the laboratory of Prof. T.J. Close on cowpea and barley genomics.

Total grants brought to the department of Botany and Biotechnology  by Prof. Chinta Sudhakar is  about 1.25 Crores. This has contributed enormously to the existing research facilities of these departments and facilitated to undertake research work in the field of Plant Molecular Biology and Genetic Engineering.

Currently, Prof. Chinta Sudhakar is working on “Expression of stress responsive genes in groundnut (Arachis hypogaea L.) under water stress” in collaboration with University of Agricultural Sciences, Bangalore funded by APNLBT Programme, IPE, Hyderabad with a budget  Rs. 80 lakhs funded by APNLBTP for the period 2001-2006.

Prof. Chinta Sudhakar has been guided 7 Ph.Ds, so far and all  students were awarded reputed  International  fellowships like Alexander Van Humbolt, DAAD of Germany, and Korean Science and Technology fellowships and all students are well placed at USA, Germany, South Korea, ICGEB New Delhi and in National Universities.

Prof. Chinta Sudhakar has been associating with Department of Biotechnology as Additional Coordinator and as Coordinator for the last five years and contributed significantly in strengthening the academic activities of the department and in executing the APNLBT project support for M.Sc programme. He organized a three-week Refresher course on “Plant Biotechnology” for the college teachers and a 2-day National symposium on “Biotechnology – Recent Trends and Perspectives” and a Public Debate on “Biotechnology - Promise or Peril” funded by APNLBTP during 2005-2006.

The facilities created from Prof. Chinta Sudhakar research grants has been extended to give practical exposure to M.Sc students and Research students from sister departments too.
