Control of Plant Growth and Defense by Photoreceptors: From Mechanisms to Opportunities in Agriculture

Ronald Pierik et al.

Summary: Plants detect and respond to the proximity of competitors using light signals perceived by photoreceptor proteins. Different photoreceptors help plants optimize their developmental configuration and resource allocation patterns in the canopy by controlling major regulatory nodes for growth and development. Understanding these mechanisms is important for breeding programs and manipulating light environments in agriculture.

RELATIVE COMPETITIVENESS BETWEEN MAIZE HYBRIDS AND WILD POINSETTIA

Leandro Galon et al.

Summary: This study evaluated the relative competitive ability of maize hybrids in the presence of wild poinsettia through replacement series experiments. The results showed that both maize and wild poinsettia were negatively affected by competition for the same resources, with only hybrids 'Nidera' and 'Velox' being more competitive than wild poinsettia.

WATER DEFICIT ON GROWTH AND PHYSIOLOGICAL INDICATORS OF Bidens pilosa L. AND Bidens subalternans DC

Marcio Alexandre Moreira de Freitas et al.

Summary: The stress caused by soil water deficit inhibits plant growth and understanding the behavior of weed species under water stress conditions is crucial for effective control strategies. Two experiments were conducted to evaluate the effects of water deficit on physiological and growth indicators of two weed species. Results showed that Bidens plants can tolerate low water availability conditions, but high water stress can lead to plant death, particularly with B. subalternans showing higher sensitivity.
