这篇综述系统梳理了植物气腔（aerenchyma）形成机制的研究进展，重点探讨了裂生型（schizogeny）、溶生型（lysigeny）和扩生型（expansigeny）三种形成途径，揭示了活性氧（ROS）、果胶修饰和程序性细胞死亡（PCD）等关键分子事件在气腔网络构建中的作用，为理解植物适应低氧（hypoxia）和水涝胁迫的 ...

本研究针对气候变化导致的水分可利用性突变问题，探究了排水型 (A502、CMG1590等)与淹水型 (Pampa)水稻基因型在50%田间持水量 (50% FC)胁迫下的生理与解剖适应性。通过生长参数、气体交换、叶根解剖等分析，发现Pampa (淹水型)与A502 (排水型)通过增加根皮层通气组织 (aerenchyma)、维持根系生物量和光合 ...

Lysigenous aerenchyma mainly form in plants growing in wet areas but can also be found in plants in dry or nutrient deficient places. The researchers found that low concentrations of essential ...

Leaf structural characteristics and gas-exchange measurements were used to determine whether photosynthetic tissue of Typha latifolia L. (cattail) utilized CO2 from the aerenchyma gas spaces, part of ...

Under well-drained (aerobic) conditions, wetland plants form aerenchyma constitutively. Auxin signaling regulates programmed cell death (PCD) during constitutive aerenchyma formation in the roots ...

Aerenchyma formation can help crops cope with these environmental stresses. However, it is not commonly observed in non-wetland species like wheat and maize, which are staple food crops in certain ...

Transcription factor bHLH121 regulates root cortical aerenchyma formation in maize. Proceedings of the National Academy of Sciences, 2023; 120 (12) DOI: 10.1073/pnas.2219668120 ...

Wetland plants have a high tolerance against flooding due to the formation of “lysigenous aerenchyma,” air channels that help transfer gases to the submerged roots. These channels also help ...

To allow oxygen to flow down into the roots and methane to flow out of the soil, the rice plant uses aerenchyma, a spongey tissue that acts a little bit like a chimney. Methane is produced by bacteria ...
