Fruit respiration: putting alternative pathways into perspective
New Phytologist, Volume 250, Issue 1, Page 54-73, April 2026.Summary Over the past century, research has significantly advanced our understanding of fruit respiration, from (eco)physiological processes to molecular mechanisms. This review focuses on the functional relevance and regulatory roles of mitochondrial alternative respiratory pathways (ARPs) during fruit growth and ripening.

Rhizobial motility preference in root colonization of Medicago truncatula
New Phytologist, Volume 250, Issue 1, Page 547-562, April 2026.Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.

Shuitu Baochi Xuebao, 2008 主要研究了石菖蒲、泽泻、菖蒲、黄花鸢尾、千屈菜这5种常见水生观赏植物对城市污水的生理生化变化,分别在第5 d,10 d和15 d对植物叶片膜脂过氧化(MDA、电导率)、体内保护系统酶(CAT、POD)、非酶类(游离Pro)及根系活力等抗性生理指标进行测定,探讨植物抗污水逆境的能力。研究结果表明,不同植物适应污水环境能力不同。其中,黄花鸢尾在污水处理下的抗逆性最强,与对照相比其电导率和丙二醛含量变化不大,而一些植物在实验初期受到污水胁迫,电导率和丙二醛含量较对照有上升的现象;同时 ...

A PLETHORA3/7 transcription factor shapes cucumber shoot architecture
New Phytologist, Volume 250, Issue 1, Page 230-245, April 2026.Summary PLETHORA transcription factors (PLTs) are master regulators of plant development. Loss of shoot meristematic PLTs leads to reduced phyllotactic regularity and robustness in Arabidopsis and increased inflorescence branching in tomato. Whether these factors have similar functions in other species is not known.

Shuitu Baochi Xuebao, 2016 在植物生长旺盛期，采用材料试验机测定3～4 a生柠条、沙柳、沙棘、白沙蒿在1～4 mm径级范围内的侧根分支处、相邻上级直根的抗拉力与抗折力，研究4种植物根系易受损的外力类型。结果表明：同径级条件下，柠条和沙柳的侧根分支处、相邻直根均表现为抗拉力小于抗折力，而沙棘和白沙蒿侧根分支处和相邻直根均表现为抗拉力大于抗折力。侧根分支处抗拉强度和抗折强度分别为：柠条(23.70±3.97)＜（33.66±7.74) MPa，沙柳(14.86±1.28)＜（17.31±1.91) MPa，沙棘(10.61±2.40)＞

Microclimate drives demographic compensation in a narrow endemic tropical species
New Phytologist, Volume 250, Issue 1, Page 166-180, April 2026.Summary Demographic compensation occurs when reductions in some vital rates are offset by increases in others, allowing populations to maintain similar performance across varying environments. This mechanism may help explain species' ecological distributions and range limits, yet its role at microenvironmental scales remains poorly understood.

Shuitu Baochi Xuebao, 2019 磷在土壤中易被固定沉淀，在植物磷利用率低的情况下，过度施肥会造成磷肥浪费，可能通过地表径流、地下水溶解等方式，造成水体富营养化产生面源污染，对人类生产生活造成较大影响。丛枝菌根真菌（arbuscular mycorrhizal fungi，AMF）和植物结合所形成的共生菌根可以显著增强植株对磷的吸收利用。通过AMF可以提高宿主植株对磷的吸收转运的特性，从AMF促进植株对磷元素的摄取机制、AMF促进植物磷摄取分子机理 ...

New Phytologist, Volume 250, Issue 2, Page 934-948, April 2026.Summary Wind‐driven plant movement generates rapid light fluctuations (windflecks), which can impact canopy photosynthesis. Targeting crop photosynthesis in dynamic light provides a potential path towards boosting yield. Here, we quantified how plant architecture and biomechanics modulate such windflecks across 10 high‐yielding cultivars of winter ...
