Identification of ACC Synthetase Genes in Saccharum and their Expression Profiles During Plant Growth and in Response to Low-nitrogen Stress

Exploring Ethylene-Related Genes inCannabis sativa: Implications for Sexual Plasticity

“…The presence of ACS and ACO are critical to ethylene biosynthesis, but the number of genes in each family can vary between species. For example, in Pyrus ussuriensis L. (pear) 13 ACS and 11 ACO genes have been identified (Yuan et al ., 2020), in Zea mays L. 5 ACS and 15 ACO genes have been identified, in rice 6 ACS and 9 ACO genes, and in tomato there are 9 ACS and 7 ACO genes (Houben & Van de Poel, 2019; Wu et al ., 2022). The importance of having multiple functionally redundant ethylene biosynthesis genes has been demonstrated in multiple plants, with studies showing ACS and ACO genes are expressed at different levels and in different tissues as a function of the plant organ’s needs and developmental stage (van de Poel et al ., 2012; Van de Poel et al ., 2014).…”

“…For example, in corn (Zea mays L.) 5 ACS and 15 ACO genes have been identified, in rice (Oryza sativa L.) those numbers are 6 and 9 respectively and in tomato (Solanum lycopersicum L. Karst. ex Farw) there are 9 ACS and 7 ACO genes (Houben & Van de Poel, 2019;Wu et al, 2022). The importance of having multiple functionally redundant ethylene biosynthesis genes has been demonstrated in multiple plants, with studies showing ACS and ACO genes are expressed at different levels and in different tissues as a function of the plant organ's needs and developmental stage.…”
