Effect of auxin (iaa) upon the proteolytic system in differentiating secondary xylem of pine (Pinus sylvestris L.)

Acta Societatis Botanicorum Poloniae, 2014
Effects of decapitation and IAA on proteolytic activity were studied in main stem of 4-7 year-old Pinus sylvestris trees. Proteolytic activity in the extract from differentiating secondary xylem was found to be totally reduced in decapitated 2-3 year-old

MaMPK3‐2 Phosphorylating and Stabilizing Transcriptional Repressor MaAS1 by Counteracting MaRNF4‐Mediated Ubiquitination During Banana Fruit Ripening

Plant Biotechnology Journal, EarlyView.
ABSTRACT The ripening of fleshy fruits is strongly regulated by a complex interplay between transcriptional regulation and post‐translational modifications (PTMs). However, the specific PTM regulatory networks involved in fruit ripening remain poorly understood.

Identification of the RNA m5C methyltransferase genes in Populus alba × Populus glandulosa and the role of PagTRM4B in wood formation

Forestry Research
N5-methylcytosine (m5C) RNA methylation plays an essential role in gene regulation, yet its functions in woody plant development remain poorly understood. This study systematically identified 12 putative tRNA-specific methyltransferase 4 (TRM4) homologs (

PbSnRK1‐Mediated Phosphorylation of PbTCP13 Regulates Glucose‐Responsive Lignin Biosynthesis via PbMYB11 During Pear Stone Cell Formation

Plant Biotechnology Journal, EarlyView.
ABSTRACT Stone cell lignification is a key determinant of pear fruit texture and commercial quality, and this process has been reported to be tightly coupled to cellular glucose availability. However, how glucose dose‐dependently targets transcription factor phosphorylation during lignin biosynthesis remains largely unknown.

Proteolytic activity in the stem cambial region of Pinus sylvestris L. - A contribution to the specific differentiation of secondary xylem and phloem

Acta Societatis Botanicorum Poloniae, 2014
Proteolytic activity was studied in the differentiating xylem and phloem of Scots pine (Pinus sylvestris L.) to determine the specificity of xylem and phloem differentiation.

QTL Mapping of Several Seed Quality Traits in the DH Population NPZ06 × NPZ09 (Brassica napus L.) for Marker‐Assisted Selection

Plant Breeding, EarlyView.
ABSTRACT Enhancing nutritional quality of oilseed rape requires deeper insight into the genetic control of seed quality traits. This study analysed the effect of varying soil phosphorus (P) levels on seed quality traits in the hybrid cultivar Architect. NIRS and laboratory methods were used to quantify total seed P and phytic acid (IP6) content.

Vertical Stratification Drives Divergent Spatial Trade‐Offs Among Xylem Cell Types in Angiosperm Trees of a Mountain Forest in Eastern China

Ecology and Evolution
Vertical stratification in forests acts as an ecological filter, driving woody plants to evolve specialized survival strategies. Angiosperms, in particular, develop secondary xylem with three interdependent functions—water transport, mechanical support ...

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...
