Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

open access: yesJournal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

Sucrose supply from leaves is required for aerenchymatous phellem formation in hypocotyl of soybean under waterlogged conditions [PDF]

open access: yesAnnals of Botany, 2018
Soil waterlogging often causes oxygen deficiency in the root systems of plants and severely inhibits plant growth. Formation of aerenchyma - interconnected spaces that facilitate the movement of gases between and within the aerial and submerged parts of plants - is an adaptive trait for coping with waterlogged conditions.

Bark anatomy of Polylepis (Rosaceae): a loose stratified phellem instead of the lenticels?

open access: yesBotanica Pacifica, 2023
Bark structure of Polylepis incana (Sanguisorbeae, Rosaceae) is described and compared with that in related genera Cliffortia and Leucosidea. Tribe Sanguisorbeae shows an extraordinary diversity of bark abscission patterns. The outermost bark portions are peeling off along the non-conducting secondary phloem (Leucosidea, Cliffortia ruscifolia), or ...

The Aerenchymatous Phellem of Lythrum salicaria (L.): a Pathway for Gas Transport and its Role in Flood Tolerance [PDF]

open access: yesAnnals of Botany, 2002
While the importance of cortical aerenchyma in flood tolerance is well established, this pathway for gaseous exchange is often destroyed during secondary growth. For woody species, therefore, an additional pathway must develop for oxygen to reach submerged tissues.

Structure and formation of phellem of Betula maximowicziana

IAWA Journal, 2018
Betula species have phellems with distinctive features such as stratification into thin paper-like layers, which are easily split in the tangential direction, and linear lenticels. We aimed to clarify the structure and development of the characteristic phellems of B. maximowicziana.

Silencing against the conserved NAC domain of the potato StNAC103 reveals new NAC candidates to repress the suberin associated waxes in phellem [PDF]

open access: yesPlant Science, 2020
Both suberin and its associated waxes contribute to the formation of apoplastic barriers that protect plants from the environment. Some transcription factors have emerged as regulators of the suberization process. The potato StNAC103 gene was reported as a repressor of suberin polyester and suberin-associated waxes deposition because its RNAi-mediated ...
