Is there anyone who is working on lintless mutants and ethylene production in cotton ?
in our group no one is working on cotton but i think some one in our department is working on BT-Cotton. Dr. Shafaqat Ali can tell you in details.
Why we have to do that?
Fuzzless (short lint attached to seed) is controlled by recessive allele.
However, that allele may link with some inferior quality.
Since higher ethylene production in cotton is expected during reproductive growth phase, and it is essential for lint formation, I was wondering if lintless mutants produce any ethylene or not.
Although literature available shows inability of the lintless mutants to produce ethylene in developing ovules but no data is available on plants
Yes, I have worked on lint less cotton. I tried to culture in MS media using various combination of phytohormones and partially I was succeeded. I do not have at present any lint less material (infect I am interested to work on this). I have also evaluated endogenous phytohormones in various cotton varieties including IAA, PAA, GA ABA and ethylene also but in normal seed and fiber. we have data on ABA in abnormal seed and fiber but not of ethylene.
Thanks Vrinda Thaker, Did you study phyto-hormones in growing plants under normal conditions? which plant part? any variation in the concentrations of these phyto-hormones in normal and lintless mutants. I am currently working on lintless mutants and observed no variation in ethylene production from different plant tissues of lintless and normal plants, although some data indicated lintless mutants are not producing any ethylene.
I have not worked on ethylene, so I don't know. But ABA concentration is more in abnormal seeds of cotton specially growing in late season. The ratio of GA and IAA is important for better fiber growth and ratio of GA and ABA is important for seed growth.
Thanks Vrinda, I think I should look more details of these phyto-hormonal changes for further studies.
