Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants

Advanced Science, EarlyView.
This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

REACTIVITY OF CHLOROPHYLL a/b‐PROTEINS AND MICELLAR TRITON X‐100 COMPLEXES OF CHLOROPHYLLS a OR b WITH BOROHYDRIDE [PDF]

Photochemistry and Photobiology, 1989
Abstract—The reaction of several plant chlorophyll‐protein complexes with NaBH4has been studied by absorption spectroscopy. In all the complexes studied, chlorophyllbis more reactive than Chia,due to preferential reaction of its formyl substituent at C‐7. The complexes also show large variations in reactivity towards NaBH4and the order of reactivity is:

Characterization of chlorophyll binding to LIL3. [PDF]

PLoS ONE, 2018
The light harvesting like protein 3 (LIL 3) from higher plants, has been linked to functions in chlorophyll and tocopherol biosynthesis, photo-protection and chlorophyll transfer. However, the binding of chlorophyll to LIL3 is unclear.

Single‐cell Transcriptome Profiling Reveals Gene Regulatory Networks and Key Genes in the Root Epidermis and Cortical Cells Associated with Early Nodulation in Glycine Max

Advanced Science, EarlyView.
Single‐cell transcriptomics of soybean roots soon after rhizobial inoculation reveals epidermal and cortical cell‐specific programs and gene‐regulatory networks acting in symbiosis establishment. We identify an ethylene‐driven regulatory circuit involving WRKY6.3/6.4 transcription factors targeting select Nod19 genes that promotes infection‐thread ...

Determination of Magnesium Isotopic Composition of Plant Chlorophylls Based on HPLC and MC-ICP-MS

Yankuang ceshi
The accurate determination of magnesium isotope values of chlorophyll a and chlorophyll b is particularly important for the study of magnesium biosynthesis pathways during chlorophyll formation. HPLC is required before MC-ICP-MS can be utilized, but HPLC

Interference of ATP‐Binding Cassette Transporter by Functional Nano‐Delivery System for High Efficiency Management of Insecticide‐Resistant Nilaparvata lugens

Advanced Science, EarlyView.
A ZIF‐90 nanocarrier delivers dinotefuran and suppresses NlABCG3 and NlABCH1 in resistant Nilaparvata lugens. This system combines pH/ATP‐triggered release with enhanced foliar retention, improving efficacy while sparing honeybees and promoting rice growth, offering a promising resistance‐breaking strategy.

The Landscape of Long Non‐Coding RNAs Provides Insights Into the Domestication and Improvement of Pear Fruit

Advanced Science, EarlyView.
This study reveals that long non‐coding RNAs represent important regulatory components underlying pear domestication and improvement. Integrative multi‐omics analyses identify selected lncRNAs associated with fruit traits, while functional validation uncovers a lignin‐related lncRNA, lncRNA‐pys, that promotes lignin accumulation.

The BTB/POZ‐MATH Protein ZmBPM1 Interacts With Autophagy‐related Protein ZmATG6 and Modulates the NLR Protein Rp1‐D21‐Mediated Defense Response in Maize

Advanced Science, EarlyView.
The maize BTB/POZ‐MATH (BPM) protein ZmBPM1 interacts with autophagy‐related protein ZmATG6 to relocate the NLR protein Rp1‐D21 from the nucleo‐cytoplasmic compartment into autophagosome‐like puncta, leading to autophagy‐mediated turnover and suppressing the hypersensitive response.

Migration of Electronic Energy from Chlorophyll b to Chlorophyll a in Solutions

Biophysical Journal, 1972
Absorption, emission, and fluorescence excitation spectra of pure solutions of chlorophyll a (Chl a) and chlorophyll b (Chl b) in diethyl ether and of equimolecular mixed solutions of the two pigments, were determined at room temperature as functions of concentration (in the range from 5 x 10(-6) M to 4 x 10(-3) M) and of wavelength of the exciting ...
