Fig. 4: dcl5-1 anther fertility is temperature sensitive.
From: Dicer-like 5 deficiency confers temperature-sensitive male sterility in maize
Three sets of dcl5-1 and sibling dcl5-1//Dcl5 plants grown in greenhouses with differing temperature regimes: 28/22 °C, 26/20 °C, or 23/20 °C (day/night). a–c Temperatures were recorded every 2 h for 60 days (gray dots, average in red; day/night indicated as white or black, below). d–f Heterozygous dcl5-1//Dcl5 siblings were fully fertile under all three regimes. g–i dcl5-1 plants in the restrictive regime (g) were completely male sterile, while those in permissive conditions were partially (h) or fully (i) fertile. Images were taken at 60 ± 3 days after planting (DAP) (top row), 70 ± 2 DAP (middle row), and 71 ± 3 DAP (bottom row); the pace of tassel development is temperature-dependent and full anther exertion occurs at different days after planting, for example f was photographed on the first day of anther exertion, a seven-day process (see “Methods” section). The scale bar in d is approximate and pertains to all tassel images.
