Wheat (Triticum aestivum L.) is one of the most significant MNK1 web staple crops worldwide, giving more than 20 calories and protein for humans. Increasing wheat yield is vital for global food and nutrition safety (FAO, http://faostat.fao.org). Wheat yield is composed on the variety of panicles per unit location, the number of grains per panicle and grain weight, and among which the grain weight has higher heritability and stability, with good prospective for improvement (Li et al., 2019b). In practice, attempts to boost grain yield via enlarging grain size/weight have constantly been impeded by the trade-off between grain weight and grain number. Rising grain weight devoid of changing grain number has turn out to be a major objective of high-yield wheat breeding (Nav1.6 Purity & Documentation Bustos et al., 2013). Consequently, increasing grain weight and understanding the mechanism underlying grain size/weight handle are pivotal to increase yield of wheat.Seed is composed of embryo, endosperm along with the seed coat in the maternal tissue, which collectively figure out the size and weight from the seed (Shewry et al., 2012). It was demonstrated that KLUH/CYP78A5, which encodes cytochrome P450 monooxygenase, plays an essential role in controlling grain size. In Arabidopsis, KLUH increases seed size by non-cell autonomously stimulating maternal integument cell proliferation (Adamski et al., 2009). The rice KLUH homolog OsCYP78A13 impacts seed size by way of regulating the balance of sources for cell among embryo and endosperm (Xu et al., 2015). In tomato, SiKLUH controls fruit weight by increasing cell layer and delaying fruit ripening, as well regulating plant architecture by adjusting the quantity and the length of branches (Chakrabarti et al., 2013). Previous studies in Arabidopsis recommend that CYP78A5 is involved in the production of downstream mobile signal molecule (Anastasiou et al., 2007). Even though KLUH has been shown to affect seed size in various species, you will find no reports of this gene2021 The Authors.

The molecular mechanism of KLUH controlling seed size remains elusive. Auxin, the first found plant growth hormone, plays a vital role in plant development and improvement, which includes cell proliferation and expansion in the cytological level, embryogenesis, apical dominance and flowering at the macroscopic level (Pagnussat et al., 2009; Sauer et al., 2013; Shimizu-Sato et al., 2009). Appropriately growing auxin can raise crop yield (Shao et al., 2017). Current research showed that increasing the expression of PLA1/CYP78A1 in maize and CYP78A9 in rapeseed can increase seed weight and yield by affecting auxin metabolism (Shi et al., 2019; Sun et al., 2017), but a current study in Arabidopsis showed that CYP78A5 mostly affects cytokinin as an alternative to auxin metabolism (Jiang et al., 2021
