A photo of a cyst nematode's head viewed through a high-power microscope shows its esophageal glands, which produce effectors it uses to infect host plants. The image was digitally edited to highlight ...

Ferns switch between male and hermaphrodite forms, a process driven by chemical signals. Research shows the plant hormone auxin is key, triggering new growth centers when a male signal is absent.

Female moths avoid laying eggs on stressed plants that emit ultrasonic sounds. Instead, they choose silent, healthy plants.
