Ethylene production is negatively associated with storage life in sand pear (Pyrus pyrifoliaNakai), particularly at the time of fruit harvest. 1-Aminocyclopropane-1-carboxylic acid synthase (ACS) is the rate-limiting enzyme in ethylene biosynthesisand is considered to be important for fruit storage life. However, the candidate ACS genes and their r...

... sand pear, all PprACSs contained the seven conserved regions of ACS (Figure 1) [23] and were located in 8 chromosomes unevenly: chromosomes 15 and 2 resided three genes, chromosomes 1 had two genes, and chromosomes 4, 6, 7, 8 and 14 only showed one gene ( Figure S2). Subcellular prediction results showed that all PpyACS proteins were localized in the chloroplast, except for typeⅡACS, which were cytoplasm-localized proteins. ...

... The localization of proteins in different organelles may be related to their function (Gao et al. 2019;Wang et al. 2017). Previous reports have indicated that ACS is localized in the cytoplasm or chloroplasts (Jakubowicz and Sadowski 2002;Van de Poel and Van Der Straeten 2014;Zhang et al. 2021), which was confirmed by our results on the subcellular location of ACSs in maize, rice and sorghum (Table 4 S). Interestingly, subcellular localization predictions showed that only SsACS2 was located in the nucleus and other SsACSs in chloroplasts (Table 1). ...
... The ACS multi-gene family synthesizes a series of peptidases that regulate ethylene synthesis pathways in plants under growth, development and stress conditions (Barry et al. 1996). Several investigations have revealed that type I was involved in ethylene biosynthesis Zhang et al. 2021). The expression of the type I member AtACS2 in Arabidopsis is associated with root growth and lateral root formation (Liang et al. homology with S. bicolor (Table 1), respectively. ...
... The expression of the type I member AtACS2 in Arabidopsis is associated with root growth and lateral root formation (Liang et al. homology with S. bicolor (Table 1), respectively. This finding was consistent with the results of studies in A. thaliana (Yamagami et al. 2003) and other higher plants (Lee et al. 2018;Zhang et al. 2021), indicating that there was great differentiation within the members of the ACS gene family and high conservation among the same type of ACSs. ...
Sugarcane (Saccharum spp.) is economically important in China. Ethylene is an important factor in regulating plant growth and sugar accumulation in sugarcane. 1-Aminocyclopropane-1-carboxylic acid synthase (ACS) is a rate-limiting enzyme in ethylene biosynthesis. However, knowledge of the ACS gene family of Saccharum is limited. In this study, we aimed to identify and analyze ACS genes in the genome of Saccharum. Bioinformatic analyses were performed to identify differences between the ACS sequences of Saccharum and homologous gene sequences of plants. The results showed that there were four ACS genes in the genome of Saccharum, and the phylogenetic tree revealed that the proteins encoded by these genes were similar to ACS isozymes with ACS activity in other plants. Evolutionary analyses suggested that the S. spontaneum ACS gene family may have expanded via segmental duplication events under purifying selection. Expression pattern analyses showed that the Saccharum ACS gene family was differentially expressed. ACS2 and ACS3 may be involved mainly in the development of various tissues during the vegetative growth stage and may be involved in the low-nitrogen response in sugarcane. These results provide relevant information to help determine the functions of the ACS genes in Saccharum, particularly the functions in regulating ethylene stimulation of abiotic stress and sugar productivity.
