Nuclear integration of MYB36 and APX-1 genes impart heat tolerance in wheat.

Funct Integr Genomics

October 2024

Sanya Institute of Breeding and Multiplication, School of Tropical Agriculture and Forestry, Hainan University, Sanya, China.

Elevated temperatures during grain filling stage, exceeding the optimal range by 3-4 °C, not only results in a substantial yield reduction in wheat by 10-50% but activates disease and insect infestation. In this research, we introduced heat-tolerant MYB36 and APX-1 gene cassettes into wheat, employing an efficient Agrobacterium mediated transformation protocol, demonstrating higher transformation efficiency. The study encompassed the assembly of MYB36 and APX-1 gene cassettes, and confirmation of gene products in Agrobacterium, followed by the transformation of the MYB36 and APX-1 genes into wheat explants.

Previous studies have shown that subcutaneous adipose tissue is an important energy supply organ for chicks before and after birth, except yolk. So far, the significance of large deposits of subcutaneous adipose tissue in chicks is unclear. Therefore, this study takes the information interaction between adipocytes and macrophages as the starting point to explore whether adipocytes and macrophages could participate in adipose tissue fibrosis, angiogenesis, adaptive thermogenesis and other related functions in a specific metabolic environment.

Tropical oceans are the main global water vapor and latent heat sources, but their responses to radiative forcing remain unclear. Here, we investigate oceanic moisture dynamics of the western tropical Pacific (WTP) over the past 210,000 years through an approach of planktonic foraminiferal triple oxygen isotope (Δ'O). The Δ'O record is dominated by the precession cycles (~23,000 years), with lower values reflecting higher humidity in concert with higher Northern Hemisphere summer insolation.
