Etude expérimentale en cartographie de la végétation par télédétection

open access: yesCybergeo, 2015
The purpose of this study is to evaluate the potential of aerial and satellite imageries of high spatial resolution for large scale vegetation mapping on Brittany, Normandy and Pays de la Loire regions at 1/25 000. Different types of images (BDORTHO® IRC,

ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

open access: yesAdvanced Science, EarlyView.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

Effet des fertilisants de l’agro-industrie dans l’évolution de la végétation aquatique envahissante sur la lagune de Ono, sur le littoral est de la Côte d’Ivoire [PDF]

open access: yesRevue de Géographie Tropicale et d’Environnement
La lagune Ono connait une eutrophisation importante marquée par la présence des plantes aquatiques envahissantes. Cette eutrophisation résulte de pratiques agro-industrielles dans son bassin versant. Ce cours d’eau est en constante pollution par les agro-

Optimal Grazing Exclusion Duration to Enhance Soil Carbon Sequestration in Degraded Grasslands

open access: yesAdvanced Science, EarlyView.
Across China, grazing exclusion reaches the national mean soil organic carbon recovery benchmark sooner in high‐MAP regions (> 500 mm), but recovery is much slower where MAP < 300 mm. Scaling this strategy to 70% of China's degraded grasslands would sequester about 1.52 Pg of soil carbon over 10 years—roughly 17% of annual global fossil‐fuel emissions.

Maize Anther Development Involves Translated Open Reading Frames From 3′ Untranslated Regions

open access: yesAdvanced Science, EarlyView.
This study examined the translation activity across ten stages of maize anther development, integrating transcriptome and small‐peptide data. It linked mutations in translated 3' ORFs to anther sterility, exemplified by Zm00001eb417050_3' ORF (known as APV1). In addition, the data indicated that maize anthers could assimilate CO2 through the stomata in

Narcissus dubius, Narcisse Douteux [PDF]

open access: yes, 2018
This species is endemic to southern France and eastern Spain. It is assessed as Least Concern because it has a widespread distribution, occurs in several protected areas throughout its range and its population is not expected to significantly decline in ...

A CLE11b‐CLE16 Signaling Relay Mediates Root‐Shoot‐Root Crosstalk for Drought Adaptation in Common Bean

open access: yesAdvanced Science, EarlyView.
A novel root‐shoot‐root signaling relay, mediated by CLE peptides, coordinates drought adaptation in common bean. Root‐derived PvCLE11b translocates acropetally to leaves, inducing PvCLE16 expression via PvTCP10. Leaf‐accumulated PvCLE16 triggers stomatal closure and translocates basipetally to modulate root architecture.

Note sur quelques particularités dans l'habitat de Glossina palpalis gambiensis Vanderplank, 1949 (Diptera, Glossinidae) observées au Sénégal

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1974
Il existe des particularités dans l'habitat de Glossina palpalis gambiensis à l'extrême limite de son aire de distribution au Sénégal. La sous-espèce a pu s'adapter à certains types de végétation: végétation épineuse, buissons divers en l'absence de ...

OsGSK2‐OsTCP19 Module Integrates Nitrogen and Brassinosteroid Signaling to Regulate Nitrogen Utilization and Root Growth in Rice

open access: yesAdvanced Science, EarlyView.
OsGSK2‐OsTCP19 module regulating nitrate response and lateral root (LR) development. Low‐nitrate condition results in reduced BR response, accumulation of OsGSK2 and phosphorylated OsTCP19, which suppresses the expression of nitrate‐responsive genes and LR‐development genes and impairs rice growth.
