Studies on the Pollen Morphology of 4Th Genus Farsatia (Brrassicaca
INT. J. BIO. BIOTECH., 2(2): 289-293, 2005. PALYNOLOGICAL STUDY OF SOME GENERA OF BRASSICACEAE (SAMERARIA, SAVIGNYA, TAUSCHERIA, TETRACME, TORULARIA, TURRITIS) FROM PAKISTAN Rehana Khan Department of Botany, Federal Urdu University of Arts, Sciences and Technology, Karachi, Pakistan. ABSTRACT Pollen morophology of 10 species belonging 5 genera of the family Brassicaceae from Pakistan has been examined by light microscope. Pollen grains are usually radially symmetrical, sub-prolate to prolate or oblate-spheroidal, tricolpate rarely 4-6 colpate. Sexine thinner and thicker than nexine. Tectum reticulate with more or less than nexine. Tectum reticulate with more or less regular pattern. Key Words: Palynological study of some genera of Brassicaceae from Pakistan. INTRODUCTION Brassicaceae is a cosmopolitan family of about 350 genera and 3000 species occurring mainly in north temperate zone particularly in the Mediterranean region (Mabberly, 1987). In Pakistan 92 genera and 250 species have been reported (Jafri, 1973). Oil is extracted from the seed, of Brassica species. Many crucifers are cultivated as ornamental like Aubrita (Aubrietia). Chiguriaena (1973) examined the pollen morphology of the family Brassicaceae in relation to taxonomy. Javed and Naqshi (1976) also utilized pollen data in the classification of the family Brassicaceae. Pollen morphology of the family Brassicaceae has been examined by Erdtman (1952), Sharma and Nair (1973), Carter et al. (1975), Moore and Webb (1978). The most comprehensive studies of Brassicaceae pollen is that of Rollins and Banerjee (1979). Khan (2003, 2004) studied the pollen of the genus Arabidopsis and Alyssum belong to the family Brassicaceae from Pakistan. The present investigation is based on the pollen morphology of 10 taxa representing 6 genera of the family Brassicaceae viz., Sameraria, Savignya, Tauscheria, Tetracme, Torularia, Turritis by light microscope. -

Tracking the Evolutionary History of Development Genes: Implications for the Diversification of Fruits and Flowers in the Brassicaceae and Cleomaceae by Kelsey Brock A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Plant Biology Department of Biological Sciences University of Alberta © Kelsey Brock, 2014 Abstract Flowers of Brassicaceae are remarkably similar across all species, whereas their fruits vary in almost all conceivable traits, particularly in the tribe Brassiceae. In contrast, Brassicaceae’s sister family, Cleomaceae, exhibits substantial variation in flowers but are more uniform in their fruits. These diversifications represent either variation in pollen transfer or seed dispersal, which are important reproductive traits that likely affect survival. The history of both families involves four shared polyploidy events as well as each independently experiencing separate additional polyploid events. Thus, these families offer an excellent opportunity to investigate whether additional genetic materials from polyploid events are correlated with the evolution of novel flower and fruit morphologies. Based on knowledge from model plants, FRUITFULL (FUL), a fruit development gene important for dehiscence (fruit opening), and TEOSINTE BRANCHED 1/ CYCLOIDEA/ PROLIFERATING CELL FACTOR 1 (TCP1), a gene known to affect floral symmetry, were chosen as candidate genes to examine the evolutionary history and retention of gene duplicates alongside morphological novelty in Brassicaceae and Cleomaceae. A gene phylogeny of FUL was generated to determine if fruit diversity in the tribe Brassiceae (Brassicaceae) could be correlated with FUL copy number, structure, or evolutionary history. Similarly, TCP1 was assessed to identify differences in gene evolutionary history between the florally diverse Cleomaceae and the florally uniform Brassicaceae.
