☀️⚡ SPECIAL ISSUE REVIEW ⚡☀️ The mechanisms by which light signalling integrates environmental cues with key energy-producing and -sensing metabolic networks to balance growth, resource allocation and defence, are reviewed – SharathKumar et al. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

Fig. 2 (shortened, full legend in paper): Light signals activate the TOR pathway to mediate growth–defence trade-off decisions. The Target of Rapamycin Complex (TORC), comprising TOR and the accessory subunits RAPTOR (REGULATORY-ASSOCIATED PROTEIN OF TOR) and LST8 (LETHAL WITH SEC THIRTEEN PROTEIN 8), functions as a central regulatory hub that integrates environmental cues, such as light, with internal signals, including hormonal and energy status. TOR promotes growth under favorable conditions, but must be down-regulated during stress, such as pathogen attack, to redirect energy toward defense mechanisms. Light is a key environmental signal that stimulates photosynthesis, leading to increased energy production and sugar accumulation, both of which activate TOR signaling. As a central energy sensor, TOR is also closely linked to the circadian clock, regulating essential metabolic processes in a time-of-day-dependent manner.

🌿🍅 SPECIAL ISSUE RESEARCH 🍅🌿 The wild tomato Solanum pennellii has specialized leaf design & photosynthetic machinery that boost photosynthetic capacity, which can be transferred to commercial tomato plants via non-GM grafting methods- Ganie et al. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

Fig. 1.Whole plant leaf area and plant height of LEA and Lost. The growth patterns of LEA and Lost, particularly in terms of whole plant leaf area and height, were quantified throughout the experiment. (A) LEA consistently exhibited a significantly higher whole plant leaf area than Lost (B) Although LEA initially had greater plant height, Lost began to surpass LEA in height around 29 d after transplanting (DAT). Data are presented as mean values ±standard deviation (n=3–6). Statistical differences were assessed using Student's t-test: *P<0.05, **P<0.01, ***P<0.001.

For my latest @knowablemag.bsky.social story, I asked @leakey77.bsky.social and @proftlawson.bsky.social if we should tell plants to keep their mouths shut. knowablemagazine.org/content/arti...

Can tinkering with plant pores protect crops against drought?

It’s not an open-and-shut case. But researchers are finding out plenty by genetically altering the numbers of these openings, as well as simulating future atmospheres, and more.

Excited to see our story on epigenetic mediated aclimation of plants to fluctuating light patterns out today in doi.org/10.1111/nph..... This work started 6 years ago co-supervised with the amazing @proftlawson.bsky.social and led by the brilliant @robynemm.bsky.social. 1/2

🌱 First up, our invited speaker Christine Raines (University of Essex, UK) talking about “Improving photosynthesis for sustainable crop productivity” 🌿 Christine was JXB’s first female EIC (2012–2020) and also gave a wonderful tribute to Prof. Stephen Long during her talk. #JXB75 #PlantScience 🧪

Christine Raines (University of Essex, UK) delivering her talk on “Improving photosynthesis for sustainable crop productivity,” with slides behind her recapping the C3 cycle, at the JXB 75th Anniversary Conference in Edinburgh.

During her presentation, Christine also gave a wonderful tribute to Prof. Stephen Long (1950-2025), pictured on the slides behind her, at the JXB 75th Anniversary Conference in Edinburgh.

Throwback to a setup we fine-tuned for measuring gas exchange in tomato fruit. Optimising this protocol was key to comparing metabolic differences across genotypes during fruit development 🌱🍅 Big thanks to @proftlawson.bsky.social @andrewsimkin.bsky.social @mjtplantbiology.bsky.social

**NEW ISSUE ALERT** Issue 15 of 2024 is a special issue: 𝗥𝗲𝗱𝗼𝘅 𝗥𝗲𝗴𝘂𝗹𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗚𝗲𝗻𝗲 𝗘𝘅𝗽𝗿𝗲𝘀𝘀𝗶𝗼𝗻 Inside: 9 reviews, 3 research, 1 resource, & an editorial by the guest editors (Amna Mhamdi & Graham Noctor). academic.oup.com/jxb/issue/75... #PlantScience 🧪

The central role of redox status in modulating plant function. Oxidants and reductants produced in different compartments can transmit developmental and environmental signalling that leads to changes at multiple levels, ultimately modulating gene expression to drive plant responses to a fluctuating and frequently challenging environment. Among the panoply of redox factors existing in the cell, superoxide, hydrogen peroxide, nitric oxide, and glutathione are some of those given consideration in this issue.
