Dear Vasu Kuraparthy

Thank you for your invitation to present a talk at ICGI at PAG in San Diego 2027.

Time permitting, I may also add some other recent work.

The main part would be this recently published paper that has not yet been presented as a talk.

Abstract:

High yield is one of the most desirable traits in crops. A negative correlation between yield and other desirable traits in crops may be due to either pleiotropy or repulsive linkage. Multi-parent advanced generation inter-cross (MAGIC) populations create opportunities for novel combinations of alleles of genes from several parents to exist in one recombinant inbred line. Here, we describe the breaking of the repulsive linkage between yield (YLD) and cotton fiber strength (STR) at Chr. Ghi_A07:90 Mb in a Gossypium hirsutum L. MAGIC population. The loss of a PHL3-like gene (Ghi_A07G11906) may dampen the phosphate (Pi) starvation response and attenuate a reallocation of resources to root growth at the expense of vegetative and reproductive growth, and thus a reduction in yield. Targeted mutagenesis of transcription factors that modulate abiotic stress responses may be a generalizable strategy for yield improvement in farmed crops.
