Seedling Diversity and the Homologies of Seedling Organs in the Order Poales (Monocotyledons) [PDF]

open access: yesAnnals of Botany, 2007
Seedlings of monocots are much more diverse than those of other angiosperms, often with very derived character states. This makes morphological interpretation difficult. The morphology of seedlings of most of the 16 families of the Poales alliance are only incompletely known.

Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

open access: yesAdvanced Science, EarlyView.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

RNAi Regulator C3PO Promotes Arbovirus Infection in Insect Vectors

open access: yesAdvanced Science, EarlyView.
RNA interference (RNAi) is vital for eukaryotes to defend against virus infection. The C3PO complex takes part in RNAi but its role in regulating viral infection remains unclear. This work finds that insect C3PO facilitates arbovirus replication by degrading precursors of miRNAs, especially miR‐971‐3p.

Examining the Impact of Row Planting on Labor Use for Sustainable Food Production Among Maize Farmers in Rural Ghana

open access: yesAgribusiness, EarlyView.
ABSTRACT Smallholder farmers are reverting to traditional production methods due to the high opportunity costs and unintended consequences of new technologies. This study focuses on row planting technology, which is labor‐intensive and slow without mechanized operations.

The effect of planting stock and soil scarification on forest regeneration

open access: yesMetsanduslikud Uurimused, 2018
The present research is a comparative analysis of how the main quality indices of containerized and barerooted coniferous (Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris L.)) planting stock conform to the existing standards in ...

Drivers of Farmers' Contract Compliance Behavior: Evidence From a Case Study of Dangote Tomato Processing Plant in Northern Nigeria

open access: yesAgribusiness, EarlyView.
ABSTRACT Contract farming is a viable strategy agribusinesses rely on to strengthen coordination across actors in the value chain. However, low contract compliance remains a significant setback to agribusinesses' contract performance in low‐ and middle‐income country context.

Effects of burn season on large seedlings of oak and other hardwood regeneration three years after shelterwood harvest

open access: yesMetsanduslikud Uurimused, 2019
The effects of fall and spring prescribed fires on large seedlings (0.3 to 1.3 m height) of oak and other hardwood species three years after a shelterwood harvest were examined in Richland Furnace and Zaleski State Forests in southern Ohio.
