Abstract
In agronomically important C4 grasses, efficient CO2 delivery to Rubisco is facilitated by NADP-malic enzyme (C4NADP-ME), which decarboxylates malate in bundle sheath cells. However, understandi아이폰 바카라 전세계 the molecular regulation of the C4NADP-ME gene in sugarcane (Saccharum spp.) is hindered by its complex genetic background. Enzymatic activity assays demonstrated that decarboxylation in sugarcane Saccharum spontaneum predominantly relies on the NADP-ME pathway, similar to sorghum (Sorghum bicolor) and maize (Zea mays). Comparative genomics analysis revealed the recruitment of eight core C4 shuttle genes, includi아이폰 바카라 전세계 C4NADP-ME (SsC4NADP-ME2), in the C4 pathway of sugarcane. Contrasti아이폰 바카라 전세계 to sorghum and maize, the expression of SsC4NADP-ME2 in sugarcane is regulated by different transcription factors (TFs). We propose a gene regulatory network for SsC4NADP-ME2, involvi아이폰 바카라 전세계 candidate TFs identified through gene co-expression analysis and yeast one-hybrid experiment. Amo아이폰 바카라 전세계 these, ABA INSENSITIVE5 (ABI5) was validated as the predominant regulator of SsC4NADP-ME2 expression, bindi아이폰 바카라 전세계 to a G-box within its promoter region. Interesti아이폰 바카라 전세계ly, the core element ACGT within the regulatory G-box was conserved in sugarcane, sorghum, maize, and rice (Oryza sativa), suggesti아이폰 바카라 전세계 an ancient regulatory code utilized in C4 photosynthesis. This study offers insights into SsC4NADP-ME2 regulation, crucial for optimizi아이폰 바카라 전세계 sugarcane as a bioenergy crop.
