Growth difference of planted from different provenances in Maoer Mountain, China.

In order to analyze the growth pattern of tree height of planted and screen the provenances with fastest growth, we grouped the provenances using the differences in tree height, diameter at breast height (DBH) and volume of timber of 234 individuals of planted from 26 provenances in Maoershan Experimental Forest Farm. We constructed the growth equation for tree height by combining the base models of Gompertz, Korf, Richards, Logistic, and Schumacher, and then selected the optimal one. We introduced the prove-nance grouping as a dummy variable into the base model, and evaluated the optimal tree height growth equation by a comprehensive evaluation of the model according to the coefficient of determination (), the root-mean-square error (RMSE), the Akaikei Information Criterion (AIC), and the model's predictive precision ().

Mettl3-mA-Creb1 forms an intrinsic regulatory axis in maintaining iNKT cell pool and functional differentiation.

N-methyladenosine (mA) methyltransferase Mettl3 is involved in conventional T cell immunity; however, its role in innate immune cells remains largely unknown. Here, we show that Mettl3 intrinsically regulates invariant natural killer T (iNKT) cell development and function in an mA-dependent manner. Conditional ablation of Mettl3 in CD4CD8 double-positive (DP) thymocytes impairs iNKT cell proliferation, differentiation, and cytokine secretion, which synergistically causes defects in B16F10 melanoma resistance.
