Highlights•Tree stems are more than a conduit for phloem C transport; they are a significant
C sink.•Isotopes demonstrate most phloem-transported C exchanges with NSC stored in …

Storage is a fundamental process that allows organisms to meet variable demand for 22
resources during their development and buffer environmental fluctuations in resource 23 …

Carbohydrates play a central role in plant functioning because they are building blocks and
energy carriers for plant metabolic processes. Because plants are sessile organisms and …

Nonstructural carbohydrate (NSC) storage plays a critical role in tree function and survival,
but understanding and predicting local NSC storage dynamics is challenging because NSC …

Non‐structural carbon (NSC) storage (ie starch, soluble sugras and lipids) in tree stems play
important roles in metabolism and growth. Their spatial distribution in wood may explain …

The usage of nonstructural carbohydrates (NSCs) to indicate carbon (C) limitation in trees
requires knowledge of the minimum tissue NSC concentrations at lethal C starvation, and …

A conceptual understanding on how the vegetation's carbon (C) balance is determined by
source activity and sink demand is important to predict its C uptake and sequestration …

Storage is a characteristic feature of most plants, particularly perennials, and the subject has
been thoroughly reviewed according to its chemistry and physiology (9, 40, 59, 80, 133 …

Stoichiometry of leaf macronutrients can provide insight into the tradeoffs between leaf
structural and metabolic investments. Structural carbon (C) in cell walls is contained in lignin …

Plants store large amounts of non‐structural carbohydrates (NSC). While multiple functions
of NSC have long been recognized, the interpretation of NSC seasonal dynamics is often …
