Table 2. Description of important up regulated genes in GD plants and their functions.

Gene ID	Name	Function	Log Fold Change	Reference (related to function)
AT5G13630	Magnesium chelatase	Such enzymes are involved in Mg+2 insertion in protoporphyrin during chlorophyll biosynthesis.	1.32	Mochizuki et al., 2001
AT3G56940	Putative dicarboxylate diiron	Involved in chlorophyll biosynthesis.	1.4	Kauss et al., 2012

AT3G60130	Beta glucosidase 16	It is involved to provide intermediates during cell wall development such as lignification.	1.1	Sing, Verma & Kumar, 2016
AT2G18700	Trehalose phosphatase/synthase	This gene encodes a protein which is putatively involved in trehalose biosynthesis, which is also involved in osmotic regulation during stress.	1.93	Ponnu, Wahl & Schmid, 2011
AT1G60140	Trehalose phosphate synthase	This gene encodes a protein which is putatively involved in trehalose biosynthesis, which is also involved in osmotic regulation during stress	1.44	Ponnu, Wahl & Schmid, 2011
AT1G23870	Trehalose -6-phosphatase synthase	This gene encodes a protein which is putatively involved in trehalose biosynthesis, which is also involved in osmotic regulation during stress	1.41	Ponnu, Wahl & Schmid, 2011
AT5G55700	Beta amylase 4	This gene encodes a protein which is involved in starch breakdown and localized in chloroplasts.	1.1	Thalmann et al., 2019
AT2G13360	Alanine: glyoxylate aminotransferase	Involved in photorespiration that performs transamination of glyoxylate.	1.03	Liepman et al., 2019
