Comparative Transcriptome Sequencing To Determine Genes Related To The Nucellar Embryony Mechanism In Citrus, Özhan Şi̇mşek, Di̇cle Dönmez, Si̇nan Eti̇, Turgut Yeşi̇loğlu, Yildiz Kaçar

Several citrus varieties produce apomictic seeds by the nucellar embryony (NE) mechanism. Nucellar embryos are created from nucellus tissue and have an identical genetic constitution to the mother plant. Nucellar embryony is known to be an unusual feature of seed production in many citrus cultivars. The term "NE" refers to the development of identical embryos from the maternal tissue known as the nucellus surrounding the embryo sac. The authors aimed here to detect differentially expressed genes involved in the NE mechanism. Orlando tangelo (OT), producing apomictic seeds, and a clementine mandarin, Algerian tangerine ranch selection (AT), known as monoembryonic, were …

This study was carried out to determine the amount of apomictic fruit set in 10 Turkish walnut (Juglans regia L.) genotypes in 2001, 2002 and 2003. Yalova-1, Şebin, Bilecik, KR-1, KR-2, Şen-2, 07-KOR-l, Tokat-1, Kaman-1 and Kaman-5 cultivars and selections were used in the experiment. Female flowers were bagged and/or pollinated with pollen of the apple cv. 'Golden Delicious' (Malus x domestica Borkh.), and the apomictic fruit set was determined 8 weeks after anthesis. The percentage of apomictic fruit set without pollination ranged from 0.5% to 1.6% in 5 walnut genotypes, namely Yalova-1, Bilecik, 07-KOR-l, Tokat-1 and Kaman-1, in the …
