Can anyone suggest which physiological and genetic factors/genes affect the number of siliques in Arabidopsis thaliana?
Hi, Navjyoti, This is a very interesting quetion, indeed! There are a lot of factors whch may affetc such numbers. Among physiological one can consider minerak niútrrient balance during flowering and during silique maturation, you can increase a number of siliques by adding additinal nutrients during flowering, Amohg genetic factors alteration in the horminal balance is the most important. So, any genes involve in tze regulation of the local hormone distribution have a primary importance in the regulation of the silique number.

Dear Navjyoti,
The alterative to these suggestions is that you might be looking at a meiotic mutant, under these circumstances you get tie reduced sliques iwht no seeds in , or some mutants we find that they have.a reduced number of seeds present and that leads to accompanying reduced silque length.
