Arabidopsis
during flower development, floral organs such as sepals, petals, stamens, and carpels developed normally. However, the development of pollen inside the anther was disrupted in a stage-specific manner, with floral stage 9 primordia failing to produce any pollen grains. Morphological analyses suggested that heat shock causes a failure of separation of pollen mother cells followed by microspore differentiation and/or inhibition of male meiotic processes. Heat shock also caused sterility in floral stage 12 flowers but the sterility was due to the failure of pollen release from the pollen sacs.
