Ional crops, and their ability to accumulate a high percentage of their dry weight as triacylglycerol (TAG) under adverse environmental circumstances like nutrient deprivation. TAG is an specifically desirable compound, due to the fact it may be easily converted to biodiesel fuel by way of transesterification of its fatty acids (FAs). Microalgae accumulate TAG in the course of nutrient deprivation and break it down soon after nutrient resupply, and these processes involve dramatic shifts in cellular carbon allocation. Nitrogen (N) deprivation induces TAG synthesis, whereas N-resupply induces a coordinated degradation of TAG and also a HSP90 Antagonist Biological Activity resumption of cellular growth. However, the metabolism of TAG is just not effectively understood, particularly the contributions of FAs from distinct membrane lipids to TAG accumulation along with the fate of TAG FAs through degradation. Young and Shachar-Hill (pp. 79614) have performed isotopic labeling time course experiments working with Chlamydomonas reinhardtii to track FA synthesis and transfer in between lipid poolsAGAMOUS-like-6 function in tomato fruit setIn tomato (Solanum lycopersicum), the ovary, which develops in concert with the rest from the flower, ceases to undergo cell divisions 1 d before anthesis and enters a state referred to as “ovary arrest.” Only successful fertilization H-Ras Inhibitor Accession provokes the ovary to begin creating into fruits: unfertilized flowers, around the contrary, are soon abscised. Thus, fertilized ovules need to| PLANT PHYSIOLOGY 2021: 185; 724Minorskyemit a signal to initiate fruit set but the mechanism underlying fertilization-dependent fruit set is still not fully elucidated. Interestingly, the tomato loss-of-function mutant on the transcription factor gene AGAMOUS-like6 (SlAGL6; slagl6CR-sg1) is capable of fertilization-independent setting of standard, but seedless (i.e., parthenocarpic) fruit. To acquire insight into the mechanism of fruit set, Gupta et al. (pp. 96984) have investigated how slagl6CR-sg1 uncouples fruit initiation from fertilization. They report that the ovules on the slagl6CR-sg1 mutant had been enlarged because of integument overproliferation and failed to differentiate an endothelium, the integument’s innermost layer, upon maturation. A causal partnership amongst slagl6 loss-of-function and this abnormal phenotype is indicated by the fact that SlAGL6 ispredominantly expressed in the immature ovule integument, and upon ovule maturation, its expression shifts to the endothelium. The authors report that the transcriptome of unfertilized mutant ovules profoundly differs from that of wild-type and exhibits substantial overlap with the transcriptome of sporophytic tissues of fertilized ovules. A single prominent upregulated gene was the fertilization-induced cytochrome P450 cell proliferation regulator SlKLUH. The ectopic overexpression of SlKLUH stimulated each integument development in unfertilized ovules and parthenocarpy, suggesting that its suppression by SlAGL6 is vital for stopping fertilization-independent fruit set. These final results recommend that SlAGL6 acts from within the ovule integument as a switch that, unless turned off, prevents fruit set.
