Chloroplast movement is important for leaf growth and the timing of reproduction

Chloroplast movement allows plants to optimize light absorption for photosynthesis and to avoid photoinhibition. Howard et al. report that Arabidopsis mutants, growing for six weeks under natural conditions in the field, produced fewer leaves, bolted later, and produced fewer fruits when their chloroplasts were unable to move. The specific effects on growth and reproduction depended on the growth conditions, highlighting the importance of investigating mutants in different environments. Since the study used a range of mutants, it was possible to pinpoint which of the observed effects may be due to pleiotropic effects of the mutations and which were exclusively caused by a lack of chloroplast movement, underscoring the importance of chloroplast movement for plant growth and reproduction, especially under natural conditions.

叶绿体运动对叶片生长和繁殖时机很重要

叶绿体的移动使植物能够优化光吸收，以进行光合作用并避免光抑制。霍华德等。报告说拟南芥这些突变体在田间的自然条件下生长了六个星期，其叶绿体无法移动时，叶片较少，随后栓接，果实较少。对生长和繁殖的具体影响取决于生长条件，突显了研究不同环境中突变体的重要性。由于该研究使用了一系列突变体，因此有可能查明哪些观察到的效应可能是由于突变的多效性所致，而哪些仅是由于缺乏叶绿体运动引起的，强调了叶绿体运动对植物生长和生长的重要性。繁殖，特别是在自然条件下。
