The heart, an ancient organ and the first to form and function during embryogenesis, evolved
by the addition of new structures and functions to a primitive pump. Heart development is …

Plants have evolved a variety of mechanisms to adapt to N starvation. NITRATE
TRANSPORTER2. 4 (NRT2. 4) is one of seven NRT2 family genes in Arabidopsis thaliana …

Serum response factor (SRF) regulates transcription of numerous muscle and growth factor-
inducible genes. Because SRF is not muscle specific, it has been postulated to activate …

Plant phosphate transporters (PTs) are active in the uptake of inorganic phosphate (Pi) from
the soil and its translocation within the plant. Here, we report on the biological properties …

Plant phosphate (Pi) transporters mediate the uptake and translocation of this nutrient within
plants. A total of 13 sequences in the rice (Oryza sativa) genome can be identified as …

Iron is essential for both plant growth and human health and nutrition. Knowledge of the
signaling mechanisms that communicate iron demand from shoots to roots to regulate iron …

The tissue‐restricted GATA‐4 transcription factor and Nkx2‐5 homeodomain protein are two
early markers of precardiac cells. Both are essential for heart formation, but neither can …

The high affinity nitrate transport system (HATS) plays an important role in rice nitrogen
acquisition because, even under flooded anaerobic cultivation when NH4+ dominates …

Following gastrulation and establishment of the three embryonic germ layers, the first
definitive organ to form in the embryo is the heart, whose morphogenesis, growth, and …

Heterozygous mutations in the cardiac homeobox gene, NKX2-5, underlie familial cases of
atrial septal defect (ASD) with severe atrioventricular conduction block. In this study, mice …
