The ubiquitous phosphoenolpyruvate carboxylase enzymes in plants play pivotal role during carbon metabolism in photosynthesis, physicochemical processes, and tolerance to various abiotic or chemical stresses. We are presenting a bioinformatics identification of PEPC gene family in tomato and its phylogenetic classification into PTPC and BTPC sub families. Tomato PEPC genes are distributed in four different chromosomes with a unique motif and gene structure that strengthen their classification into two sub families. Identification of twelve different cis-regulatory elements related to abiotic and exogenous phytohormones showed their diverse role. Moreover, RNA-seq and qRT-PCR based tissues specific analysis revealed their role in its growth and development. In tomato, PEPC genes exhibited a diverse temporal expression under salt, cold and exogenous phytohormones. For an instance, SlPEPC1, SlPEPC4, and SlPEPC5 was upregulated under salt, drought, ABA, and JA in shoots. While, SlPEPC3, SlPEPC4, and SlPEPC5 was induced in root tissues upon exposure to drought, cold, and GA. Similarly, the enzyme activity of tomato PEPC was significantly upregulated under all these stresses but peaked under salt and IAA in roots and under GA in leaves. All tomato PEPC predicted in cytoplasm and the transient expression assay validate it. Our study insight into unique features of PEPC gene family in tomato and may sever as foundation for functional their studies.

Biofilm formation of a nitrogen-fixing cyanobacterium Anabaena torulosa with a beneficial fungus Trichoderma viride (An-Tr) was examined under laboratory conditions. A gradual enhancement in growth over A. torulosa alone was recorded in the biofilm, with 15-20% higher values in nitrogen fixation, IAA and exopolysaccharide production illustrating the synergism among the partners in the biofilm. To investigate the role of such biofilms in priming seed attributes, mesocosm studies using primed seeds of two maize inbred lines (V6, V7) were undertaken. Beneficial effects of biofilm (An-Tr) were recorded, as compared to uninoculated treatment and cyanobacterial consortium (Anabaena-Nostoc; BF 1-4) at both stages (7 and 21 DAS, days after sowing) with a significant increase of more than 20% in seedling attributes, along with 5-15% increment in seed enzyme activities. More than three- to fivefold higher values in nitrogen fixation and C-N mobilizing enzyme activities, and significant increases in leaf chlorophyll, proteins and PEP carboxylase activity were observed with V7-An-Tr biofilm. Cyanobacterial inoculation brought about distinct changes in the soil phospholipid fatty acid profiles (PLFA); particularly, significant changes in those representing eukaryotes and anaerobic bacteria. Principal component analyses illustrated the significant role of dehydrogenase activity and microbial biomass carbon and distinct elicited effects on soil microbial communities, as evidenced by the PLFA. This investigation highlighted the promise of cyanobacteria as valuable priming options to improve mobilization of nutrients at seed stage, modulating the abundance and activities of various soil microbial communities, thereby, enhanced plant growth and vigour of maize plants.
