Auxin Distribution in Fruits and Its Significance in Fruit Development

Fruits: A Developmental Perspective

“…If ovules do not develop seeds in part of a fruit, lopsided fruits are formed in which normal and retarded organ development coincide closely with the presence or absence of seeds, respectively (Roberts, 1946;Nitsch et al, 1960). A positive correlation also exists between the number of developing seeds and sustained fruit growth (Gustafson, 1939a;Hobson and Davies, 1970). Thus, the genetic parameters that control the final size and weight of the fruit can be influenced by the number of developing seeds (Nitsch, 1970).…”

Changes in tomato ovary transcriptome demonstrate complex hormonal regulation of fruit set

“…The embryo or surrounding tissue possibly produces the first signals that stimulate growth of the placental tissue and the ovary wall (pericarp). Gustafson (1936Gustafson ( , 1939 showed that auxin application can stimulate seedless (parthenocarpic) fruit growth in some species, and the role of auxin in fruit development has been firmly established by many other researchers (Nitsch et al ., 1960;Sastry & Muir, 1963;Mapelli et al ., 1978;Mapelli & Lombardi, 1982;Alabadí et al ., 1996;Wang et al ., 2005). An important function in fruit set has also been ascribed to gibberellins (GAs), whose application to tomato ( Solanum lycopersicum ) flowers also leads to parthenocarpic fruit growth (Asahira et al ., 1968;Bünger-Kibler & Bangerth, 1982;Sjut & Bangerth, 1982;Alabadí et al ., 1996;Fos et al ., 2000).…”

Interacción de Giberelinas y Auxinas en la fructificación del tomate.

“…También es sabido que existe una correlación entre el número de semillas en desarrollo y el crecimiento del fruto (Gustafson, 1939;Hobson y Davies, 1970;Varga y Bruinsma, 1986).…”
