How Hormones and MADS-Box Transcription Factors Are Involved in Controlling Fruit Set and Parthenocarpy in Tomato

Abstract: Fruit set is the earliest phase of fruit growth and represents the onset of ovary growth after successful fertilization. In parthenocarpy, fruit formation is less affected by environmental factors because it occurs in the absence of pollination and fertilization, making parthenocarpy a highly desired agronomic trait. Elucidating the genetic program controlling parthenocarpy, and more generally fruit set, may have important implications in agriculture, considering the need for crops to be adaptable to climate c… Show more

“…In this study, GH3.1 may be an important part in balancing the auxin synthesis and metabolism to ensure a fruit set in "R35-P" under any favorable or unprofitable conditions. Overall, these studies revealed that parthenocarpy can be achieved by manipulating auxin action at different levels, by acting on its biosynthesis, signaling cascade, and transport, corroborating the crucial role played by this hormone in the control of a fruit set (Molesini et al, 2020). Taken together, these results indicated that auxins played a pivotal role in controlling the fruit set of "R35-P."…”

“…LAX2 related to IAA transport with a possible role in the regulation of auxin influx ( Pattison and Catalá, 2012 ). As IAA-amido synthetase, GH3 can promote an IAA conjugation to amino acids to maintain auxin homeostasis ( Molesini et al, 2020 ). In this study, GH3.1 may be an important part in balancing the auxin synthesis and metabolism to ensure a fruit set in “R35-P” under any favorable or unprofitable conditions.…”

“…Besides, boron deficiency can affect pollen germination, pollen tube growth, fruit set, and seed formation, thereby inhibiting reproductive growth ( Alva et al, 2015 ). Previous studies on seedless phenotype were principally focused on other species, such as Arabidopsis ( Goetz et al, 2007 ), tomato ( Klap et al, 2017 ; Takisawa et al, 2018 ; Molesini et al, 2020 ), grapevine ( Malabarba et al, 2017 ; di Rienzo et al, 2021 ; Li et al, 2021 ), citrus ( Zhang et al, 2018 ; Liang et al, 2020 ), eggplant ( Chen et al, 2017 ), sugar apple ( Lora et al, 2011 ), and pear ( Wang et al, 2021a , b ).…”

“…The authors found two independent mutations in MADS-box transcription factor SHELL , a homolog of the MADS-box gene SEEDSTICK (also known as AGAMOUS-Like 11, AGL11 ), which acts on the ovule identity and seed development in Arabidopsis ( Singh et al, 2013 , 2020 ). In addition, MADS-box genes have also been reported to be implicated in pollen fertilization and the development of seedless fruits ( Klap et al, 2017 ; Takisawa et al, 2018 ; Tang et al, 2019 ; Wei et al, 2019 ; Molesini et al, 2020 ). MADS-box gene AGL11 has been proposed as the key gene responsible for triggering the seedless phenotype ( Ocarez and Mejía, 2016 ).…”

“…A peculiar and distinctive phenotype of the tomato Sltpd1 mutants is the formation of seedless fruits (parthenocarpic). Parthenocarpy, the formation of fruits in the absence of pollination and fertilization, is often the consequence of the precocious activation of molecular events normally triggered by these processes (Molesini et al, 2020). Also, it could be achieved by external applications of different hormones or growth regulators (Vivian-Smith and Koltunow, 1999).…”
