In contrast, plants carrying a dominant allele (I-) develop systemic necrosis and eventually die, and depending upon the presence of other recessive bc-genes plants develop vein necrosis (II bc-1 2 bc-1 2 ) or local lesions (II bc-u bc-u bc-2 2 bc-2 2 ).
The SRF expression pattern corresponds to the future intervein wing cells, with SRF absent in developing veins [8].
For instance, the relatively high levels of Vegf mRNA near veins correlate with high proliferation rates in developing veins (Fig. 2E).
Because PIN1, PIN5, PIN6, and PIN8 are all expressed in developing veins (Fig. 1), we asked whether these genes were expressed in the same vascular cells.
To test these possibilities, we expressed PIN6 or PIN8 by the promoter of the MONOPTEROS (MP) gene (AT1G19850) (MP::PIN6 or MP::PIN8)—highly active in developing veins [ 33] in the pin1; 6 background, and compared defects of MP::PIN6; pin1; 6 and MP::PIN8; pin1; 6 with those of pin1; 6 and pin1.
Auxin drainage by developing veins would lower auxin levels in the surrounding areas below those levels which inhibit growth [ 87, 88], growth would resume, and new fields of cells would be generated in which the whole process could be repeated [ 2].
Although the number of veins in a leaf is variable and it is unpredictable whether a developing vein will remain open at maturity [ 6, 7, 10, 12– 14], the cardinality and connectivity indices of vein networks in different populations of WT leaves grown in identical conditions were reproducible (Figs. 3, 6, 7 and 8).
Two patients had postoperative complications: 1 in the NACT group developed vein thrombosis in the low limbs after laparoscopic surgery and recovered after anticoagulant therapy, and 1 in the PST group had urinary retention after laparotomy and recovered a month after catheter insertion and long-term retention.
Experts suspect that certain people inherit a tendency to develop varicose veins.
