The isotopic composition of atmospheric carbon dioxide (δ 13 C atm ) provides insights into the terrestrial carbon cycle. However, long‐term global δ 13 C atm maps with both high spatial resolution and continuous temporal coverage remain scarce. Here, we present a new global terrestrial dataset of monthly δ 13 C atm isoscapes from 2001 to 2020 at 0.05° spatial resolution, developed by integrating in situ observations with opti...

Key message HanMYB1 was found to play positive roles in the modulation of anthocyanins metabolism based on the integrative analysis of different color cultivars and the related molecular genetic analyses. Abstract As a high value ornamental and edible crop with various colors, sunflowers ( Helianthus annuus L.) provide an ideal system to understand the formation of flower color. Anthocyanins are major pigments in higher plants...
