Deposition Process of Polysaccharides with the Development of Japanese Walnut Xylem

Deposition Process of Polysaccharides with the Development of Japanese Walnut Xylem
オニグルミの木部形成にともなう木材多糖の絶対量の変化を薄層クロマトグラフィー・デンシトメトリーで調べた。すなわち分化中木部を形成層側から髄側へ順次分け取り, 種々の抽出処理をし酸加水分解した後, 中和・濃縮し, 薄層クロマトグラフィーで糖を分離した。そしてエチレンジアミン硫酸塩を噴霧し各糖のスポットの蛍光の強さを測定して定量した。セルロースはS_1形成期からS_2形成期まで継続的に堆積する。グルクロノキシランもセルロースとほぼ同様な堆積の仕方を示す。グルコマンナンはセルロースやグルクロノキシランの堆積よりもやや遅れ, S_2形成後期からS_3形成期にかけて堆積する。アラビノースやガラクトースは一次壁形成期に堆積するが二次壁形成期には壁に供給されないものと思われる。 Thin-layer ...

Rice Productivity in Saline–Alkaline Soils: Constraints, Microbiome‐Mediated Regulation and Management Strategies

Journal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
ABSTRACT Saline–alkaline soils are widespread and represent a particularly restrictive environment for rice, especially in arid and semi‐arid regions. These soils commonly combine elevated salinity with high pH, sodium‐related soil constraints and bicarbonate/carbonate accumulation, resulting in severe physicochemical and nutritional limitations. Under

Biochar and K‐fertigation modulate stomatal behaviour, ion homeostasis and water use efficiency in waxy maize seedlings under salt stress

Journal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
Efficacy of wheat straw biochar in alleviating salt stress under K‐fertigation via improved photosynthesis, water use efficiency and ion homeostasis in waxy maize. ABSTRACT K‐fertigation and soil amendment could ameliorate the adverse effects of saline stress on C4 crop physiology and performance, yet the underlying mechanisms remained largely elusive.

Drought‐Induced Anatomical Compensation Stabilizes Gas Exchange in Sorghum

Journal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
ABSTRACT Drought limits carbon gain in crops, yet the functional role of bulliform cells in regulating gas exchange and water‐use efficiency remains unclear. Here, we tested whether natural variation in bulliform size alters carbon assimilation rate and whole‐leaf water‐use efficiency in Sorghum bicolor.

Root Plasticity and Hormonal Regulation Shape Alfalfa Cultivar Responses to Drought and Waterlogging

Journal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
ABSTRACT Alfalfa (Medicago sativa L.) is a globally strategic forage legume whose productivity is increasingly threatened by climatic variability, particularly recurrent drought and flooding events. Although both stresses disrupt plant water balance, they impose contrasting physiological constraints that require distinct adaptive strategies.

Drought and salinity stress remodel Asian rice (Oryza sativa) leaf development through cell‐type‐specific regulatory programs

New Phytologist, Volume 252, Issue 4, Page 1376-1395, November 2026.
Osmotic stressors induce developmental and physiological changes in rice (Oryza sativa) seedlings, which are modulated by cell‐type‐specific gene expression and regulatory networks. We exposed plants to two levels of drought and salinity stress and measured the effects of these stressors on developing leaves by measuring physiological traits, ion ...

Forest under stress: responses and recovery of water relations across scales during the compound drought in summer 2022

New Phytologist, Volume 252, Issue 3, Page 1050-1064, November 2026.
A schematic showing the links of tree‐scale (root‐, stem‐, and leaf‐level) and ecosystem‐scale water relations during the CSAD at CH‐Lae. Summary The summer of 2022 was characterized by compound soil and atmospheric drought (CSAD; low soil water content, SWC, and high vapor pressure deficit, VPD) in Central Europe, threatening forest carbon ...

Evolution in arid environments: the role of betalains, succulence, and medullary bundles

New Phytologist, Volume 252, Issue 3, Page 1250-1268, November 2026.
Overview of the study system. Summary The flowering plant clade Caryophyllales includes many succulent species that grow in drought conditions. Many Caryophyllales species also have betalain pigmentation and medullary bundles, both of which have been linked to stress tolerance, albeit with less precise functional characterisation.

Functional memory of drought affects leaf chemical defenses and microbial interactions in aspen

New Phytologist, Volume 252, Issue 4, Page 1413-1431, November 2026.
Experimental design of the common garden study. Summary Drought is an important driver of tree mortality, but its long‐term impacts on trait expression remain poorly understood. Leaves are a key interface at which trees respond to abiotic stress, and foliar traits such as chemical defenses and microbial communities may play a role in determining post ...
