Korrekt müsste es heissen: „Silphie ist eine ökol. vorteilhafte Alternative zur Maissorte PM Paolo“. Ob das generell auf Mais zutrifft, lässt sich aus dieser Studie mit nur einer Maissorte nicht sagen.

Finally, we identified a gene that regulates lateral root density in hybrids depending on the genetic constitution of its regulatory eQTL. 7/7

Importantly, SPE genes were mainly regulated by heterozygous eQTL, underscoring the importance of heterozygosity for the regulation of dominant loci, thus reconciling the competing genetic hypotheses of overdominance (heterozygote advantage) and dominance (complementation) to explain heterosis. 6/7

Single parent expression (SPE) complementation, an expression pattern in which genes are expressed in only one parent and in the hybrid, consistent with dominance, explained up to 29% of heterotic variance for root traits. 5/7

In general, these partial hybrids expressed more genes than their parental lines (IBM-RIL and B73 or Mo17). 4/7

We generated backcrosses of 112 intermated B73xM17 recombinant inbred lines to their parents B73 and Mo17, thus generating a set of partial hybrids with an average heterozygosity of 50%. 2/7

no, maybe around 5. Mainly from Pakistan, India, African countries.
